更新pip之後，Pycharm安裝package出現報錯：module 'pip' has no attribute 'main'

找到安裝目錄下 helpers/packaging_tool.py檔案，找到如下程式碼：

 

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


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

修改為如下，儲存即可。

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)
