同样的，我用pip install scrapy 时也是同样的一大串错，和这个一摸一样。
到底怎么回事呢？问题解决不了很难受

为什么要升级pip库?从没这么做过，不行你就卸载了装个新版ｐｙｔｈｏｎ咯
需要什么PIP 安装不上 你就去官网下wheel 文件 pip安装就ＯＫ了

pythonDemo

你的python 什么版本的，我建议你最好装3.4版本和2.7版本，兼容性比较好。安装第三方包不容易出错，安装的时候最好用代理，我用的代理叫梯子。你百度翻墙梯子第一个。python3自带pip，命令行下用pip3 ，有错的话直接复制错误最下面一行代码取百度或者google找，基本都能找到

下载pip，进入目录用python setup.py install试试
