解決pycharm安裝package報錯: AttributeError: module 'pip' has no attribute 'main'

更新pip之後，Pycharm安裝package出現以下錯誤：

Error occurred:
AttributeError:module 'pip' has no attribute 'main'
Proposed solution:
Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at 'E:\python\Python_Demo\venv\Scripts\python.exe'.

command output:
Traceback (most recent call last):
  File "D:\Program Files (x86)\PyCharm 2017.3\helpers\packaging_tool.py", line 192, in main
    retcode = do_install(pkgs)
  File "D:\Program Files (x86)\PyCharm 2017.3\helpers\packaging_tool.py", line 109, in do_install
    return pip.main(['install'] + pkgs)
AttributeError: module 'pip' has no attribute 'main'


解決方法如下：
找到安裝目錄下 helpers/packaging_tool.py文件，找到如下代碼：

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)

 

 

修改爲如下，保存。重啓pycharm，即可完美解決。

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)
