HELLO! I come here by Google. I notice that the asker is a Chinese, the same to me. So, maybe we face the same problem. Then I register this website. Oh, sorry for my bad English!

I HAVE FIND THE RIGHT ANSWER!

It is because when Python install some packages, it will check the Windows Registry, some Chinese software like Aliwangwang import 'gbk' value to the HKEY_CLASSES_ROOT. So Python doesn't work.

It can be solved like this:

open C:\Python27\Lib\ mimetypes.py with Notepad ++ or other editor, then search the line " default_encoding = sys.getdefaultencoding()". add codes to the line above like this:

1 if sys.getdefaultencoding() != 'gbk': 
2     reload(sys)
3     sys.setdefaultencoding('gbk')
4 default_encoding = sys.getdefaultencoding()

 

簡單來講，就是有些國內軟件修改註冊表致使python沒法安裝庫，要改下lib目錄下的代碼。
