I installed jshint-mode following the instructions on the front page and using npm. Whenever jshint-mode runs I see the following on the jshint-mode buffer and do not receive any expected errors.

        throw e; // process.nextTick error, or 'error' event on first tick
TypeError: Cannot call method 'indexOf' of undefined
    at getOpt (/usr/local/lib/node_modules/jshint-mode/jshint-mode.js:22:28)

I had the same problem on Mac OSX 10.6, running Emacs 23.3.1 and node v0.6.5. I managed to hack my way around it by editing the jshint-mode.js file. I simply replaced 'ARGV' with 'argv' in lines 22 and 23.
It's probably not the proper way to fix this, but it worked for me…


Feb 2015 , still same error I'm using debian
anyone managed to find a solution instead of manually editing the file ?

I guess this is because of the npm package is not updated, better install it directly through the git repo here which is updated,

flycheck which is supposedly a better version of flymake, now has built in support for jshint directly.
