解决PyCharm安装package问题

使用PyCharm安装package出现：AttributeError: module 'pip' has no attribute 'main'

原因是：pip更新

修改PyCharm安装目录下：helpers/packaging_tool.py，找到代码：

修改为：

def do_install(pkgs):
    try:
        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:
        try:
            from pip._internal import main
        except Exception:
            from pip import main
    except ImportError:
        error_no_pip()
    return main(['uninstall', '-y'] + pkgs)

Ctrl+S 保存
再次用PyCharm安装package即可
若再次安装出现问题：NameError: name 'pip' is not defined

则是上面修改的两个函数的返回值错误，下图红色处删除pip.就ok了
