关于 pycharm 安装第三方模块的一些经验

解决pycharm问题：module ‘pip‘ has no attribute ‘main‘

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：

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)

修改为如下，保存即可。

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)
