Is it possible to upgrade all Python packages at one time with pip?
Note that there is a feature request for this on the official issue tracker.

There isn't a built-in flag yet, but you can use
pip list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip install -U
Note: there are infinite potential variations for this. I'm trying to keep this answer short and simple, but please do suggest variations in the comments!
In older version of pip, you can use this instead:
pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip install -U
The grep is to skip editable ("-e") package definitions, as suggested by @jawache. (Yes, you could replace grep+cut with sed or awk or perl or...).
The -n1 flag for xargs prevents stopping everything if updating one package fails (thanks @andsens).
Works on Windows. Should be good for others too. ($ is whatever directory you're in, in command prompt. eg. C:/Users/Username>)
do
$ pip freeze > requirements.txt
open the text file, replace the == with >=
then do
$ pip install -r requirements.txt --upgrade
If you have a problem with a certain package stalling the upgrade (numpy sometimes), just go to the directory ($), comment out the name (add a # before it) and run the upgrade again. You can later uncomment that section back. This is also great for copying python global environments.
I also like the pip-review method:
py2
$ pip install pip-review
$ pip-review --local --interactive
py3
$ pip3 install pip-review
$ py -3 -m pip_review --local --interactive
You can select 'a' to upgrade all packages; if one upgrade fails, run it again and it continues at the next one.
You can use the following Python code. Unlike pip freeze, this will not print warnings and FIXME errors. For pip < 10.0.1
import pip
from subprocess import call
packages = [dist.project_name for dist in pip.get_installed_distributions()]
call("pip install --upgrade " + ' '.join(packages), shell=True)
For pip >= 10.0.1
import pkg_resources
from subprocess import call
packages = [dist.project_name for dist in pkg_resources.working_set]
call("pip install --upgrade " + ' '.join(packages), shell=True)
Here is my variation on rbp's answer, which bypasses "editable" and development distributions. It shares two flaws of the original: it re-downloads and reinstalls unnecessarily; and an error on one package will prevent the upgrade of every package after that.
pip freeze |sed -ne 's/==.*//p' |xargs pip install -U --
Related bug reports, a bit disjointed after the migration from bitbucket:
You can just print the packages that are outdated
pip freeze | cut -d = -f 1 | xargs -n 1 pip search | grep -B2 'LATEST:'
when using a virtualenv and if you just want to upgrade packages added to your virtualenv, you may want to do:
pip install `pip freeze -l | cut --fields=1 -d = -` --upgrade
Windows version after consulting excellent documentation for FOR by Rob van der Woude
for /F "delims===" %i in ('pip freeze -l') do pip install -U %i
From https://github.com/cakebread/yolk :
$ pip install -U `yolk -U | awk '{print $1}' | uniq`
however you need to get yolk first:
$ sudo pip install -U yolk
@Ramana's answer worked the best for me, of those here, but I had to add a few catches:
import pip
for dist in pip.get_installed_distributions():
if 'site-packages' in dist.location:
try:
pip.call_subprocess(['pip', 'install', '-U', dist.key])
except Exception, exc:
print exc
The site-packages check excludes my development packages, because they are not located in the system site-packages directory. The try-except simply skips packages that have been removed from PyPI.
@endolith: I was hoping for an easy pip.install(dist.key, upgrade=True), too, but it doesn't look like pip was meant to be used by anything but the command line (the docs don't mention the internal API, and the pip developers didn't use docstrings).
To upgrade all local packages; you could use pip-review:
$ pip install pip-review
$ pip-review --local --interactive
pip-review is a fork of pip-tools. See pip-tools issue mentioned by @knedlsepp. pip-review package works but pip-tools package no longer works.
pip-review works on Windows since version 0.5.
You can try this :
for i in ` pip list|awk -F ' ' '{print $1}'`;do pip install --upgrade $i;done
Sent through a pull-request to the pip folk; in the meantime use this pip library solution I wrote:
from pip import get_installed_distributions
from pip.commands import install
install_cmd = install.InstallCommand()
options, args = install_cmd.parse_args([package.project_name
for package in
get_installed_distributions()])
options.upgrade = True
install_cmd.run(options, args) # Chuck this in a try/except and print as wanted
I have tried the code of Ramana and I found out on Ubuntu you have to write sudo for each command. Here is my script which works fine on ubuntu 13.10:
#!/usr/bin/env python
import pip
from subprocess import call
for dist in pip.get_installed_distributions():
call("sudo pip install --upgrade " + dist.project_name, shell=True)
The following one-liner might prove of help:
pip list --format legacy --outdated | sed 's/(.*//g' | xargs -n1 pip install -U
xargs -n1 keeps going if an error occurs.
If you need more "fine grained" control over what is omitted and what raises an error you should not add the -n1 flag and explicitly define the errors to ignore, by "piping" the following line for each separate error:
| sed 's/^<First characters of the error>.*//'
Here is a working example:
pip list --format legacy --outdated | sed 's/(.*//g' | sed 's/^<First characters of the first error>.*//' | sed 's/^<First characters of the second error>.*//' | xargs pip install -U
Isn't this more effective?
pip3 list -o | grep -v -i warning | cut -f1 -d' ' | tr " " "\n" | awk '{if(NR>=3)print}' | cut -d' ' -f1 | xargs -n1 pip3 install -U
pip list -o lists outdated packages;grep -v -i warning inverted match on warning to avoid errors when updatingcut -f1 -d1' ' returns the first word - the name of the outdated package;tr "\n|\r" " " converts the multiline result from cut into a single-line, space-separated list;awk '{if(NR>=3)print}' skips header linescut -d' ' -f1 fetches the first columnxargs -n1 pip install -U takes 1 argument from the pipe left of it, and passes it to the command to upgrade the list of packages.This option seems to me more straightforward and readable:
pip install -U `pip list --outdated | awk '{ print $1}'`
(awk '{ print $1}' selects the first word of the line (separated by a space))
And this version allows for the suppression of warning message from pip list --outdated:
pip install -U `pip list --outdated | awk '!/Could not|ignored/ { print $1}'`
(awk '!/<pattern>/' removes line containing a given pattern. In my case the warning messages include "Could not" and "ignored" respectively)
This could also be used to tackle the coming default columns format:
pip install -U `pip list --format=columns --outdated | awk '!/Package|---/{ print $1}'`
This seemed to work for me...
