Question

我有一台安装了python并安装了virtualenvwrapper的Mac。我试图通过运行来创建一个新环境：

mkvirtualenv Test

我收到以下错误：

New python executable in /Users/sidharthnayyar/.virtualenvs/Test/bin/python
Installing setuptools, pip, wheel...done.
Traceback (most recent call last):
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/runpy.py", line 174, in _run_module_as_main

    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/runpy.py", line 72, in _run_code

    File "/Library/Python/2.7/site-packages/virtualenvwrapper/hook_loader.py", line 16, in <module>
        from stevedore import ExtensionManager
ImportError: No module named stevedore

我在这里安装了python：

$ which -a python
    /usr/local/bin/python
    /usr/bin/python

如果我尝试sudo pip install stevedore，那么它说已经安装了一些警告：

sudo /usr/local/bin/pip install stevedore

如果我尝试sudo -H pip install stevedore，那么我会收到以下错误：

如果我创建一个.bash_profile并放入其中：

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh

然后重新加载终端窗口然后我收到以下错误：

source ~/.bash_profile
Traceback (most recent call last):
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/runpy.py", line 174, in _run_module_as_main

    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/runpy.py", line 72, in _run_code
        exec code in run_globals
    File "/Library/Python/2.7/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/python and that PATH is
set properly.

好奇和好奇。

有关出了什么问题以及如何解决此问题的任何建议？

Answer 1

我也很困惑这个问题。我通过卸载旧的装卸工具并重新安装它来解决它。

sudo pip uninstall stevedore
sudo pip install stevedore

Answer 2

看起来你设法在没有stevedore的情况下安装了virtualwrapper，这是一个依赖项。尝试安装它。

pip install stevedore

Answer 3

使用python 2.7 sudo pip install stevedore

mkvirtualenv ImportError：没有名为stevedore的模块
