Python 通过cmd（Windows）安装pylint失败

正如标题所述，我正试图使用以下命令安装pylint：

pip安装pylint

但我得到以下例外：

Exception:
Traceback (most recent call last):
  File "C:\Python34\lib\site-packages\pip\_vendor\pkg_resources.py", line 2482, in _dep_map

    raise AttributeError(attr)
AttributeError: _DistInfoDistribution__dep_map

During handling of the above exception, another exception occurred:

Storing debug log for failure in C:\Users\Haiss\pip\pip.log

有人知道是什么导致它失败的吗？我使用Anaconda安装了Python 3。我检查了调试日志，但没有提供任何其他详细信息。

尝试以下操作：

easy_install --upgrade pip

---

大部分都成功了！但是现在我得到一个错误，说colorama需要一个不同的Python。有没有办法卸载或绕过此操作？我试着运行pip卸载colorama，但它不起作用。更不用说使用easy install for everything似乎已经解决了这个问题。谢谢你的帮助。
