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

pytcharm错误：module 'pip' has no attribute 'main' 显然是因为pip文件版本不一样导致的问题

修改方法

找到安装目录下 helpers/packaging_tool.py文件。用以下代码替换原安装卸载方法\

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)

 有的模块安装错误，是因为适用于的python版本不一样。注意使用的是py2还是3\
