的Python（2.7.10）：主要错误：“ID”

我试图按照教程做在Python Reddit和Twitter的僵尸。我使用的Python（2.7.10），因为我相信这是在教程中使用的版本，但我有以下错误：的Python（2.7.10）：主要错误：“ID”

Traceback (most recent call last):

看看这个[SO问题] [1] [1]：http://stackoverflow.com/questions/24816114/keyerror-when-key-exists – TM89

我正在试图使这与我的问题有关，但做得不太好。将继续，谢谢。 – user2183587

已解析的json中有哪些键（'json.loads（r.text）.keys（）'）？ –

我遇到了一些类似的问题，但我不知道这是否是同样的问题。从PRAW 3.0开始，Redditor类正在使用用于PRAW 2.x中的Subreddit类的lazyload功能。你可以使用断言（redditor.has_fetched）检查对象加载与否。

具体到类Redditor，既“ID”和“名称”被lazyload属性，以及相同的其他一些属性，如“link_karma”。我以前直接为它们进行查询：瓦尔（redditor）[“身份证”] 它的工作对PRAW 2.x和报告PRAW 3.0 我修复的错误是调用： redditor.link_karma 加载的所有功能。
