错误分析
执行安装指令pip install pylint，出现错误，错误信息如下：
Installing collected packages: wrapt, astroid, pylint
Running setup.py install for wrapt … error
Exception:
Traceback (most recent call last):
File “C:\\Users\\sigmarising\\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 43: invalid start byte
During handling of the above exception, another exception occurred:

Windows上很多问题都是由于编码引起的，pylint安装失败也与编码有很大关系。
解决方案
1.定位到以下文件： C:\\Users\\acanprince\\AppData\\Local\\Programs\\Python\\Python36\\Lib\\site-packages\\pip\\compat\\__init__.py 定位时需将路径中的_\\UsersNames_与_\\Python36_，更改为计算机具体情况 2.定位到文件的第75行，将源代码：
return s.decode(‘utf_8’)
更改为：
return s.decode(‘gbk’)
3.重新执行_pip install pylint_ 4.安装成功
