3.vs配置截图

4.试过但无效的解决解决方案
修改pip源
百度
google
修改mimetypes.py成utf-8

Answer 1

好尴尬，我这边瞬间就安装好了

你找到python的安装包，双击运行，卸掉pip，然后重新安装下pip试试

Answer 2

更新pip 吧

python.exe -m pip install -U pip

还有 urllib2 是 python2 的标准库，python2 不用安装
Python3 将urllib2 分离成 urllib.request and urllib.error, 没有urllib2这个库

Note The urllib2 module has been split across several modules in Python 3 named urllib.request and urllib.error.

Answer 3

使用 pip 的时候打开 cmd 使用超级管理员。 urllib2这个模块是 python2自带的，你安装一个其他的模块试下。另外urllib2这种 http 模块有点过时了，建议你使用 requests

Answer 4

更新pip试试。不行就下载解压版的pip（版本高一点）

Answer 5

到 http://www.lfd.uci.edu/~gohlke/pythonlibs/ 或者 https://pypi.python.org/pypi 下载离线包. 然后用 pip install xxxxxx.whl 来安装.

Answer 6

你机器上面有两个版本的python 卸载一个版本 试试
