pycharm中安装ctypes模块

在pycharm中安装ctypes模块的时候出现：
ERROR: Could not find a version that satisfies the requirement ctypes (from versions: none)
ERROR: No matching distribution found for ctypes
的错误。。。。。。。。。。

回答：
ctypes is module from the standard library, you don’t need to install it, it comes preinstalled with Python.不用安装，python中默认模块。
