使用 Emperor 将目录中的文件提供给 uWSGI Flask 应用 运行
Serving files in directory to uWSGI Flask apps run with Emperor
我更改了我的 uWSGI 设置以使用 Emperor 进行多应用程序部署。使用旧设置加载保存在我的应用程序旁边的 'mypasswords.pwds' 文件时，没有问题。
现在 运行 Emperor 的所有内容我都会遇到 'No such file or direcotry' 错误。这可能是因为我的设置，或者因为 Emperor 只是以不同的方式工作，我不确定是怎么回事。

你原来的方法是使用相对位置，所以如果你不在项目文件夹中，可能找不到文件。此外，使用 with 块是处理文件的更好方法，它将确保在退出上下文块时关闭文件。
