问题描述
使用 os 模块我可以获得环境变量的值.例如:
Using os module I can get the values of the environment variables. For example:
os.environ['HOME']
但是，我无法设置环境变量:
However, I cannot set the environment variables:
os.environ['BLA'] = "FOO"
它在程序的当前会话中工作，但是当我的 python 程序完成时，我没有看到它更改(或设置)环境变量的值.有没有办法从 Python 中做到这一点?
It works in the current session of the program but when I python program is finished, I do not see that it changed (or set) values of the environment variables. Is there a way to do it from Python?
推荐答案
如果你想让你的环境变量在会话中持续存在，你可以
If what you want is to make your environment variables persist accross sessions, you could
对于unix
做我们在 bash shell 中所做的事情.在 ~/.bashrc 中添加环境变量.
do what we do when in bash shell. Append you environment variables inside the ~/.bashrc.
import os
with open(os.path.expanduser("~/.bashrc"), "a") as outfile:
# 'a' stands for "append"
outfile.write("export MYVAR=MYVALUE")
或对于 Windows:
setx /M MYVAR "MYVALUE"
在 Program Files 的 Startup 中的 *.bat 中
in a *.bat that is in Startup in Program Files
