Encounter error when installing react-router-dom

Question

I get this error whenever I NPM install react-router-dom in vs code:

npm ERR! Unexpected end of JSON input while parsing near '...stack-launcher":"^1.0'

npm ERR! A complete log of this run can be found in: npm ERR!

Answer 1

This solved it for me

npm cache clean --force

then run

npm i react-router-dom

Answer 2

Seems like you missed a comma after '...stack-launcher":"^1.0' in the package.json file.

If not delete the node_modules folder, delete package-lock.json file, run npm cache clean --force and try to re-install.
