For me  I was trying to install an old version of bcrypt which was not found in npm  I just edited package json and manually put the latest version and then ran npm install and it worked

Novice mistake  Make sure your package json file is coded correctly  I had    start    index node js  instead of   start    node index js    17  Delete your package-lock json file and node modules folder  Then do npm cache clean  npm cache clean --force do  npm install

Finally  I found a solution to this problem without reinstalling npm and I m posting it because in future it will help someone  Most of the time this error occurs javascript heap went out of the memory  As the error says itself this is not a problem with npm  Only we have to do is   instead of   npm  run build -prod   extend the javascript memory by following   node --max old space size 4096 node modules  angular cli bin ng build --prod

Deleting the package-lock json did it for me  I d suggest you not push package-lock json to your repo as I wasted hours trying to npm install with the package-lock json in the folder which gave me helluva errors
