解決pycharm問題：module ‘pip’ has no attribute ‘main’

修改 do_install和 do_uninstall

def do_install(pkgs):
    try:
        #import pip
        try:
        	from pip._internal import main
        except Exception:
        	from pip import main
    except ImportError:
        error_no_pip()
    return main(
 
['install'] + pkgs)


def do_uninstall(pkgs):
    try:
        #import pip
        try:
        	from pip._internal import main
        except Exception:
        	from pip import main
    except ImportError:
        error_no_pip()
    return main(['uninstall', '-y'] + pkgs)
