将更改从供应商目录推送到composer包的最快方法

I have a Laravel project and I'm using a composer. I have a library in it and I've found a small bug there. It's my custom library under the git.

What is the fastest way to push that changes?

The only way I see from now is to:

git clone my library to some temporary folder
Remember and copy-paste all the changes(cause I was fixing but in the /vendor dir)
Run composer update

Could be there any other, faster way? I'd like make changes right in the vendor dir and somehow push that changes.

P.S. As an answer I want to receive

No, it's impossible to do faster because of x, y, z.

Yes, you can. For that you have to do x, y, z.

Untested…

Linux or macOS: Yes, you can. For that you have to do something like

Store your new code somewhere else as backup:

mv …/vendor/mylib/ …/vendor/mylib_backup/

Optional: Delete your temp repo:
```
rm -r ~/git/mylib/
```
Clone your repo:
```
git clone repo-url ~/git/mylib
```
Create a symlink so that if you go into …/vendor/mylib you are really in ~/git/mylib:
```
ln -s ~/git/mylib …/vendor/mylib
```
Run
```
composer update
```
Run
```
git status
```

Maybe you get some artefacts. You can ignore them in a .gitignore file.

Which system do you use? To create a symlink on Windows you can try mklink IIRC.
