python - 试图更新matplotlib；完全失去它

Question

在我的 Mac OSX 机器上，我无法使用 python2-7 导入 mpl_toolkits。我想我会通过升级 matplotib 来解决这个问题。我试过了

sudo pip install --U matplotlib

这是一个非常长的错误消息，我将在这个问题的末尾显示。

然后，在云雀中，我尝试删除 sudo：

pip install --U matplotlib

它因错误而失败

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/kiwisolver.so'
Consider using the `--user` option or check the permissions.

有没有搞错？我认为。我会再试一次 sudo 。它失败并出现新错误：

  Found existing installation: six 1.4.1
Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

现在这是真正的踢球者：我根本无法再导入 matplotlib：

>>> import matplotlib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/matplotlib/__init__.py", line 125, in <module>
    raise ImportError("matplotlib requires pyparsing")
ImportError: matplotlib requires pyparsing

那么，谁能告诉我至少如何回到可用的matplotlib？以及如何更新它并访问 mpl_toolkits 也很棒。

顺便说一句，我提到的那个长错误是：
