module 'pip' has no attribute 'main'

Pycharm安装package出现报错：module 'pip' has no attribute 'main'

 

Traceback (most recent call last):

File "D:\Program Files\JetBrains\PyCharm Community Edition 2017.3.1\helpers\packaging_tool.py", line 192, in main

retcode = do_install(pkgs)

File "D:\Program Files\JetBrains\PyCharm Community Edition 2017.3.1\helpers\packaging_tool.py", line 109, in do_install

return pip.main(['install'] + pkgs)

AttributeError: module 'pip' has no attribute 'main'

第104行

原文：

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)

改为：

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 pip.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 pip.main(['uninstall', '-y'] + pkgs)

还是出现报错

解决方案：之前更改packaging_tool.py时少改了一处。最后return处要把pip删掉。

最后修改为：

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)
