我在编译过程中遇到一个错误。它似乎对webpack:中的ProgressPlugin不满意
/node_modules/webpack/lib/ProgressPlugin.js:205
compilation.hooks.addEntry.tap("ProgressPlugin", entryAdd);
TypeError: Cannot read property 'tap' of undefined
我知道webpack4的插件最近有一些变化。addEntry, failedEntry, succeedEntry似乎不在编译挂钩的文档中-https://webpack.js.org/api/compilation-hooks/-我是不是错过了什么？
我的包.json deps:

在我的例子中，错误是我在resolve.plugins下放置了一个插件，而不是直接在webpack配置中的plugins中。解决方案来自：https://github.com/webpack/webpack/issues/8548#issuecomment-449829774
您有两个不同版本的webpack，您安装的那个版本会导致它崩溃。
不要自己安装webpack(从package.json中删除(，它已经安装在next.js 中了
这是因为不同的webpack。尝试运行此命令。
npm install --save-dev webpack@4.44.0
有点像一个旧线程，不一定是上面问题的解决方案，但我有冲突的包，通过解决了它
- 还原package-lock.json和package.json中的更改
- 运行npm-ci
它将删除node_modules目录，并根据您的package-lock.json文件安装软件包
