devtools::install_github("marcusvolz/mathart") fails

Hi Marcus,

I am trying to install your packages as per https://github.com/marcusvolz/mathart/blob/master/README.md.

However, when I run

devtools::install_github("marcusvolz/mathart")

I get below output (note the error "Error: Failed to install 'mathart' from GitHub" and everything below). For some reason, I don't have your folder

marcusvolz-mathart-e792c15

in C:\Users\chris\AppData\Local\Temp\Rtmp8YcPnw\remotes3d6819ce6dd2...

Any idea what's going on here/how I can fix this so that I can use your package? :) Thanks!

Chris

Hi Chris, sorry the package isn't installing. I just did a fresh re-install on my machine and it seems to be working ok for me.

There might be some useful info here, but I'm not sure if there was a clear resolution:
