Unable to install yeoman generators

Question

I am very new to yeoman. I tried running the lessapp yeoman generator, but ran into some weird error. I thought may be it was due to the generator and tried installing another generator bootstrap-less but still it throws the same error. The error comes when I either try to hit the space button or the arrow keys or on hitting the enter button.

I am placing the error stack below.

Please let me know where I am going wrong.

I am using npm version - 2.1.6 and node - v0.10.33 version on mac 10.9.5

Out of the box I include HTML5 Boilerplate, jQuery, and a Gruntfile.js to build your app.

Answer 1

I've got this solved! As benurb suggested here https://github.com/yeoman/yo/issues/247 I manually patched rx.all.js in my C:\Program Files\nodejs\node_modules\yo\node_modules\yeoman-environment\node_modules\inquirer\node_modules\rx\dist

You should replace

shouldRun = predicate.call(thisArg, value, count++, parent);

with

shouldRun = predicate.call(thisArg, value, count++, source);

on the line 4259

Here's the answer I updated just now to this: Issue with selection options on MAC terminal (scaffloding web application using YOMEN)

It is due to the rx.js, yeoman's dependency, released broken version.

The yeomon mod has patched, but it is still not working yet. After they successfully patch to the right version, try this:

npm uninstall -g yo
npm cache clean
npm install -g yo
