Answer 1

try out below steps to resolve that error

step 1 - remove your node_modules folder

rm -rf node_modules

step 2 -

npm cache clean

step 3 -

sudo apt-get install build-essential

step 4 - remove your package-lock.json and install node modules again.

npm install

(if there is EACCESS error comes then try with sudo command.)

Answer 2

One cause of “code ETARGET” “notarget No matching version found for express@4.17.1” (when running npm update ) is prefer-offline=true in npm configuration, which causes npm (specifically npm-registry-cache ) to never update its HTTP cache if an existing resource was fetched. prefer-offline can be useful to speed up npm ci , but if you use it for npm update , then npm / pacote will cache package metadata requests aka packuments (eg GET https://registry.npmjs.org/express ) forever and will not be able to update to the newest version. So if you have any of prefer-offline=true , cache-min=9999 , offline=true set in the npm CLI flags, environment variables , or npmrc files ( /path/to/my/project/.npmrc , ~/.npmrc , etc.), then don't forget to remove them when performing npm update and npm install .

So the takeaways as far as I can tell are:

• If you use --prefer-offline when you run npm install , npm update , npm outdated etc., then occasionally remove --prefer-offline or npm cache clean .
• Use npm ci --prefer-offline instead of npm install --prefer-offline when doing continuous builds

Answer 3

I solved the issue by

1. Delete node-modules folder
2. Deleting the package-lock.json file
3. Run npm install
4. Now Run npm start
