Cordova 4.3.0 - build command returns error Cannot find module 'Q'

Question

After updating cordova to version 4.3.0 the command:

cordova build

returns the following error:

    module.js:340
    throw err;
          ^

I have already tried to remove and add the platform ios but nothing changes.

I have tried to run:

sudo npm install -g cordova / sudo npm install cordova
sudo npm install -g Q / sudo npm install Q

but nothing changes.

Any help? Thank you very much

Solution 1

There was a bug and I have released a patch to it:

Apache Cordova ios - Git Repository

Solution 2

This is a bug shown on case-sensitive systems such as Unix, Linux and some OS X (if set as case-sensitive).

So far, to fix it, you have to locate those files containing a line like this:

 Q = require('Q')

You can locate the files while standing on your project directory using grep:

grep -HnrI "require('Q" *;

then, use any text editor to manually change the mentioned line to:

Q = require('q')

Alternatively you can edit the related files on a more straight forward way by running the following command on your project directory:

grep -rl "require('Q" * | xargs sed -i "" "s/'Q'/'q'/g";

The single line above searches and edits the files that need the change.
