我有一台装有Python和virtualenvwrapper的Mac电脑。我正在尝试通过以下方式创建一个新环境:
mkvirtualenv Test
To which I get the following error:
New python executable in /Users/sidharthnayyar/.virtualenvs/Test/bin/python
Installing setuptools, pip, wheel...done.
Traceback (most recent call last):

我已在此安装了Python：
$ which -a python
/usr/local/bin/python
/usr/bin/python
如果我尝试使用sudo pip install stevedore命令，则会显示已安装该软件包，并附有一些警告信息：
sudo /usr/local/bin/pip install stevedore

如果我创建了一个.bash_profile文件，并将以下内容放入其中：
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
当我重新打开终端窗口时，我遇到了以下错误：
source ~/.bash_profile

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.
好奇而更加好奇。
有什么关于这个问题出错的建议和如何解决的方法吗？
谢谢 Sidharth
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin。另一个答案说我需要将virtualenv安装路径放入我的PATH中。但是virtualenv在/usr/local/bin中 - 而且我的PATH，如上所述，确实有这个路径。第三个答案说python路径在不同的位置。所以我更改了bash_profile（现在在问题中）来指定python路径，但它给出了另一个错误。 - SKNwhich -a python/usr/local/bin/python/usr/bin/python这是我在bash_profile中设置的VIRTUALENVWRAPPER_PYTHON，但是它会产生类似的错误。第四个答案说他通过easy_install安装了virtualenv，所以他必须通过pip重新安装。我不知道virtualenv是如何安装在我的机器上的（或者如何检查），但它位于/usr/local/bin，所以我使用sudo /usr/local/bin/pip uninstall virtualenv卸载了它，然后通过sudo /usr/local/bin/pip install virtualenv进行了安装，但没有帮助。 - SKN
