I have put a test R project on GitHub (here), and am trying to install using the following:
devtools::install_github('HamiltonBlake/test')
I get the following output:
Installing github repo test/master from HamiltonBlake
Downloading test.zip from https://github.com/HamiltonBlake/test/archive/master.zip
Installing package from C:\Users\Ham\AppData\Local\Temp\RtmpAzTLDT/test.zip
Error: Does not appear to be an R package (no DESCRIPTION)
If I manually go to https://github.com/HamiltonBlake/test/archive/master.zip and download it, it's a zipped folder with server.R and ui.R as expected.
However when I go to my Temp folder, the zipped folder which has been downloaded above contains an empty file called "file236447a6420", and an empty folder called "rs-graphics-3f4820b1-7366-461a-b095-f2106ef72e73".
I found this question which made it look like it's a matter of waiting a few hours, however unlike this question, I can download and install from the same path that install_github uses, so it looks like github has already updated the master.zip.
I have full read/write access on my PC, and the latest devtools and rtools.
