Praw 4.4/5.2“'Reddit'对象没有属性'subreddit'”

Question

我什么都试过了，真是束手无策。我一直收到一个错误，显示“AttributeError:'Reddit'对象没有属性'subreddit'” 我安装了praw5.2，然后卸载并手动安装了praw4.4，两次它都告诉我“praw的2.1.18版本过时了。版本5.2.0于2017年10月24日星期二发布。”当我编辑以下内容时：

reddit = praw.Reddit(client_id='8888',
                 client_secret='8888',
                 user_agent='8888_API:v1')

subreddit= r.subreddit('learnpython')

到

^{pr2}$

也就是说，旧的语法，运行良好。所以它似乎认为我有praw2.1.18，尽管我没有

完整回溯：
