Having trouble rebuilding main.js - Cannot find module 'browserify-swap'

I’ve installed (perhaps not properly?) npm and Node.js onto my Ubuntu 14.04 machine.
Here is the output in terminal, followed by the log file contents. If someone sees a glaring issue, I’d appreciate it. It seems to be looking for module ‘browserify-swap’ in my source web folder…

Here you see I try “npm run bundleDebug”:

bbiales@ubuntu:~/git/graphhopper/web$ npm run bundleDebug

> graphhopper-js-ui@1.0.0 bundleDebug /home/bbiales/git/graphhopper/web
> browserify src/main/webapp/js/main-template.js --debug -o src/main/webapp/js/main.js

Can you try to upgrade node and npm? Using npm 3.10.7 and node v6.4.0 should be something which works :slight_smile:

Hmmm. I have npm 3.10.8 and node 7.0.0. You recommend downgrading them then? I had installed node 6 (I’m assuming it was the “latest” version of 6) and that didn’t work, so I tried upgrading that.

I also had executed "sudo npm install -g browsifyer"
and the same for browsifier-swap.

Now I tried it without the -g scope, and now I get a different error: Cannot find module 'leaflet’
So I executed: "sudo npm install leaflet"
It gets further now. Says it cannot find module ‘d3’…
“sudo npm install d3”, then try to bundle:
Cannot find module ‘leaflet-loading’
… Did I miss a step? Why do I have to keep running these installs? Was there an automated step to do all these I missed?

Well, I continued installing one at a time as the bundle reported one was missing. I think there were about 3 or 4 more to go. Now I got all the dependencies, and it is working!

Normally a simple (sudo) npm install should be sufficient. Did you try this before as recommended in the docs? Maybe the docs are a bit hidden?

Dang! Well, if hidden, then the instructions were hidden in plain sight!
I skipped over these instructions:
cd graphhopper/web
# download required packages:
npm install
npm test
# overwrites main.js
npm run bundle

And went straight to the command to “npm run bundeDebug” because I want to be able to step through some of it.

My ignorance of how npm works and missing those steps caused some grief! I didn’t realize that “npm install” installs all the necessary dependencies.

Thanks again for the help.
