Question

新编码，我想我已经彻底搜索了这个问题的答案，但建议的解决方案并没有为我工作。不过，如果这是重复的话，请道歉！

我正在尝试根据these instructions设置我的计算机，目前正试图让virtualenv启动并运行。但是，pip似乎没有正常工作。我能够使用python -m pip作为解决方法并使用以下方法安装virtualenv：python -m pip install virtualenv

但是同样的解决方法似乎不适用于virtualenvwrapper：python -m pip install virtualenvwrapper给了我这个错误：

Exception:
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip/basecommand.py", line 215, in main
    status = self.run(options, args)

    MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")
TypeError: __call__() takes exactly 2 arguments (1 given)

如果我尝试使用pip命令直接运行任何内容，例如pip install virtualenvwrapper，我会收到此错误：

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/Library/Python/2.7/site-packages/pkg_resources/__init__.py", line 72, in <module>
    import packaging.requirements
  File "/Library/Python/2.7/site-packages/packaging/requirements.py", line 59, in <module>
    MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")
TypeError: __call__() takes exactly 2 arguments (1 given)

我有一台运行Sierra的Mac（10.12.4）。 Python版本2.7.6。 Pip 9.0.1

思考？谢谢！
