Answer 1

Based on the error you're getting from Waterline, it looks like a problem with your global Sails' dependencies. That's not the right version of Waterline for Sails 0.9.8. This can happen if you've been trying out other versions of Sails; the npm cache gets a little muddied-up. To correct it, do the following:

1. sudo npm uninstall sails -g
2. npm cache clear
3. sudo npm install sails -g

That will reinstall Sails with all of the correct dependencies. You shouldn't have to change your project.

Answer 2

You may just be missing some modules. For example, if basic dependencies are installed globally with something like sudo npm install sails -g, newly generated Sails app will lift without any problems, but as soon as you start adding some functionality, it may required other modules (probably, DB adapter-related in your case).

Long story short, just run npm install from within your project folder, it will create a node_modules subfolder and install project's dependencies in it.

Answer 3

I saw this problem today. Reinstalling Sails globally didn't work for me because I had two copies of Sails installed. Deleting the locally installed copy forced Node to use the globally installed copy of Sails and all its dependencies which did fix everything.
