Missing module @typescript-eslint

[Martinspire]

I'm getting an error after running the schematic ng add @angular-eslint/schematics:

npm ERR! code ENOENT
npm ERR! syscall rename
npm ERR! path D:\Projects\simulator\ui\node_modules\@typescript-eslint\experimental-utils\node_modules\eslint-scope

Package install failed, see above.

Which is probably because @typescript-eslint isn't installed. There is no reference to this in the readme either.

After running npm install -D @typescript-eslint/parser @typescript-eslint/eslint-plugin @typescript-eslint/typescript-estree it worked.

I'm not sure whether it should be part of the schematic or whether I missed something installing the project, but something is missing somewhere...

Hmm it's a good point, I was approaching it from the point of view of giving users flexibility to choose their typescript-eslint version, but we do need to address this, either through docs or changing what we install...

Open to community suggestions and solutions here!

Personally, as someone who is not geeking out over linting but just wants to set something up that works and move on, I would prefer having the schematic install the packages that @Martinspire installed.

As of v0.0.1-alpha.31, ng add @angular-eslint/schematics installs absolutely everything you need to run linting with ESLint on an Angular workspace.

Next up will be a schematic for adding ESLint configuration to an existing project
