Question

根据几个有用的相关问题的建议和指导，我已经打了几个星期这个问题，但仍然无法解决。我试图解决这个问题，不止一次卸载并重新安装了easy_install，pip，virtualenv和virtualenvwrapper。当我发送.bashrc时，我收到以下错误：

Traceback (most recent call last):
  File "/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/runpy.py", line 174, in _run_module_as_main "__main__", fname, loader, pkg_name)
  File "/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/runpy.py", line 72, in _run_code exec code in run_globals
  File "/usr/local/lib/python2.7/site-packages/virtualenvwrapper/hook_loader.py", line 16, in <module> from stevedore import ExtensionManager
ImportError: No module named stevedore
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/local/bin/python2.7 and that PATH is
set properly.

这是我的.bashrc文件：

#set -x
if [ -f /usr/local/bin/virtualenvwrapper.sh ] ; then
  source /usr/local/bin/virtualenvwrapper.sh
fi
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export PATH=/Library/Frameworks/Python.framework/Versions/2.7/bin:$PATH
export PATH=/usr/local/sbin:$PATH
export PATH=/usr/local/bin:$PATH
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python2.7
export PROJECT_HOME=$HOME/dev

我尝试将VIRTUALENVWRAPPER_PYTHON更改为/ usr / local / bin / python - 这给了我同样的错误，而不是2.7。我也试着注释掉指向2.7二进制文件的导出PATH行。这也没有用。我认为我尝试了很多事情，我可能会遇到严重破坏的事情。如果它有帮助，我使用Homebrew安装了Python，我安装了2.7.13和3.6.3。在我的/ usr / local / bin目录中，我的Python符号链接如下：

如果您使用的是Python2，则可能是从另一个Python版本安装了一个pakage。试试这个：

$ sudo pip3 install virtualenvwrapper

无法导入模块virtualenvwrapper.hook_loader
