NameError: name 'pip' is not defined（Python3.5）

问题： 

PyCharm IDE 创建项目或引入库提示 NameError: name 'pip' is not defined 问题解决方案

处理方法：

修改PyCharm 安装目录下文件:

PyCharm 2017.3\helpers\packaging_tool.py

修改如下方法:

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)
