Python - 无法安装包:TypeError:unorderable类型:NoneType()> = str()

Question

系统:Win7 64,Python 3.4,Pycharm 3.0.2,MinGW

每当我尝试在Pycharm中或通过命令行安装软件包时,我都会得到:

running install
running build
running build_py
running build_ext
Traceback (most recent call last):
  File "C:\Users\MyAccount\Downloads\scandir-master\scandir-master\setup.py", line 48, in <module> 'Programming Language :: Python :: Implementation :: CPython',

  File "C:\Python34\lib\distutils\cygwinccompiler.py", line 126, in __init__ if self.ld_version >= "2.10.90":
TypeError: unorderable types: NoneType() >= str()

今天早些时候我得到了"无法找到vcvarsall.bat"错误,但是用这个帖子解决了这个问题.

我相信这个问题根源于我在几周前卸载Visual Studio Express,因为我没有使用它.有没有办法绕过这个错误而不再安装VSE？

谢谢!
