Angular-cli: typescript 2.8.3

[bbuehrer]

Is it compatible with typescript 2.8.3 ?

@bbuehrer With me give not compile first time and after a change work well.
https://github.com/angular/angular-cli/issues/10836

It is suggest typescript version:
The Angular Compiler requires TypeScript >=2.7.2 and <2.8.0

I have also

ERROR in The Angular Compiler requires TypeScript >=2.7.2 and <2.8.0 but 2.8.3 was found instead.

Angular and cli are up-to-date versions.

Same here.
It would be nice to have this error downgraded to a warning. It seems to be a bug in the build process more than anything else. As of right now its holding us back from upgrading to Angular 6.

The Angular AOT Compiler v6.0.x only officially supports TypeScript 2.7.x. Using any other version is not guaranteed to function properly. However, if using TypeScript 2.8 is preferred, the error can be disabled by using the disableTypeScriptVersionCheck option within angularCompilerOptions inside the application's tsconfig.

@clydin :
Error: tsconfig.json(11,5): error TS5023: Unknown compiler option 'disableTypeScriptVersionCheck'.

Worked for me. Make sure that you set it in tsconfig.app.json and not tsconfig.json.

"angularCompilerOptions": {
    "disableTypeScriptVersionCheck": true
}

Example of an augmented new project application's config:

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "es2015",
    "types": []
  },
  "exclude": [
    "src/test.ts",
    "**/*.spec.ts"
  ],
  "angularCompilerOptions": {
    "disableTypeScriptVersionCheck": true
  }
}

Might also want to run ng config cli.warnings.typescriptMismatch false to silence the warning as well.

Ok, i set it in the tsconfig.app.json and it work.
Thanks
