Oops. Don't know what fail messages mean:

The command "(mkdir /tmp/urchin && cd /tmp/urchin && curl -s "$(curl -s https://registry.npmjs.com/urchin | grep -Eo '"tarball":\s_"[^"]+"' | tail -n 1 | awk -F" '{ print $4 }')" -O && tar -x -f urchin_)" failed and exited with 56 during .

Does test/slow/nvm reinstall-packages/test-npmlink/index.js need +x file permissions? (the web UI doesn't tell me if it has it or not)

As for that specific failure, it might have been a fluke - I restarted it, and hopefully it will pass this time, or at least have a more helpful error message.

All passed!
So it means I already added +x :)

@hax this is awesome. Thanks for doing this!

I believe the only remaining holes for reinstall-packages-from are:

• packages originally installed from git
• packages that weren't installed at all
• possibly packages that are installed from private registries.
