Tried above methods but returns some WAR and ERR

Thanks in ADVANCE

Answer 1

It looks like the npm modules used as dev dependencies are outdated. That's why you get the WARN messages.

Regarding the ERR, there might be no release with version 2.6.0 available anymore for the accessibility-developer-tools. Modify it's version in your package.json file to 2.10.0 (latest version at this moment) and see if it works.

Update

After fiddling with the package.json you provided, I wasn't able to make the npm install --only=dev work on my linux machine due to about 938475938475 errors I kept getting.

I noticed that the mean version you use is 0.4.0 which is quite old. I recommend you to use the current version, by following the installation steps from the original repository

After I issued the npm install on the cloned repository and after it installed what appeared to be the whole npmjs ecosystem, the app worked.

Hope this helps.
