pycharm 问题：module 'pip' has no attribute 'main' 



更新pip之后，Pycharm安装package出现报错：module 'pip' has no attribute 'main'


找到安装目录下 helpers/packaging_tool.py文件，找到如下代码：




 1 def do_install(pkgs):
 2     try:
 3         import pip
 4     except ImportError:
 5         error_no_pip()
 6     return pip.main(['install'] + pkgs)
 7  
 8  
 9 def do_uninstall(pkgs):
10     try:
11         import pip
12     except ImportError:
13         error_no_pip()
14     return pip.main(['uninstall', '-y'] + pkgs)   
15  




修改为如下，保存即可。




 1  
 2 def do_install(pkgs):
 3     try:
 4         # import pip
 5         try:                                #修改位置1
 6             from pip._internal import main
 7         except Exception:
 8             from pip import main
 9     except ImportError:
10         error_no_pip()
11     return main(['install'] + pkgs)         #修改位置2
12  
13  
14 def do_uninstall(pkgs):
15     try:
16         # import pip
17         try:                                  #修改位置3
18             from pip._internal import main
19         except Exception:
20             from pip import main
21     except ImportError:
22         error_no_pip()
23     return main(['uninstall', '-y'] + pkgs)     #修改位置4
