无法安装pyzmail - “命令”python setup.py egg_info“失败，错误代码1”

Question

我想为Python 3.4安装pyzmail。我使用Visual Studio的社区版（Windows），但也尝试使用命令行安装，并得到以下转储：

----- Installing 'pyzmail' ----- 
Collecting pyzmail 
    Using cached pyzmail-1.0.3.tar.gz 
Collecting distribute (from pyzmail) 
    Using cached distribute-0.7.3.zip 
    Complete output from command python setup.py egg_info:

     raise AttributeError(attr) 
    AttributeError: _DistInfoDistribution__dep_map 

    During handling of the above exception, another exception occurred:

Command "python setup.py egg_info" failed with error code 1 in C:\Users\user\AppData\Local\Temp\pip-build-v5zvr2p3\distribute\ 
----- Failed to install 'pyzmail' ----- 

谷歌搜索后，我检查我已经安装了ez_setup和setuptools的模块，这是我做的。任何帮助将非常感激！

我已经能够重现你的问题，你说的没错，用pip install pyzmail不会”好（pyzmail的安装程序是越野车），所以我已经试过这个：

easy_install pyzmail 

它成功，那么我可以导入pyzmail没有任何问题。
