JSON CMS 中的 ValueError，龙卷风
JSON ValueError in CMS, tornado
我正在尝试 运行 竞赛管理系统 (docs) Ubuntu 16.04。
CMS 运行 很好，但有时会 returns 错误，简而言之：
ValueError: No JSON object could be decoded
怕在package中修改代码会出错，所以请避免这种方法。
这是错误信息
在 cmsAdminWebServer 中：
2016/08/19 22:39:55 - ERROR [AdminWebServer,0] Cannot decode score type parameters.
ValueError('No JSON object could be decoded',).

对不起，是我的失误。
对于谁有同样的错误，（预计没有人）
我填写的任务评分表不正确，因此 JSON 无法对其进行解码。
关闭！
