Webstorm and VisualCode complaining about the new Matchers

[gpeel]

Starting with a fresh new Angular 14 project and following instruction to install karma-jasmine-matchers enable correct execution of tests but the 2 IDEs complains about the added matchers.

the code is availlable at URL

Hi @gpeel, my answer is a little broad and vague just because I don't have much information to work with so far. How does your setup compare to the instructions here? If it matches, what versions are you using?

[gpeel]

Hi
well I followed exactly those instructions
And also in the last line of the the preceding post, I give access to a full code in github to check what I did.
Here it is:
https://github.com/gpeel/test-adding-jasmine-matchers

So my conclusion so far is that there seems to be something missing from those insctructions.
since starting afresh with a new project does not work.
I tries to change a few things but never was able to make it work

I found a way to solve the problem by adding those lines in tsconfig.json

    "typeRoots": [
      "./node_modules/@types",
      "./node_modules/jasmine-expect/dist"
    ]

Or another solution, to add
/// <reference types="jasmine" />
at the top of the test file. Then the IDE find the definitions

But looking at the file ./node_modules/jasmine-expect/package.json the types property is already set to dist/index.d.ts
So it should work automatically, but it doesn't.

Any idea why ?
