Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-install-jwovyB/Twisted/
找了网上很多文档，python官网下载scrapy包后，pip setup.py install还是一样的报错；偶然在https://stackoverflow.com/上看到一种解决方案，尝试了一下，果然成功了；但是却没有搞明白具体原因，具体操作如下：
MacBook-Pro-6:site-packages $ sudo pip install --upgrade incremental

发现提示说没有scrapy 1.5.0要求Twisted>=13.1.0，还没有安装，而Twisted在初始安装scrapy报错中有提到，觉得是有关系的，于是安装一下：

Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
有两处报错，需要安装matplotlib和不能写在six之类的，于是安装matplotlib，并且安装时把six注释掉：
