在Windows XP上安装Python 2.7之后，然后手动将 %PATH% 设置为 python.exe （为什么python安装程序不会这样做？），然后安装 setuptools 0.6c11 （为什么python安装程序不执行此操作？），然后手动将 %PATH% 设置为 easy_install.exe （安装程序为什么不这样做？），我终于尝试用 easy_install 安装一个python包，但是当它无法安装pywin32软件包时， easy_install 失败了，这是一个依赖项 . How can I make easy_install work properly on Windows XP? 失败如下：

一个问题是easy_install被设置为下载和安装.egg文件或源发行版（包含在.tgz，.tar，.tar.gz，.tar.bz2或.zip文件中） . 它不知道如何处理PyWin32扩展，因为它们被放置within a separate installer executable . 您需要下载相应的PyWin32安装程序文件（适用于Python 2.7）并自行运行 . 当您再次运行easy_install时（如果您已正确安装它，就像在Sergio的说明中那样），您应该看到您的winpexpect软件包已正确安装 .
由于我们正在谈论它的Windows和开源，它通常是安装方法的混乱组合，以使事情正常工作 . 但是，easy_install仍然比手动编辑配置文件更好 .
如果您使用的是Windows 7 64位版本，则可在此处找到解决方案：http://pypi.python.org/pypi/setuptools
即，你需要下载一个python脚本，运行它，然后easy_install将从命令行正常工作 .
附：我同意原始的海报说这应该开箱即用 .
我也同意OP，所有这些东西都应该在Python中设置 . 我想我们将不得不处理它直到那一天到来 . 这是一个实际上对我有用的解决方案：
installing easy_install faster and easier
我希望它可以帮助你或任何有同样问题的人！
从以下URL复制以下脚本“ez_setup.py”
https://bootstrap.pypa.io/ez_setup.py
并将其复制到Python位置
运行命令
这将在Scripts目录下安装easy_install
从Scripts目录>运行轻松安装
首先，它说你已经安装了该模块 . 如果你需要升级它，你应该这样做：
easy_install -U packageName
当然，如果包中有一些需要编译的C头并且没有安装正确版本的Visual Studio，easy_install也不能很好地工作 . 您可以尝试使用pip或distribute而不是easy_install，看看它们是否更好用 .
如果您正在使用Anaconda's Python发行版，
你可以通过pip安装它
pip install setuptools然后将其作为模块执行
python -m easy_install
