Install Errors from 1.4.6 to 1.4.8

Howdy. Excited to see this succeed.

I have 1.4.6 installed on one machine, and 1.4.8 on another. Can't get the test samples to fire on 1.4.8 version.

Looks like there may be a dependency conflict of some kind. Running in to these errors on attempted install from root of project. From the log file after install attempt:

```

```

Then afterward attempting to install from `/samples/mocha` per your instructions before running tests:

```
