Python - 无法安装软件包:TypeError:不可排序的类型

Python - Can#39;t Install Packages: TypeError: unorderable types: NoneType() gt;= str()(Python - 无法安装软件包:TypeError:不可排序的类型:NoneType() = str())

问题描述

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

System: 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，我都会得到以下信息:

Whenever I try to install a package, in Pycharm or via command line, I get this:

running install
running build
running build_py
running build_ext

今天早些时候，我收到无法找到 vcvarsall.bat"错误，但通过 这个话题.

Earlier today I was getting the "Unable to find vcvarsall.bat" error, but solved that with this thread.

我相信这个问题的根源在于我几周前卸载了 Visual Studio Express，因为我没有使用它.有没有办法在不重新安装 VSE 的情况下解决此错误?

I believe this problem was rooted in me uninstalling Visual Studio Express a few weeks back as I wasn't using it. Is there a way to get around this error without installing VSE again?

谢谢！

推荐答案

我通过 conda install mingw 在我的虚拟环境中解决了这个问题，然后放置

I solved this problem by conda install mingw in my virtual environment and then placing

[build]
compiler=msvc

在 Libdistutilsdistutils.cfg 中

in Libdistutilsdistutils.cfg
