Sails js 和 Heroku：应用程序发生错误，无法提供您的页面。

Question

我需要有关 heroku 的帮助。我的应用程序运行良好，但今天无法运行。我没有修改任何文件。有人可以帮助我吗？我在 stackOverFlow 中关注了另一个帖子，但没有用。

我运行 heroku 日志：

我运行 npm install，再次 git heroku push 但没有发生。 谢谢。

Answer 1

你需要做更多的工作来准备在 Heroku 上运行的风帆。首先，Sails 有一个固有的构建过程。默认情况下，当您推送到 Heroku 时，NODE_ENV 环境变量设置为 production。这将导致npm 不加载任何开发依赖项。查看这是否是唯一错误（我不确定是不是）的最快解决方法是将您的NODE_ENV env 变量设置为staging（或其他任何东西，只要它不是production）并尝试再次推动。这应该会加载您的开发依赖项，并且可能会让您走得更远。

最终，如果您要在 Heroku 上为 Sails 提供服务，您需要找到一种更好的部署方式。我建议查看这个heroku-sails 示例和包：https://github.com/chadn/heroku-sails

Answer 2

当我将sails.js 应用程序部署到heroku 时，我通常至少会执行以下操作 -

1. 在您的 .sailsrc 文件中 - 您需要关闭 grunt（在进行本地开发时，将其注释掉）-

   {"generators": {"modules": {}},"hooks": {"grunt": false}}

2. 然后，当 NODE_ENV 为 prod 时，您将需要配置静态资产以从编译目录加载，因此在 /config/env/production.js - 将变量添加到您的导出中 -

   路径：{public:__dirname+'/../../www/'}
