Angular version 6.1.0 support typescript 2.9. But when I change typescript dependency in package.json. This warning is shown.

@angular/[email protected] requires typescript@'>=2.7.0 <2.8.0' but 2.9.2 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@'>=2.7.0 <2.8.0'

To disable this warning run "ng config cli.warnings.typescriptMismatch false".

Desired functionality

Serve correctly without showing the warning

Mention any other details that might be useful

versionCombos variable in node_modules/@angular/cli/upgrade/version.js seem not being built correctly. The codes in upgrade/version.ts file seem correct.

   As I recall from the last time there was such an upgrade, for various legacy reasons the compatibility version check is implemented in CLI, with the code of that understands the version relationship compiled into CLI (or dev kit). So they will need to be a CLI update to understand that a new range of Angular versions is compatible with the new range of TypeScript versions.

   So we are just a bit patient, likely the next new CLI version should understand the new versions, and contain any other needed tweaks to make it all run smoothly.

   @sundarchi1 Yes, it does fix the issue when you already upgraded to TypeScript 2.9. The issue you've just raised is a separated issue in which Angular CLI generates TypeScript 2.7 as default.

   As for that issue, #11669 is pending.

   Although this is probably not a big problem, I see that @schematics/[email protected] still has a dependency on typescript < 2.8. It installs a separate copy of typescript, so it is compatible with global typescript in version 2.9.
