Note: I might be behind a firewall.

1. I installed node.js and
2. then I tried to install weinre via npm. This fails with the following error

Please help me in installing weinre so that i can go on.

Thanks in advance for any help.

There are several things you can do to find out the problem:

1. do an nslookup of registry.npmjs.org to find out if the address can be resolved

2. check your network settings to find out if there is a proxy configured If so, configure npm to use the proxy. This is how you can do this:

   npm config set proxy http://proxy.company.com:8080
npm config set https-proxy http://proxy.company.com:8080
