Question

我有一个金字塔项目在使用development.ini托管时工作正常，但是一旦我使用production.ini，我在浏览器中出现此错误：

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

并登录终端：

ValueError: No such renderer factory .mak

我复制了.ini文件中sqlalchemy.url部分下的mako.directories和[app:main]，我无法看到导致此错误的原因。

我使用：../bin/pserve/production.ini --reload

启动服务器

我错过了什么？

这是因为最新版本的Pyramid默认情况下不需要/安装Mako的模板引擎。要解决此错误，请记录HERE，您必须做两件事：

确保已安装pyramid_mako包。一种方法是将“pyramid_mako”添加到软件包install_requires文件的setup.py部分，然后重新运行setup.py develop：
```
setup(
    #...
    install_requires=[
        'pyramid_mako',         # new dependency
        'pyramid',
        #...
    ],
)
```
在应用程序中实例化Pyramid配置程序的部分（通常是项目的main()文件中的__init__.py函数），告诉Pyramid包含pyramid_mako includeme：< / p>
```
config = Configurator(.....)
config.include('pyramid_mako')
```

使用production.ini托管金字塔应用程序时出现服务器错误
