AnguIar incompatible peer dependencies found

Question

I ran an angular project today, and it told me it had a lot of low vulnerabilities and a few high ones. so I typed: *ng update @angular/core @angular/cli *ng update

but now when I try to run it, it gives me these errors:

Error: ./src/main.ts
Module build failed (from ./node_modules/@ngtools/webpack/src/ivy/index.js):
TypeError: angularCompiler.getDiagnosticsForFile is not a function
    at C:\.....\Angular\node_modules\@ngtools\webpack\src\ivy\plugin.js:384:60

Have you tried the other solutions to this [question](https://stackoverflow.com/questions/65849026/errors-after-npm-audit-fix-angular-10-0-1), namely deleting node_modules and reinstalling and building — Andrew Allen, May 12 '21 at 00:37
You are basically your angular version with `ng update` command. You should follow their official guidelines to update angular version. https://update.angular.io/ — Mir entafaz Ali, May 12 '21 at 05:42

I upgraded my app to Angular 11 and had same build errors. This issue fixed for me when I downgraded below package in package.json file.

From:

"devDependencies": {
"@angular-devkit/build-angular": "~0.1102.17",
}

To:

"devDependencies": {
"@angular-devkit/build-angular": "~0.1100.2",
}
