'compilation' 参数必须是 Compilation 的实例

The 'compilation' argument must be an instance of Compilation

在我的 Angular 12.0.2 项目 运行 'ng build' 上出现此错误

./src/polyfills.ts - Error: Module build failed (from ./node_modules/@ngtools/webpack/src/ivy/index.js):

我一直在谷歌搜索,但找不到任何可以解决我的问题的方法。我不确定是什么触发了这个。

我们想通了。正如您在我们的 packages.json 中看到的,我们依赖于 webpackangular-devkit/build-angular 似乎也是如此。我们认为这造成了多个 webpack 冲突并导致问题的已知问题。删除我们对 webpack 的依赖解决了这个问题。

是的,这个问题与 2 个不同的 webpack 库有关。 要解决添加到您的 package.json 下一个块的问题:

 "resolutions": {
        "webpack": "5.41.1"
    },

在我的例子中,这是错误的路径。

我 运行 来自 git Bash 的命令有错误的驼峰式字母。

赞:c://Dev/Product 而不是:c://dev/Product

修复了路径并且它有效。

我在 Angular 13 的“运行 ng”测试中遇到了类似的问题。

"devDependencies": {
    "@angular-devkit/build-angular": "13.3.0", // requires webpack 5.70.0 

这通常发生在 webpack 是多个包的依赖项时。锁定 package-lock.json 并搜索“webpack”依赖项是我的方法。 “npm dedupe”有时可以解决此类问题。
