i have uninstalled angular
and trying to install latest version
“npm install -g @angular/cli@latest”
but same error
npm ERR! Unexpected end of JSON input while parsing near ‘…“console-group”:"^0.3’
it’s seem a problem installing dependencies maybe npm, try:
npm cache verify
EDIT (sorry):
npm cache clean --force
After try, again. maybe if you have “package.lock.json” delete it and try again.
I am not using any “package.lock.json”
trying to install angular
here is the result of npm clear cache --force
G:>npm clear cache --force
npm WARN using --force I sure hope you know what you are doing.

the only solution i found on npm but this is also not working
npm install -g console-group
I edit the previous answer, try with npm cache clear --force (sorry my bad)
thanks @javierjsp @benetj
