I am getting this strange error trying to run grunt: TypeError: Object Gruntfile.js has no method 'flatten'
I am new to node.js, npm, grunt, etc. I thought I did a decent install of node, npm, grunt but may be I missed something. Is there a way to verify the install??
$ cat xx
$ grunt
/home/cl/node_modules/grunt/node_modules/findup-sync/lib/findup-sync.js:33
}).flatten().uniq().value();
^

Found that this worked, as per https://github.com/gruntjs/grunt/issues/888
rm -rf node_modules/grunt
npm install grunt
This should work too.

Try reinstalling your node modules.
npm cache clean
npm install
Hope it helps :)
