gunicorn ImportError：没有名为webob的模块

Question

我通过使用以下命令运行一个appengine项目：

gunicorn -b $3000 main:app

这是一个python（Django）项目，我正在linux上运行它。

确切的错误是：

我有webob，但我不知道为什么会收到此错误。我试图点安装webob。

Answer 1

在使用appengine时，必须在app.yaml中的libraries指令下指定它

libraries:
- name: webob
  version: "1.1.1"

检查文档：https://cloud.google.com/appengine/docs/standard/python/tools/using-libraries-python-27使用与运行时捆绑在一起的内置第三方库。
