build gruntjs npm dependencies grunt-contrib-uglify

Suddenly grunt build fails

I was used to grunt build task to complete successfully, but since I merged my project edits with some of another developer colleague, it suddenly fails with an error I've never seen before:

grunt build
Loading "imagemin.js" tasks...ERROR
>> Error: Cannot find module 'process-nextick-args'
Loading "cdnify.js" tasks...ERROR
>> Error: Cannot find module 'abbrev'
Loading "grunt-karma.js" tasks...ERROR
>> Error: Cannot find module 'uglify-js'

Running "clean:dist" (clean) task
>> 0 paths cleaned.

Running "wiredep:app" (wiredep) task
Warning: Cannot find module './lang/clone' Use --force to continue.

Aborted due to warnings.


Execution Time (2015-09-25 09:44:30 UTC)
wiredep:app  31ms
Total 31ms

In the Gruntfile.js I commented imagemin and cdnify out in concurrent:dist and build tasks.

What have I done wrong?

Here there are some informations about the version of the stuff I'm using:

node -v && npm -v && grunt --version
v0.10.35
2.1.1
grunt-cli v0.1.13
grunt v0.4.5

Moreover, I tried to run an npm install before the grunt build, but I have these warnings I've never seen before, except the very three ones:

EDIT

Keep in mind that my colleague's package.json doesn't show any difference from mine.

Solution

Looks like you have outdated/mixed npm modules - did you merge your node_modules folder with your colleagues?

Anyway, I suggest deleting your local node_modules directory then re-running npm install.

Once you're stable again, the proper workflow should be:

node_modules should be out of source control
when you first get the project, run npm install to setup your local node_modules
then you only need to touch it when package.json changes
in that case, you run npm update to install the new versions locally
