I am working in a windows environment and have just installed ember-cli@1.13.1 as I am working on an existing project where we cannot upgrade to a newer version. everyone elses environment works fine but on my own workstation the following happens:

If I type C:\> ember I get exactly what I expect, the standard listing of ember help topics. If I then navigate to my Website folder (D:\>development\Jupiter.Europa\Website) and type the same thing (D:\>development\Jupiter.Europa\Website\ember) I get the following:

D:\Development\Jupiter.Europa\Website\>ember Path must be a string. Received null TypeError: Path must be a string. Received null at assertPath (path.js:7:11) at Object.join (path.js:466:7) at AddonDiscovery.

Did you run `npm install` in your website folder? If so, also try deleting `node_modules` and running it again, in case of NPM unreliability.
