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

Question

我正在尝试为 Python 3.4 安装 pyzmail。我正在使用 Visual Studio Community Edition (Windows)，但也尝试使用命令行进行安装并获取以下转储:

 ----- 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:

    During handling of the above exception, another exception occurred:

----- Failed to install 'pyzmail' -----

谷歌搜索后，我检查了是否安装了 ez_setup 和 setuptools 模块，我确实安装了。任何帮助将不胜感激!

我已经能够重现你的问题，你是对的，使用 pip install pyzmail 不会很好(pyzmail 的安装程序有问题)所以我试过这个:

easy_install pyzmail

它成功了，然后我就可以毫无问题地导入 pyzmail。
