Travis-CI cannot find relative module require

Question

I have a Travis build job that is running mocha tests, however the build is failing with the error:

Error: Cannot find module './sources/reddit'

My file tree is the following

feeds/ 
     sources/ 
          Reddit.js
     Feeds.js
app.js

Within Feeds.js I am doing

var https   = require('https'),
    q       = require('q'),
    Reddit  = require('./sources/reddit');

However it seems to be flagging up an error loading it up.

Answer 1

This error is because I was referencing ./sources/reddit with reddit as lowercase, on the filesystem the file is Reddit with an uppercase R.

Mac OSX deals with case sensitivity well, Linux does not.

Answer 2

I also just ran into this issue, but the capitalization issue was harder to detect.

When I first checked the file into git, it was named container.js (lower-case "c"). I subsequently changed it to Container.js, so it reflected the upper-case name on my file-system.

Git, however, doesn't detect the case change on case-insensitive OSs so every time travis-ci runs, it ran against the lower-case name and so failed the build. (See Changing capitalization of filenames in Git for details on how to do this properly)

I solved this by simply renaming the file and changing all references so that git picked up the new name.
