我在编译项目时收到下面给出的错误。

Generating browser application bundles (phase: setup)...Options:

                                         Each of these properties should hold
                                         the path to a bundle-format.

                                         module) in the package.json are

可以指导我如何解决这个问题吗？

Answer 1

运行此命令 npm i @ngtools/webpack 并在 @ 之后提及您想要的版本，与您的 Angular 版本相同。

npm i @ngtools/webpack@9.1.15

无论您使用的 Angular 是什么版本，都选择相同的版本。

Version              Downloads (Last 7 Days)             Tag
12.2.14                           101,188               v12-lts
8.3.29                             60,775               v8-lts
9.1.15                             57,568               v9-lts
7.3.10                             34,584               v7-lts

你可以在这里找到所有的包@ngtools/webpack

Answer 2

我对 Angular 12 和 Node 17.4.0 也有类似的问题。我将 Node 更改为 v16.13.2，现在它工作正常。
