Error on sails lift since update to 0.10.4

I'm working on a project that was originally made with sails 0.9.8.something and was recently updated to 0.10.4. I've received errors while trying to run sails lift since then. Here's the error:

module.js:340
    throw err;
          ^
Error: Cannot find module './Sails'
    at Function.Module._resolveFilename (module.js:338:15)

    at Module.require (module.js:364:17)

To confirm, I've updated locally:

$ sails -v
0.10.4

And after reading this, I deleted and updated as recommended. Still no luck. Any clue what's up?
