module 'pip' no attribute 'main'

python 更新pip后pycharm运行报错:module ‘pip’ no attribute ‘main’

打开pycharm安装目录找到helpers\packaging_tool.py文件建议用管理员身份运行pycharm打开文件因为python对缩进有严格要求用pycharm会比较方便不然前后缩进不一致会报缩进错误
在文件中找到do_install()和do_uninstall()方法将其改为

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


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

一定要注意缩进然后重启pycharm完美解决
