我已经安装了python 3.5，需要安装pywin(pywin32)
然而，皮普找不到它。注意，我刚刚成功地安装了PIP'ed send2trash和gitpythonCould not find a version that satisfies the requirement pywin32 (from versions: )
一些可能相关的数据点：python 3.5的新安装
windows 7 x64
Python2.7以前安装在机器上
如前所述，其他几个包是通过PIP安装的
从git-bash运行这些命令，git-bash来自git-windows安装程序，不久前安装的。
--我的路径中有gnu grep，所以我相信我选择了git安装程序选项，将mysys的整个工具链放在我的路径中
