Python:无法访问新定义的环境变量 [英] Python: can't access newly defined environment variables

问题描述

我无法访问我的环境变量:

I can't access my env var:

import subprocess, os
print os.environ.get('PATH') # Works well
print os.environ.get('BONSAI') # doesn't work

但是env var很好地添加到了我的/home/me/.bashrc中:

But the env var is well added in my /home/me/.bashrc:

BONSAI=/home/me/Utils/bonsai_v3.2
export BONSAI

我可以从新终端访问此环境变量.

And I can access this env var from a new terminal.

推荐答案

更新.bashrc后，执行source ~/.bashrc来应用更改.

After updating your .bashrc, perform source ~/.bashrc to apply the changes.

还将两个与BONSAI相关的调用合并为一个:

Also, merge the two BONSAI-related calls into one:

export BONSAI=/home/me/Utils/bonsai_v3.2

更新:实际上，这是试图为某些基于Eclipse的IDE更新环境的尝试.这是一个完全不同的用例. Eclipse 此处.

UPDATE: It was actually an attempt to update the environment for some Eclipse-based IDE. This is a different usecase altogether. It should be described in the Eclipse help. Also, a similar question was answered here.
