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：

修改为如下，保存即可。

def do_install(pkgs):

try:

# import pip

try:

from pip._internalimport main

except Exception:

from pipimport main

except ImportError:

error_no_pip()

return main(['install'] + pkgs)

def do_uninstall(pkgs):

try:

     # import pip

try:

from pip._internalimport main

except Exception:

from pipimport main

except ImportError:

error_no_pip()

return main(['uninstall','-y'] + pkgs)
