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

通过pycharm创建Django项目是出现如下错误

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

环境信息：pycharm2017.3.1（Professional Edition）、python3.6.5 (64位)、pip10.0.1、Django2.0.5

错误原因：由于pip 10版本中没有main()，如果在不降级的情况下，修改这个文件

找到pycharm安装目录下的packaging_tool.py

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)

修改成如下内容

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)

另外一种方式，降级pip的版本

python -m pip install --upgrade pip==9.0.3
---------------------

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)
