You use npm install & pack First on a machine that is online you install
npm install pm2
Then you pack it up
npm pack pm2
That gives you a tar file – you copy that tar file to your offline machine and install, like
npm install pm2-2.2.1.tgz
The above however only create a tarball for the specific module expluding dependencies, and you may still have dependencies that you need to resolve. While you could simply walk through and pack every dependency manually, there is a modules that will automated that for you
npm install -g npm-bundle
Then you can do
npm-bundle pm2
for the individual packages, or if you have a package.json for your project
npm-bundle
to pack everything in one big tarball
