烧瓶：ImportError：没有名为folder.file的模块

Question

我有一个基于 Atlantis Dashboard 的烧瓶应用程序。

使用以下命令在 Windows 上运行良好：

• flask run --host=0.0.0.0 --port=5000。

现在我正在尝试在 Linux 服务器上部署它，我克隆了项目并尝试启动它：

• flask run
• py -m app.app
• waitress-serve --port=8001 run:app
• 试图更改导入语法
• .. 再进行 20 次试验

但是做不到！我不断收到错误消息：

* Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
Usage: flask run [OPTIONS]

Error: While importing "app", an ImportError was raised:

Traceback (most recent call last):

    from secret.keys import SECRET
ImportStringError: import_string() failed for 'app.configuration.Config'. Possible reasons are:

- missing __init__.py in a package;
- package or module path not included in sys.path;
- duplicated package or module name taking precedence in sys.path;
- missing module, class, function or variable;

Debugged import:

- 'app' found in '/var/www/project_x/app/__init__.pyc'.
- 'app.configuration' not found.

Original exception:

ImportError: No module named secret.keys

项目结构：

project_x
- app
   - __pycache__
   - __init__.py
   - configuration.py
   - api.py
   - static
   - templates
   - secret
        - keys.py
- run.py

我做错了什么？为什么 Linux 不一样？？
