ng lint Could not find custom rule directory: codelyzer with Angular CLI on gitlab CI

Question

ng lint fails on Gitlab CI with the error message An unhandled exception occurred: Failed to load /builds/trade-up/trade-up/common/projects/trade-up-common/tslint.json: Could not find custom rule directory: codelyzer.

ng lint is running without issues on my local machine but failing on gitlab CI.

In the trade-up-common package, I have added tslint.json to the .npmignore file. Codelyzer is included in the dependencies of both the main angular app and the common package.

Answer 1

You have to install codelyzer

npm install codelyzer

then define in the rules directory :

 "rulesDirectory": [
    "node_modules/codelyzer"
  ],

---

UPDATE:

If your tslint.json is different, try this:

"rules": {
    "directive-selector": [
        "codelyzer"
    ],
