Unknown build error, can't install font

[rjacobson16]

I am getting an unknown build error on MacOSX, latest Mojave.

Fonts: original font names are OperatorSsm-Book.otf. I have renamed the files to fit the scheme outlined in the readme: OperatorMono-Book.otf. This results in files in the build folder, but when I double click the file, FontBook opens but does not prompt me to install the font.

Output:

Sorry for the late reply. Based on your comment, are you sure you have the Operator Mono font? Can you post a screenshot from FontBook?

I'm closing this issue. You can reopen if you're still have a problem. Thanks!
