Updating to 1.4 - need to do on all development computers?

Due to some NPM package requirements, we’re finally upgrading to Meteor 1.4. But updating is seeming to be problematic. Already installed the build tools, but had issues with the commands not working. After a restart, it seemed to update to 1.4, but then errored when updating packages.

So I ran NPM rebuild, which seemed to work fine. But attempting another meteor update, it says current version of meteor is already, but still errors while upgrading packages.

Trying to work this out, but I have another question now - Will each individual computer we develop on need to perform this update? Or will that automatically be handled once they update on github?

I’m concerned that the other users will run in to the same (Or different) issues, and the final installations may not match up…
