python3.6安裝Scrapy出現以下錯誤怎麼解決？

Running setup.py install for pycparser ... done
Running setup.py install for zope.interface ... error
Exception:
Traceback (most recent call last):

UnicodeDecodeError: utf-8 codec cant decode byte 0xa1 in position 72: invalid start byte

During handling of the above exception, another exception occurred:

使用的是pip3 install scrapy 命令。

應該是在windows系統下吧，估計返回的錯誤值有中文，以UTF8解碼不出來，可以嘗試臨時修改出錯處的代碼，將 return s.decode(utf_8) 改為 return s.decode(cp936) 試試。安裝完再改回去

打開c:program filespython36libsite-packagespipcompat\__init__.py約75行
return s.decode(utf_8) 改為return s.decode(cp936)
