Question

编译时出现错误。对于webpack中的ProgressPlugin似乎不满意：

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

TypeError: Cannot read property 'tap' of undefined

我知道webpack 4的插件最近进行了一些更改。看来addEntry, failedEntry, succeedEntry不在编译挂钩的文档中-https://webpack.js.org/api/compilation-hooks/-我是否缺少某些内容？

我的package.json deps：

Answer 1

您有2个不同版本的webpack，您安装的版本导致其崩溃。

不要自行安装webpack，因为它已经安装了next。

Answer 2

在我的情况下，错误是我将插件放在resolve.plugins下，而不是直接在webpack配置中的plugins下。来自https://github.com/webpack/webpack/issues/8548#issuecomment-449829774

的解决方案

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

ProgressPlugin TypeError：无法读取未定义的属性“ tap”
