Hi Amara,

 

Greetings from Syncfusion support.

We have reviewed your query and understand that you are facing issues while installing the packages. We suggest you ensure the following possible causes and try the given solutions.

 

Possible Causes:

 

1. Incorrect or Unavailable Registry URL in .npmrc
• Your .npmrc file might have an incorrect or outdated registry URL for Syncfusion.
• Run npm config get registry to check if it's set correctly.
2. Blocked by Corporate Firewall or Security Software
• If you’re working within a corporate network, firewalls or security policies may block access to npm.syncfusion.com.
• Try connecting via a mobile hotspot to rule this out.
3. Corrupt npm Cache
• Sometimes, npm cache corruption can cause network-related errors.
• Try running npm cache clean --force and reinstalling.
4. Node.js or npm Version Issue
• An outdated or incompatible Node.js or npm version can cause installation failures.
• Run node -v and npm -v to check, and update if necessary.
5. Incorrect Global npm Configuration
• Check if a global .npmrc file or npm config settings are interfering.
6. Conflicting npm Packages or Lock Files
• Existing package-lock.json or node_modules might be causing conflicts.
• Try deleting node_modules and package-lock.json, then reinstall:

 

Troubleshooting Steps

 

• Clear the npm cache using npm cache clean --force.
• Check your .npmrc file using npm config list.
• Upgrade npm and Node.js (npm install -g npm and ensure Node.js is the latest stable version) as we mentioned in our system requirements documentation manner.
• Disable VPN or any firewall temporarily to see if the issue persists.
• Follow our installation guidelines steps to install packages properly.

Regards,

Prasanth Madhaiyan.
