无法从GoLang中的/ etc / profile获取环境变量

I've set some environment variables in /etc/profile, I can access them from bash, but for some reason I cant get them from Go.

/etc/profile:

...
TEST_ENV=test_me

I can access it from bash:

echo $TEST_ENV
test_me

I can't access this variable from GO

os.Getenv("TEST_ENV") // returns ""

If I list the available environment variables with

os.Environ()

I don't see the variable I'm looking for, but there a few variables that might help:

SHELL=/bin/sh
USER=root
LOGNAME=root

I guess my problem is related to different sessions and shells, so I even tried running

exec.Command("source /etc/profile")

and get the variables after, but it still returns nothing.

Can you give me some tips how to get environment variables if they're set in /etc/profile? I'd prefer getting them from that file, but if necessary, I can put the variables in a different place as well.

When you set an environment variable in bash, by default it isn't exported. Only exported environment variables are passed along to processes created by the shell (i.e., programs that you run). Try export TEST_ENV=test_me.
