I used following command to create new angular project
ng new hello-world
It failed showing
npm WARN deprecated circular-json@0.5.9: CircularJSON is in maintenance only, flatted is its successor.
npm ERR! Unexpected end of JSON input while parsing near '...rocess":"~0.7.0"},"_h'
Then I installed flatted using...
npm i flatted
But the error still occurs. How to use flatted instead of deprecated library circular-json?
Run following commands that will clean NPM cache
npm cache clean --force
after this run following command
npm install -g @angular/cli@latest
then you can create angular project.
If it doesn't work, even after clearing the cache, which happened in my case:
Make sure you try the ng new create-app command using Powershell in administrator mode.
This worked for me.
I had the same problem. None of the above mentioned answers worked for me.
So I removed the content of .npmrc, ran the generate command and it worked.
After that, you can restore the content of your .npmrc if needed.
