@jnachman123 I had the same issue when using node version 16.13.

Switched back to node version 14.17 and it worked first time 👍

Also having this issue with Node v16

I am also having following error

I have tried to use node version 14.17.0 and also tried 14.17.3.

Is there any specific 14.17. something version required?

This is part of npm v7 shipping with Node v16. To add previous behaviour you'll need to do npm install --legacy-peer-deps.

This worked for me! To avoid having to reinstall node, you can use a node version manager. (https://stackoverflow.com/questions/7718313/how-to-change-to-an-older-version-of-node-js/50817276)

Then run:

1. n 14.17
2. n exec 14.17 npm install
3. n exec 14.17 npm start

@vcoopman or just run npm with --legacy-peer-deps

[yashvantvala]

I have make it work with skipping the dev dependencies, If you remove dev dependencies from the package.json then it will work with most of nodejs version

@vcoopman or just run npm with --legacy-peer-deps

I tried with that using node 17, but no luck

Try to remove dev dependecies from package.json

Try to remove dev dependecies from package.json

This was the only thing that worked for me.
