对于 package.json

我在本地测试,应用程序使用 express 在端口 5000 上运行
var express = require('express'),
app = express();
app.use(express.static('www'));
// CORS (Cross-Origin Resource Sharing) headers to support Cross-site HTTP requests
app.all('*', function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "X-Requested-With");
next();
});
// API Routes
// app.get('/blah', routeHandler);
app.set('port', process.env.PORT || 5000);
app.listen(app.get('port'), function () {
console.log('Express server listening on port ' + app.get('port'));
});
最佳答案
我在这里看到了一些问题
1) 你需要一个procfile - https://devcenter.heroku.com/articles/getting-started-with-nodejs#define-a-procfile
2) 您没有在 package.json 中指定引擎
"engines": {
"node": "0.10.x"
},
请参阅此处- https://discussion.heroku.com/t/the-official-node-js-buildpack-is-going-on-a-diet/100
3) 你已经将你的 node_modules
目录提交给了 git。您应该能够使用 npm install
下载软件包(这就是您的 packages.json
文件的用途)
删除这个目录,并将删除提交给git。
然后,创建一个 .gitignore
文件。将以下行添加到您的 .gitignore
文件中:
node_modules
将此 .gitignore 文件提交到您的存储库。
Git 现在将忽略您的 node_modules_
目录
