如何在 Mac (2021) 上安装 `virtualenvwrapper`？

Question

我正在努力寻找仍然相关的教程。 自 2021 年起，

virtualenvwrapper

在 Mac (OS 11.4) 上不再适用吗？

我打开我的

zsh

时得到这个：

/Library/Developer/CommandLineTools/usr/bin/python3: Error while finding module specification for 'virtualenvwrapper.hook_loader' (ModuleNotFoundError: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 and that PATH is
set properly.

➜  ~ echo $VIRTUALENVWRAPPER_PYTHON
/usr/bin/python3
➜  ~ which virtualenv
/usr/local/bin/virtualenv
➜  ~ which virtualenvwrapper.sh
/usr/local/bin/virtualenvwrapper.sh

我的

~/.zshrc

包含：

export PATH=/usr/local/bin:$PATH
export PATH="/usr/local/sbin:$PATH"

# For virtualenvwrapper
export PATH=/usr/local/share/python:$PATH
export WORKON_HOME=${HOME}/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
#export VIRTUALENVWRAPPER_VIRTUALENV=${HOME}/.local/bin/virtualenv
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
source $(which virtualenvwrapper.sh) 

我不再通过从 https://www.python.org/downloads/下载的 Mac 安装程序安装 python3。

我似乎安装了不少于三个 python3:

/usr/bin/python3
/usr/local/bin/python3
/Library/Developer/CommandLineTools/usr/bin/python3

我最近尝试使用

brew

安装 python3 失败了

pygobject

:

➜  ~ brew reinstall pygobject

我仍然不知道为什么所有的 python3 版本和位置，但标准化

/usr/local/bin

似乎解决了我的问题。

# For virtualenvwrapper
export PATH=/usr/local/bin:$PATH                                            
export WORKON_HOME=${HOME}/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh
