Question

我最近通过brew（也是python2 via brew）安装了python3，并且没有触及系统python（新的笔记本电脑macOS）。

然后我用pip3 install virtualenvwrapper

安装了virtualenvwrapper

然后在我的shell（zsh）中我添加了

    #set python3 as the default for new virtualenvs
    $ export VIRTUALENV_PYTHON=python3
    # set where virtual environments will live
    export WORKON_HOME=$HOME/.virtualenvs
        # set the folder for projects
        export PROJECT_HOME=$HOME/PycharmProjects
    # ensure all new environments are isolated from the site-packages          
    export VIRTUALENVWRAPPER_VIRTUALENV_ARGS='--no-site-packages'
    # use the same directory for virtualenvs as virtualenvwrapper
    export PIP_VIRTUALENV_BASE=$WORKON_HOME
    # makes pip detect an active virtualenv and install to it
    export PIP_RESPECT_VIRTUALENV=true
    if [[ -r /usr/local/bin/virtualenvwrapper.sh ]]; then
       source /usr/local/bin/virtualenvwrapper.sh
    else
       echo "WARNING: Can't find virtualenvwrapper.sh"
    fi

然而，无论何时我运行mkvirtualenv或我收到错误：

 ...
 Installing setuptools, pip, wheel...done.
 /usr/bin/python: No module named virtualenvwrapper

即使mkvirtualenv命令似乎按预期工作。但是，mkproject并不执行workon命令。

您使用pip3在python3中安装了virtualenvwrapper，但在运行mkvirtualenv时访问了python2

使用别名技术将python3设置为默认值。您可以通过https://stackoverflow.com/a/18425592/5334188

完成此操作

还要检查virtualenvwrapper.sh路径，使用哪个

python：virtualenvwrapper部分破坏错误：没有名为virtualenvwrapper的模块
