解决方案
将webpack依靠将你的 Heroku slug 从devDependencies构建到你的包中的dependencies .json。
您应该可以使用普通的webpack而不是./node_modules/.bin/webpack来调用它。
默认情况下，devDependencies仅安装在开发平台上的node_modules中，而Heroku被定义为生产平台。
Judging from other topics (none which helped me), this seems to be a reoccurring issue, I am trying to deploy my app to heroku. It works fine with heroku local web, I have deployed the app and git heroku push to the master but as soon as I run heroku open, nothing loads and I get the following error:
Application error An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details.
I checked my logs and it says:
Error: Cannot find module 'webpack'
My Package JSON has the following dependencies:
"dependencies": {
"babel-runtime": "^6.20.0",

What do I have to do to get it running on heroku? Do you need to install webpack on the server?? How does this work

解决方案
Move webpack (and any other tools you rely on for building your Heroku slug from "devDependencies" to "dependencies" in your package.json.
You should also be able to call it with just plain "webpack" instead of ./node_modules/.bin/webpack.
By default, "devDependencies" only get installed in node_modules on Dev platforms, whereas Heroku is defined as a production platform.
