- `@testing-library/react`: 11.2.5

- Testing Framework and version: jest at 26.6.3

  <!-- are you using jest, mocha, puppeteer, ava? And what version? -->

- DOM Environment: jsdom at 11.12.0

  <!-- If you're using jsdom (the default with jest), what version? Otherwise, what browser and version are you running tests in? -->



<!--

Keep in mind that if you're using a version of node we don't support that

could also be an issue. Check our package.json file "engines" config for the

supported version.



Also keep in mind that if you're using a version of react we don't support

that could be an issue. Check our package.json file "peerDependencies" config

for the supported version.

### What you did:



install "@testing-library/react": "^11.2.5" via adding directly in package.json and `lerna bootstrap`.



### What happened:



> Cannot read file '.../node_modules/@testing-library/react/node_modules/kcd-scripts/shared-tsconfig.json'.



<!-- Please provide the full error message/screenshots/anything -->



### Problem description:



A dependency of react-testing-library is not being installed. In react-testing-library's package.json:



```json

 "eslintConfig": {

    "extends": "./node_modules/kcd-scripts/eslint.js",

```



So my editor now requires the existance of that eslint.js file.



### Suggested solution:



Add the missing kcd-scripts in dependencies of react-testing-library.



When I install `kcd-scripts` alongside `@testing-library/react` in my package devDependencies (and restart TS server in vs code), then the error goes away. But I would expect that the expected behaviour is to just install `@testing-library/react` and not get the error in the first place 🙂
