我有一个金字塔项目，在使用 development.ini 托管时可以正常工作，但是一旦我使用 production.ini，我就会在浏览器中收到此错误：

Internal Server Error
The server encountered an unexpected internal server error
(generated by waitress)

这个登录终端：

我复制了.ini 文件中的部分sqlalchemy.url和部分，但看不到导致此错误的原因。mako.directories[app:main]

我启动服务器：../bin/pserve/production.ini --reload

我错过了什么？

这是因为最新版本的 Pyramid 默认不需要/安装 Mako 的模板引擎。要修复此错误，如记录的HERE，您必须做两件事：

  1. 确保pyramid_mako已安装软件包。一种方法是将“pyramid_mako”添加到install_requires包setup.py文件的部分，然后重新运行setup.py develop：

    setup(
    #...
    install_requires=[
        'pyramid_mako',         # new dependency
        'pyramid',
        #...
    ],
)

  2. main()在实例化 Pyramid 配置器（通常是项目文件中的函数）的应用程序部分中__init__.py，告诉 Pyramid 包含包含pyramid_mako：

    config = Configurator(.....)
config.include('pyramid_mako')
