我遇到这样的问题，在要刷的课有名额的时候，验证码识别错误终端输出如下

Reproduce

如有必要，提供复现的步骤

发现好像是自己运行的时候没有打开对应的虚拟环境，结合之前打开虚拟环境后运行成功，所以认为这个问题暂时已被解决

@bob-lytton 其实你提醒了我一个错误 orz ... OperationFailedError 这个类确实是写错了一个地方 ...

关于你遇到的验证码不能识别的问题，我个人觉得是因为选课网的问题

[INFO] loop, 15:29:36, Course(操作系统A, 1, 信息科学技术学院, 180 / 0) is AVAILABLE now !
[INFO] loop, 15:29:36, Course(数理逻辑, 1, 信息科学技术学院, 260 / 0) is AVAILABLE now !

我前段时间很偶然地遇到过这种课程已选人数突然降为 0 的问题，它非常罕见。应该下一个回合发回来的包就是对的。

simplejson.errors.JSONDecodeError: Expecting value: line 5 column 1 (char 8)

这个错误是因为对方发回来的 response body 不是 JSON 格式，很有可能是发了一个网页回来，应该会带有一个错误提示（我曾经遇到过未同意选课协议的提示）。

我觉得这可能就是一个选课网的偶发错误，可能它正在更新数据或者重启应用啥的 ... 但是因为没有 dump request ，当时的情况也复现不了了，我也就只能猜测到这个程度了 ...
