in Angular 6.1.8 : I suddenly got this error : Cannot find module './populate-components'

Question

I'm working on a Angular 6.1.8 project with cli 6.2.2 and I suddenly got this error when trying to 'serve' or 'build' with the ng command:

Cannot find module './populate-components'
Error: Cannot find module './populate-components'

I say suddenly because I really had the impression to change nothing... I really even don't know where to look, I'm stuck... (not so confident in web development :-/)

If you have any clue, thx !

Answer 1

似乎失去了依赖性。 确保您的依赖项已正确注册到 let array = []; text.subjects.forEach(subject => ( let obj = {}; obj.code = subject.code; obj.description = subject.description; array.push(obj); ));

中

package.json

然后检查您的组件在npm install populate-components --save中已声明

app.module.ts

Answer 2

好的，我找到了解决方案... 仅在“ clean-css”节点模块中引用了populate-modules。 因此，我已经删除了该模块的文件夹，然后再次运行“ npm install”。 现在可以了....
