/scripts/dev-bundle-tool-package.js Meteor is using node-inspector 0.7.4. The current version is 0.12.3.
The reason this is a big deal is that node-inspector seems to be horribly broken at the moment. I can’t expand tree elements in Sources or Scope Variables. See the following GitHub issues:
According to #478, this was resolved a while ago, but is still an issue in Meteor. I tried installing node-inspector globally, but
meteor debug is not using it. I’m not sure how to update/change Meteor’s version of node-inspector (I’m on Windows).
