angular-route error Arguments to path.json must be strings

Question

I am having a hard time figuring out what this error means. I have the following bower.json:

    ...
"dependencies":{
"angular-route":"~1.2.18",
"angular":"~1.2.18"
}

Upon installing my bower packages through bower install I get the following error:

bower angular-route#~1.2.20      error Arguments to path.join must be strings

System info:
Bower version: 1.3.7
Node version: 0.10.26
OS: Linux 3.13.0-29-generic x64

Now, I have to mention that I have done the same thing for about a week, and everything was working correctly, with exactly the same setup. I have noticed that https://github.com/angular/angular.js has released a new version 1.2.20 recently, but even installing that I get the same error.

Some context: I am using nodejs, express and angular in my application. I can provide more info if needed (e.g., package.json, main server file). Any help would be highly appreciated.

See the answer here: Bower - error when installing package "Arguments to path.join must be strings"

Fix: bower cache clean and update to Bower 1.3.8.