pip install -U $(pip list --outdated|awk '{printf $1" "}')
I used printf with a space afterwards to properly separate the package names.
here is another way of doing with a script in python
import pip, tempfile, contextlib
with tempfile.TemporaryFile('w+') as temp:
with contextlib.redirect_stdout(temp):
pip.main(['list','-o'])
temp.seek(0)
for line in temp:
pk = line.split()[0]
print('--> updating',pk,'<--')
pip.main(['install','-U',pk])
The rather amazing yolk makes this easy.
pip install yolk3k # don't install `yolk`, see https://github.com/cakebread/yolk/issues/35
yolk --upgrade
For more info on yolk: https://pypi.python.org/pypi/yolk/0.4.3
It can do lots of things you'll probably find useful.
This seems more concise.
pip list --outdated | cut -d ' ' -f1 | xargs -n1 pip install -U
Explanation:
pip list --outdated gets lines like these
urllib3 (1.7.1) - Latest: 1.15.1 [wheel]
wheel (0.24.0) - Latest: 0.29.0 [wheel]
In cut -d ' ' -f1, -d ' ' sets "space" as the delimiter, -f1 means to get the first column.
So the above lines becomes:
urllib3
wheel
then pass them to xargs to run the command, pip install -U, with each line as appending arguments
-n1 limits the number of arguments passed to each command pip install -U to be 1
Windows Powershell solution
pip freeze | %{$_.split('==')[0]} | %{pip install --upgrade $_}
Here is a scripts that only updates the outdated packages.
import os, sys
from subprocess import check_output, call
file = check_output(["pip.exe", "list", "--outdated", "--format=legacy"])
line = str(file).split()
for distro in line[::6]:
call("pip install --upgrade " + distro, shell=True)
My script:
pip list --outdated --format=legacy | cut -d ' ' -f1 | xargs -n1 pip install --upgrade
More Robust Solution
For pip3 use this:
pip3 freeze --local |sed -rn 's/^([^=# \t\\][^ \t=]*)=.*/echo; echo Processing \1 ...; pip3 install -U \1/p' |sh
For pip, just remove the 3s as such:
pip freeze --local |sed -rn 's/^([^=# \t\\][^ \t=]*)=.*/echo; echo Processing \1 ...; pip install -U \1/p' |sh
OSX Oddity
OSX, as of July 2017, ships with a very old version of sed (a dozen years old). To get extended regular expressions, use -E instead of -r in the solution above.
Solving Issues with Popular Solutions
This solution is well designed and tested1, whereas there are problems with even the most popular solutions.
The above command uses the simplest and most portable pip syntax in combination with sed and sh to overcome these issues completely. Details of sed operation can be scrutinized with the commented version2.
Details
[1] Tested and regularly used in a Linux 4.8.16-200.fc24.x86_64 cluster and tested on five other Linux/Unix flavors. It also runs on Cygwin64 installed on Windows 10. Testing on iOS is needed.
[2] To see the anatomy of the command more clearly, this is the exact equivalent of the above pip3 command with comments:
# match lines from pip's local package list output
# that meet the following three criteria and pass the
# package name to the replacement string in group 1.
# (a) Do not start with invalid characters
# (b) Follow the rule of no white space in the package names
# (c) Immediately follow the package name with an equal sign
sed="s/^([^=# \t\\][^ \t=]*)=.*"
# separate the output of package upgrades with a blank line
sed="$sed/echo"
# indicate what package is being processed
sed="$sed; echo Processing \1 ..."
# perform the upgrade using just the valid package name
sed="$sed; pip3 install -U \1"
# output the commands
sed="$sed/p"
# stream edit the list as above
# and pass the commands to a shell
pip3 freeze --local |sed -rn "$sed" |sh
[3] Upgrading a Python or PIP component that is also used in the upgrading of a Python or PIP component can be a potential cause of a deadlock or package database corruption.
I had the same problem with upgrading. Thing is, i never upgrade all packages. I upgrade only what i need, because project may break.
Because there was no easy way for upgrading package by package, and updating the requirements.txt file, i wrote this pip-upgrader which also updates the versions in your requirements.txt file for the packages chosen (or all packages).
Installation
pip install pip-upgrader
Usage
Activate your virtualenv (important, because it will also install the new versions of upgraded packages in current virtualenv).
cd into your project directory, then run:
pip-upgrade
Advanced usage
If the requirements are placed in a non-standard location, send them as arguments:
pip-upgrade path/to/requirements.txt
If you already know what package you want to upgrade, simply send them as arguments:
pip-upgrade -p django -p celery -p dateutil
If you need to upgrade to pre-release / post-release version, add --prerelease argument to your command.
Full disclosure: I wrote this package.
The simplest and fastest solution that I found in the pip issue discussion is:
sudo -H pip install pipdate
sudo -H pipdate
How about:
pip install -r <(pip freeze) --upgrade
use awk update packges: pip install -U $(pip freeze | awk -F'[=]' '{print $1}')
The shortest and easiest on Windows.
pip freeze > requirements.txt && pip install --upgrade -r requirements.txt && rm requirements.txt
