错误"Failed to initialize virtualenvwrapper." (WSL 视窗 10)

Question

简介

在Windows10上的WSL(WsmanShell命令行，版本0.2.1(中，我安装了pyenv，并尝试使用pyenv-virtualenvwrapper。然而，我似乎无法启动和运行它，即使使用与我在Ubuntu-PC中使用的.bashr和.profile配置文件也是如此。

在接下来的内容中，我将描述我所尝试的内容。

我不知道还有什么能让它发挥作用。坦率地说，同样令人震惊的是，在所有其他Ubuntu/Linux发行版上，pyenv和virtualenvwrapper应用程序都会出现不同的问题。一般来说，当他们工作时，他们是了不起的，但设置他们往往是一种痛苦。

我在mac上(BigSur 11.5.1上的bash shell上(尝试安装virtualenvrapper时遇到了同样的错误。最后我解决了这个问题：在安装pyenv和virtualenvrappper后，~/.bashrc应该是这样的：

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
export PYENV_VIRTUALENVWRAPPER_PREFER_PYVENV="true"
export WORKON_HOME=$HOME/.virtualenvs
eval "$(pyenv init -)"
pyenv virtualenvwrapper_lazy

然后是source ~/.bashrc(还要确保你的.bash_profile或.profile是源.bashrc(.
