My mistake, misconfigured Inspectrum.

Fantastic app, hope to start using this on my next few projects.

Sorry for the very late response, I usually try to get to issues a little faster. I'm glad you figured it out though, and thanks for the feedback :)

For any other users encountering this issue in future, make sure that inspectrum opens when you type inspectrum into your shell. This error occurs when the application can't launch inspectrum, and typically means it hasn't yet been installed. See the Wiki for installation instructions.
