Question

python3.6安装Scrapy出现以下错误怎么解决

Answer 1

Running setup.py install for pycparser ... done
Running setup.py install for zope.interface ... error
Exception:
Traceback (most recent call last):
File "c:\users\46782\appdata\local\programs\python\python36\lib\site-packages\pip\compat\__init__.py", line 73, in console_to_str
return s.decode(sys.__stdout__.encoding)
UnicodeDecodeError: 'utf-8' codec can't 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。
打开c:\program files\python36\lib\site-packages\pip\compat\__init__.py约75行
return s.decode('utf_8') 改为return s.decode('cp936')
