在python（Mac）上安装模块时遇到问题
我对使用pip在Python上安装模块有点陌生。我相信我已经安装了pip，但是当我尝试使用我尝试使用pip安装的模块时，它说没有这样的模块。我将发布终端响应，看看发生了什么。如果有人能让我知道我在安装模块时出错，我将不胜感激，谢谢你抽出时间在python（Mac）上安装模块时遇到问题,python,macos,module,pip,Python,Macos,Module,Pip,我对使用pip在Python上安装模块有点陌生。我相信我已经安装了pip，但是当我尝试使用我尝试使用pip安装的模块时，它说没有这样的模块。我将发布终端响应，看看发生了什么。如果有人能让我知道我在安装模块时出错，我将不胜感激，谢谢你抽出时间 faizrahman@138-38-186-80 ~ % sudo pip install matplotlib Password: DEPRECATION: Python 2.7 reached the end of its life on January
