Sails.js 应用程序无法在 heroku 上部署

Question

我的sails.js 应用程序在本地主机上运行良好，但在heroku 上失败。

我的 production.js 中有以下设置

  port: process.env.PORT || 1337,
  environment: process.env.NODE_ENV || 'development',

仍然收到以下消息并且部署失败；

请指教，谢谢。

Answer 1

您的应用正在生产模式下运行。因为Forcing Waterline to use `migrate: "safe" strategy (since this is production) 和 concat/uglify 任务正在运行，我可以说出来。

这个进程（concat/uglify）可能正在破坏分配的内存。在需要处理大量 js/css 的小型 heroku 实例上部署时，我已经看到了这一点。您可能想尝试 https://github.com/mbuchetics/heroku-buildpack-nodejs-grunt 在部署而不是启动时运行 grunt。

请参阅http://blog.mdarveau.com/2014/10/20/deploying-to-heroku，了解我在 Heroku 上部署 Sails 应用程序的经验。

日志中的以下部分很奇怪：

Answer 2

在 config/models.js 中设置 migrate: 'alter'

Answer 3

快速（临时）解决方案只是删除生产标志

delete process.env.NODE_ENV;
