Note :

sails@0.10-rc6 & waterline@0.10-rc11 : throw the error above.

Answer 1

This was an issue introduced into a particular version of Waterline (rc11). It's recommended that you upgrade to the v0.10.0-rc7 release of Sails, which will fix this and some other issues. That's:

npm install sails@beta

or

npm install -g sails@beta

for a global install!
