Solve NPM err! Unexpected end of JSON input while parsing near

I was using node.js Next art-template I found that I reported an error , Namely npm ERR! Unexpected end of JSON input while parsing near This mistake , Because the error has been solved, I won't put the picture .

The solution is as follows ：

npm cache clean --force

The reason why I made this mistake should be that I made it before art-template There was a problem with the Internet , Then I canceled the download , So when I went down again, I reported this error , So use the above command to clear the cache .
