The main reason is that the user directory encoding uses Chinese, the solution is as follows:
The pip install python package loads my user directory, which happens to be Chinese and ascii can't encode it.
The solution:
python catalog Python27\Lib\site-packages build a file
Content writing:
import sys ('gb2312')
python will run this file automatically.
Above this perfect solution to Python 2.7 can not normally use pip install problem is all I have shared with you, I hope to be able to give you a reference, and I hope you support me more.
