python如何在注释上生成错误？

Question

我已经摆好了a question about this a few days ago。我想这个问题没有被注意到，但行为确实很奇怪，所以我试图把它简化为更简单的元素，然后再问一次。在

请看这个回溯：

第159行怎么会产生这样的错误？是评论！

目前所做的努力： 在查询生成此错误的视图之前，我已经删除了所有.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）。在

有什么想法吗？在

更新： 通过安装并重新安装所有的解释器来解决问题。但是没有更新库，所以我仍然不明白到底发生了什么。在
