I started facing this issue after upgrading npm package.

You can resolve this with: npm cache clean --force

voila, reinstall the package.

Just in case someone else ends up here and the above answers don't work for them I found after hours of fiddling that downgrading my npm from version 5 to version 4 did the trick:

npm install -g npm@4

After which I closed my CMD and opened it again and was able to install the Angular CLI with the normal command:

npm install -g @angular/cli

Hope this helps someone along the way, cheers!

I am using :

node v12.17.0
npm 6.14.4
Windows 10

I was trying to install Amplify 4.21.0 when I faced:

Error Unexpected end of JSON input while parsing near ....

It worked for me after doing the following steps:

Uninstall and reinstall node.
Delete the files in C:\Users\username\AppData\Roaming\npm-cache
Using the command line as administrator, I run npm cache clean --force
I deleted the package.lock.json file in C:\Users\username.
Then installed Amplify using npm install -g @aws-amplify/cli
