Error on npm install

[gopala000]

I want to try the sample vue app to use with identity server. When I run npm install, I get the following error. How to I get around with this? Thanks

I've fixed it so it doesn't have this error on npm v7, but this repo was made using yarn so not sure how well it really works.

Thanks, @soukoku. That error is fixed. Now, when I run the server using npm run serve, I get below error:

C:\Users\foo\source\repos\vue-oidc-client\sample>npm run serve
