Question

我卸载了webpack并删除了webpack.config.js文件，以便我可以将express.js与Heroku一起使用。提交并推送到heroku后，我的日志如下：

$ heroku logs
2017-09-10T17:42:43.224045+00:00 heroku[web.1]: State changed from crashed to starting
2017-09-10T17:42:02.000000+00:00 app[api]: Build succeeded
2017-09-10T17:42:47.480825+00:00 heroku[web.1]: Starting process with command `node ./node_modules/webpack-dev-server/bin/webpack-dev-server.js`

2017-09-10T17:42:50.050108+00:00 app[web.1]:     throw err;
2017-09-10T17:42:50.050108+00:00 app[web.1]:     ^
2017-09-10T17:42:50.050109+00:00 app[web.1]: 
2017-09-10T17:42:50.050110+00:00 app[web.1]: Error: Cannot find module '/app/node_modules/webpack-dev-server/bin/webpack-dev-server.js'

日志中的启动过程是尝试启动webpack ^，但在我的Procfile中我有这个：

web: node server.js

要确认，这里是heroku ps

$ heroku ps
=== web (Free): node server.js (1)
web.1: up 2017/09/10 14:41:56 -0400 (~ 27m ago)

的package.json：

    "react-redux": "^4.0.0",
    "redux": "^3.0.4",
    "youtube-api-search": "0.0.5"
  }
}

server.js：

var express = require('express');
var app = express();
var path = require('path');

app.use(express.static(path.join(__dirname)));
app.use("/style", express.static(__dirname));

// viewed at based directory http://localhost:8080/
app.get('/', function (req, res) {
  res.sendFile(path.join(__dirname + 'index.html'));
});

app.listen(process.env.PORT || 8080);

heroku更新需要时间吗？发生了什么事？

当我使用express.js时，为什么Heroku运行webpack进程？
