pyquery Installation Issues

problem:

In the computer terminal and can properly installed pyquery introduced, but not import pycharm, suggesting the absence of the module. Install the following error in pycharm setting in:

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

 

Cause: The current version pip no main (), without downgrading the solution is as follows:

Find pycharm installation directory helpers / packaging_tool.py file, locate the following code:

# From the line 104 begins 
DEF do_install (the pkgs):
     the try :
         Import PIP
     the 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)

Modify the following code:

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)

Method Two: downgraded version pip

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