npm install giving Error after so many WARN
If you see the log, for old packages, it gives a Warning and not an Error. The error is actually this line: npm ERR! Unexpected end of JSON input while parsing near '...on" : "10.16.3"
npm ERR!}'
Since you have not included the entire log, with this, I can guess it is possibly an ambiguity issue due to references not properly resolved!
Open command prompt/powershell/terminal, etc. with admin privilege. Do as below: -
sudo npm cache clean --force
sudo npm cache verify
- Delete the
package-lock.json
file located inC:\Users\<your_username>
Try installing your project dependencies now from your project folder with npm i
.
Note: - If this doesn't work, follow the same process as above (again) and uninstall the npm
and node
and reinstall it. It should work then!
