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)
