Docker和Zappa:错误的python路径

Question

我正在尝试使用Zappa和Docker在Lambda中运行Django，我正在遵循outlined here的说明。

当我运行zappa deploy dev时，我一直收到下面的FileNotFound错误。看起来我的pythonpath和虚拟环境路径是错误的，我不知道它是如何进入的。我尝试在Dockerfile中设置pythonpath，但没有成功。

问题是我最初有两个虚拟环境，一个是现有的，另一个是为Docker新创建的。解决方案是从Dockerfile中删除PYTHONPATH变量，删除两个虚拟环境并创建一个新环境。
