create-react-app is not working? - node.js

Question

I am a regular react user and usually use create-react-app but from this morning it is not working.
I have checked the npm, it is installed and fine. I have checked that create-react-app is globally installed on my system. The error is coming with some JSON file.
Versions installed on my system:
node -v
v9.0.0
$ npm -v
5.5.1
I have attached the log file below, I'm attaching log file from where the error comes first:

I saw you're using Windows. Try to clean the cache.
npm cache clean --force
or
Goto %appdata%\npm-cache and check if the directory is clean or not. If not, delete all file from the directory manually.
Now try create-react-app yourAppName
