我有一个非常基本的风帆应用程序并在本地运行.当我部署到Heroku时,我无法从应用程序获得响应,然后最终得到“应用程序错误”.我有时收到“没有收到数据”.

解决方法
您还可以为Heroku使用专门的buildpack,在部署时运行Grunt任务,然后在Sails中为生产环境关闭Grunt.这是一个更多的工作,但它可能是必要的,因为Heroku有自己的超时,可以被Grunt花费太长时间来摧毁你的资产.
我们已经成功使用了heroku-buildpack-nodejs-grunt.您可以按照说明在Heroku应用程序上安装它,然后将任务定义复制到tasks / register / prod.js中以包含heroku：生产任务,例如：
module.exports = function (grunt) {
grunt.registerTask('prod',[
'compileAssets','concat','uglify','cssmin','sails-linker:prodJs','sails-linker:prodStyles','sails-linker:devTpl','sails-linker:prodJsJade','sails-linker:prodStylesJade','sails-linker:devTplJade'
]);
grunt.registerTask('heroku:production','sails-linker:devTplJade'
]);
};
然后最后在你的app.js文件中,替换
sails.lift(rc('sails'));
有：
var config = rc('sails');
if (process.env.NODE_ENV === 'production') {
config.hooks = config.hooks || {};
config.hooks.grunt = false;
}
// Start server
sails.lift(config);
