ProgressPlugin TypeError:无法读取未定义的属性'tap‘

Question

我在编译过程中遇到一个错误。看起来对webpack的ProgressPlugin不太满意：

/node_modules/webpack/lib/ProgressPlugin.js:205
    compilation.hooks.addEntry.tap("ProgressPlugin", entryAdd);

TypeError: Cannot read property 'tap' of undefined

我知道最近对webpack 4的插件进行了一些更改。似乎编译钩子- https://webpack.js.org/api/compilation-hooks/的文档中没有addEntry, failedEntry, succeedEntry -我是不是遗漏了什么？

Answer 1

你有两个不同版本的webpack，你安装的那个会导致它崩溃。

不要自己安装webpack (从package.json上删除它)，它已经和next.js一起安装了

Answer 2

在我的例子中，错误是我在resolve.plugins下放了一个插件，而不是直接放在webpack配置中的plugins中。解决方案来自：https://github.com/webpack/webpack/issues/8548#issuecomment-449829774

Answer 3

这是因为不同的webpack。尝试运行此命令。

npm install --save-dev webpack@4.44.0
