A Strange angular prod build issue

Solution:

ncu -u

npm remove webpack

npm install webpack@3.11.0

Scenario:

ng build --prod

@angular/compiler-cli@5.2.9 requires typescript@'>=2.4.2 <2.7.0' but 2.8.1 was found instead.

Using this version can result in undefined behaviour and difficult to debug problems.

Please run the following command to install a compatible version of TypeScript.

    npm install typescript@'>=2.4.2 <2.7.0'

To disable this warning run "ng set warnings.typescriptMismatch=false".

  0% compiling

An error occured during the build:
