Troubleshooting "npm ERR! errno ECONNRESET" Error in Node.js or Next.js

Solutions:

npm config set proxy http://your_proxy:your_port

npm config set https-proxy http://your_proxy:your_port

3. Clear npm Cache:

Clear the npm cache to ensure that any cached data causing the issue is removed:

npm cache clean --force

4. Update npm:

Ensure you are using the latest version of npm:

npm install -g npm@latest

5. Check Firewall and Security Settings:

Verify that your firewall or security software is not blocking npm. Temporarily disable the firewall or adjust its settings to allow npm to access the network.

6. Reinstall npm:

As a last resort, uninstall npm globally and reinstall it:

npm uninstall -g npm

npm install -g npm@latest
