从Webpack 3迁移到Webpack 4 [英] Migrating to Webpack 4 from Webpack 3

问题描述

我正在尝试迁移到Webpack 4，但这真的很痛苦。在将Webpack 3插件移动到Webpack 4原生内容之后的几天，我得到 js ，据说可以正常呈现，但是当我访问我的网站时，我收到了这条消息在控制台上：

I am trying to migrate to Webpack 4, but is has been a real pain. After couple of days working on moving Webpack 3 plugins to Webpack 4 native stuff, I got the js to be rendered fine supposedly, but when I go to my website I got this message on the console:

未捕获TypeError :(中间值）（中间值）.push不是函数

开：

（window [webpackJsonp] = window [webpackJsonp ] || []）。push（[[Index]，{

这是我的Webpack 输出设置：

This is my Webpack output settings:

output: {
    filename,
    path: path.resolve(__dirname, 'public', 'build', 'js'),
    jsonpFunction: 'webpackJsonp', // TODO gotta figure that out
},

我做错了什么？

推荐答案

刚刚遇到同样的问题我找到了这个帖子 https://github.com/webpack / webpack / issues / 6985

Just had the same issue and I have found this thread https://github.com/webpack/webpack/issues/6985

当您将模块与 Webpack 捆绑在一起时，似乎会发生这种情况。 4.如果有任何帮助，我会在这里张贴。

It seems to happen when you have modules bundled with Webpack < 4. I'm posting it here if it can be of any help.

更改 output.jsonpFunction < a href =https://webpack.js.org/configuration/output/#output-jsonpfunction =nofollow noreferrer> https://webpack.js.org/configuration/output/#output-jsonpfunction 到 jsonpFunction 解决了它：

{
  output: {
    jsonpFunction: 'jsonpFunction',
    ...
  }
}
