python - 将 '' praw.Reddit'' 分配给变量时出现 KeyError

Question

不久前我可以使用 oauth2 成功连接到 reddit 的服务器，但是当刚才运行我的脚本时，我收到一个 KeyError ，然后是一个 NoSectionError。下面的代码后面是异常，(代码已缩减至其要点)。

import praw


# Configuration
APP_UA = 'useragent'
...
...
...

r = praw.Reddit(APP_UA)

错误消息:

Traceback (most recent call last):
  File "D:\Directory\Python\lib\configparser.py", line 843, in items
    d.update(self._sections[section])
KeyError: 'useragent'

A NoSectionError occurred when handling the above exception.
"During handling of the above exception, another exception occurred:"

'Traceback (most recent call last):

Answer 1

尝试给它一个 user_agent kwarg。

r = praw.Reddit(useragent=APP_UA)
