我在使用var webpack = require('webpack')

调用server.js的第一行调用node server.js

我删除了node_module; rm -rf node_module npm install了。仍面临同样的问题。

答案 0 :(得分：7)

这更像是一个麻烦的答案，但这个问题通常会出现两个问题之一：

  1. webpack是全局安装的（在某些时候你做了npm install webpack -g）
  2. webpack作为devDependency安装。

    3. 如果您运行的服务器需要webpack，则您需要将其安装为dependency。

    如果您没有使用任何服务器端中间件，那么将webpack设置为devDependency通常就是您想要的。

我对使用create-react-app创建的应用程序存在相同的问题，并且解决了该问题，我去了Heroku中的应用页面的Settings标签，然后进入了Builpacks我添加的部分是：https://buildpack-registry.s3.amazonaws.com/buildpacks/mars/create-react-app.tgz作为构建包。
