Erro:
C:\Software\Python\Scripts>pip install imutils
File "c:\software\python\lib\runpy.py", line 193, in _run_module_as_main
"__main__", mod_spec)
File "c:\software\python\lib\runpy.py", line 85, in _run_code
exec(code, run_globals)
File "C:\Software\Python\Scripts\pip.exe\__main__.py", line 5, in <module>
ImportError: cannot import name 'main'
解决1、需要打开C:\Software\Python\Scripts\pip.exe\__main__.py（line 193， line 85，依次需要修改，这里是可以打开的）
将line 5行main 更为为_main (据网上查阅是pip更新产生的问题，win10暂时没有找到__main__.py文件，Linux可以尝试下，未亲测，那网友尝试可以解决请留言)
解决2:easy_install命令安装（结果表明imutils 成功安装）
C:\Software\Python\Scripts>easy_install imutils
