python - python如何在评论中产生错误？

Question

我已经摆好了a question about this a few days ago .我想这个问题没有引起注意，但行为真的很奇怪，所以我试图将它简化为更简单的元素并再次询问。

请看这个回溯:

Traceback (most recent call last):

    raise GEOSException("Calling transform() with no SRID set is not supported")

第 159 行怎么会产生这样的错误？是评论!

到目前为止尝试了什么: 在查询生成此错误的 View 之前，我删除了所有 .pyc 文件并重新启动了 gunicorn。在源代码 (django-geojson lib) 中没有对 transform() 函数的其他调用(我对它们都进行了注释)。

有什么想法吗？

更新: 我能够通过卸载然后重新安装所有库(作为 ubuntu 包)、python 解释器、所有代码、重新生成数据库(包括重新安装 postgis)然后完全重新启动 nginx(和因此 gunicorn)。但是，没有更新任何库，所以我仍然不明白到底发生了什么。
