如何全局安装Python(dev)依赖关系，这样我就不必在每个venv中都重新安装它们? [英] How to install Python (dev) dependencies globally so that I don't have to reinstall them in every venv?

问题描述

我希望在为每个项目创建的每个venv(虚拟环境)中都可以使用一些Python依赖项.例如black，flake8和pytest.那有可能吗，如果可以的话，如何实现呢?

There are a few Python dependencies that I would like to be available in every venv (virtual environment) that I create for each project. For example black, flake8 and pytest. Is that possible and if so, how to achieve that?

我想在主要的Python安装下安装这三个一次，相反，我必须在启动新项目时在我创建的每个venv中重新安装所有它们.当使用VSCode时，当您切换到尚未安装这些软件包的venv时，会弹出弹出式窗口，提示未安装Linter flake8"或"...未安装black"，这特别烦人.

I'd like to install these three once under my main Python installation, instead I have to reinstall all of them in every venv that I create when I start a new project. This is specially annoying when using VSCode which throws popups complaining about "Linter flake8 is not installed" or "...black is not installed", etc. when you switch to a venv where you haven't installed these packages.

推荐答案

一个可能的解决方案是，

• 停用虚拟环境.
• 安装需要全局可用的所有软件包.
• 再次激活虚拟环境.

• 确保您启用了从全局继承包

One Possible solution would be,

• Deactivate virtual environment.
• Install all packages which you need to be available globally.
• Again activate virtual environment.

• make sure you enable inherit package from global
