问题
I am trying to debug a meteor application at server side.
I created an environment variable export NODE_OPTIONS='--debug'.
I run meteor (version 0.7.0.1) command. It tells the debugger listening on port 5858.
I start node-inspector (version v0.7.0-2) and point to 127.0.0.1:8080/debug?port=5858, but I can see only a couple of strings, Source, Console and a prompt > where I cannot write anything.
I have this error in the console: “The connection to ws//127.0.0.1:8080/socket.io/1/websocket/Za… was interrupted while the page was loading”.
The same if I use 0.0.0.0:8080: I can see something more of the debugger on the right panel, as Watch expression, Call stack, but the Source list is still empty.
Node-inspector should be listening, because if I stop meteor says that the remote debugging has been terminated. I cannot figure out what I am doing wrong.

Just want to share some of my experience on using node-inspector to debug server side codes: 1. When you run Meteor, it will spawn two processes on Linux machine (Note: I have not checked this on Windows or Mac machine)
process1: /usr/lib/meteor/bin/node /usr/lib/meteor/app/meteor/meteor.js
process2: /usr/lib/meteor/bin/node /home/paul/codes/bbtest_code/bbtest02/.meteor/local/build/main.js --keepalive
You need to send kill -s USR1 on process2
Run node-inspector and you can see your server code
On my first try, I modify the last line on meteor startup script in / usr/lib/meteor/bin/meteor to
exec "$DEV_BUNDLE/bin/node" $NODE_DEBUG "$METEOR" "$@"
and run NODE_DEBUG=--debug meteor on command prompt. This only put -- debug flag on process1 so I only see meteor files on node-inspector and could not find my code. Any suggestion on how to modify the script so we can use "--debug" flag on the meteor script? Cheers, Paul
