创建venv时Python设置环境变量 [英] Python set environment variable when creating venv

问题描述

在我的项目中，我使用内置的python虚拟环境( python -m venv ).
要设置环境变量，我将多个 export VAR1 = VALUE1 添加到 venv/bin/activate 的末尾.
显然，当我删除venv并创建一个新的venv时，例如使用新的python版本时，我所有的env变量都会丢失.
那么，有没有办法保存它们呢?创建venv时是否可能定义env变量?

In my project I use the built-in python virtual env (python -m venv).
To set environment variables I add multiple export VAR1=VALUE1 to the end of the venv/bin/activate.
Obviously, when I delete the venv and create a new one, for example with the new python version all my env variables get lost.
So, is there a way to preserve them? May be it is possible to define env variables when creating the venv?

推荐答案

而不是添加到 activate

export VAR1=VALUE1

考虑将它们写入自己的文件中:

consider writing them into their own file:

〜/setupenv.sh :

export VAR1=VALUE1

并将以下内容添加到 activate

source ~/setupenv.sh

但是，就我个人而言，我不会这样做.我会定义一个bash函数来做到这一点:

However, personally, I would not do that. I would instead define a bash function to do it:

myownactivate(){
  source <path_to_activate>
  export VAR1=VALUE1
}
