Out of memory when using jspm install

[delasteve]

In a new folder, I ran jspm init and used all the defaults under Quick setup. It was successful in downloading SystemJS. When trying to install [email protected] I received the following.

$ jspm install angular2
     Updating registry cache...
     Downloading npm:[email protected]

Attempting again, I got:

This is on a fresh $5/mo (512MB RAM, 1 Core) box from DigitalOcean.

Any help would be appreciated. Thanks!

Hey, this happens with npm/other node programs too. Simply not enough memory :( For example, https://www.digitalocean.com/community/questions/npm-gets-killed-no-matter-what

The possible solutions are:

• increase the droplet size (temporarily) to run installations
• don't run install commands on the box and copy jspm_packages/node_modules from your dev machine instead
• try to decrease the default node memory limit which I believe is 1.5 Gb Node.js GC in low memory environments nodejs/node#2738 and http://stackoverflow.com/questions/12779724/limiting-node-jss-memory-usage

Unfortunately jspm does use quite a lot of memory. Reducing this footprint in future will be an ongoing task, and something best worked around in the mean time.
