Mention any other details that might be useful.

I'm using yarn and have performed a clean re-install of angular-cli (yarn remove && yarn add) for the upgrade from .beta-21 to .beta-22 so that all indirect dependencies are on their latest version as well. However, running a yarn check (checks the integrity of all specified version dependencies) yields this error:

iDevBook01:console jr$ yarn check
yarn check v0.17.10
error angular-cli#tslint-loader#tslint@^3.0.0 doesn't satisfy found match of [email protected]
warning chokidar#fsevents#node-pre-gyp@^0.6.29 could be deduped from 0.6.31 to [email protected]
error Found 1 errors.

So it seems angular-cli maybe needs an upgrade of tslint-loader in its package.json?

[JohannesRudolph]

Did some more digging, it appears tslint-loader resolves to version 2.1.5 for me (angular-cli's package.json specifies ^2.1.4, which has the following package.json:

  "name": "tslint-loader",
  "version": "2.1.5",
...
  "peerDependencies": {
    "tslint": "^3.0.0"
  },
}

So looks like we need an update of tslint-loader (its 3.x series supports tslint 4.0). So I have done a yarn add tslint-loader --dev and alas, my issue is fixed and ng test --lint works as it should.

Same problem with UNMET tslint dependency addressed in #3453
