今天安sqlalchemy 发现安装会提示UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb6 in position 34: invalid start byte
具体错误信息如下
C:\Users\MythHack>pip --no-cache-dir install sqlalchemy

During handling of the above exception, another exception occurred:

然后老习惯
Lib\site-packages
新建文件：sitecustomize.py
import sys
sys.setdefaultencoding('gb2312')
sys.setdefaultencoding('gb2312')
Traceback (most recent call last):
File "", line 1, in
AttributeError: module 'sys' has no attribute 'setdefaultencoding'
??????wtf?
然后想起来，最近换了python3 查了查说
python3不支持sys.setdefaultencoding('gb2312')
那这个怎么弄啊！b了狗、。、
后来以为是编译器有问题。。又折腾了折腾
Microsoft Visual C++ Compiler for Python 2.7
发现不是这个的问题。。
仔细又看了一眼报错
File "d:\python36\lib\site-packages\pip\compat__init__.py", line 75, in console_to_str
return s.decode(sys.__stdout__.encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb6 in position 34: invalid start byte
直接去d:\python36\lib\site-packages\pip\compat__init__.py 修改了75行为
return s.decode('gb2312')
