好好把这段给鸡翻一下，你看是不是 pip 跟 python 版本不对应

@neoblackcap
@gkiwi
Command "python setup.py egg_info" failed with error code 1 in C:\Users\cgy\AppData\Local\Temp\pip-build-wwuh4pnj\cffi\
这是怎么回事呢？

@q397064399 我 pip 的版本是最新的 9.01 ，应该不会吧

windows 下安装库？

你安装了 Microsoft Visual C++ Compiler for Python 2.7 或者 Microsoft Visual C++ Compiler for Python 3.4 了吗

你需要 http://www.lfd.uci.edu/~gohlke/pythonlibs/

你是不是还装了 Python2.x 版，可能是用了 2.x 对应的 pip

@lrh3321 为什么我百度不到安装包呢？能不能给个链接

chenguoyu

2016-11-30 11:29:36 +08:00

@LeGendAI 我已经卸载了，难道是没卸载干净？

@chenguoyu 你可以 pip -V 看看是不是 3.x 的版本

2016-11-30 11:51:53 +08:00

@chenguoyu https://www.microsoft.com/en-us/download/details.aspx?id=44266 2.7 的

3.x 版本的话，我是直接装了 VS 2015. 你试试 Visual C++ Build Tools
http://landinghub.visualstudio.com/visual-cpp-build-tools 有没有用吧

最近 pypi 源抽风

2016-11-30 13:19:30 +08:00

跟 VC 和 PIP 版本都没关系就是个参数问题， pip install --index-url http://pypi.doubanio.com/simple/ requests --trusted-host pypi.doubanio.com ，需要用这个参数“-trusted-host pypi.doubanio.com ”，否则为不信任源

yunfengjiang

2016-11-30 13:24:38 +08:00

命令后加上--trusted-host pypi.doubanio.com 这个参数 pip install --index-url http://pypi.doubanio.com/simple/ requests --trusted-host pypi.doubanio.com

@LeGendAI
pip 9.0.1 from C:\Users\cgy\AppData\Roaming\Python\Python36\site-packages (python 3.6)
没有问题呀

给了管理员权限了吗

@misaka19000 给了，但是没用啊。而且一般是不用给管理员权限的吧

现在换成清华的镜像是可以的，可是报了个新的错
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\cl.exe' failed with exit status 2
好像是编译器的问题，但是还是无法解决
