However, I am still getting the same error. I can confirm that C:/Rpackages is now indeed my default library path, and that it is first (on the left): >.

So I tried changing my default library to the simplest ever location that doesn't have any special characters or require any admin rights, with those instructions. So it seems not related to the package but to something else. This started to happen suddenly a few weeks ago yet never had this issue before. Same thing with alternative remotes command: > remotes::install_github('easystats/performance')Įdit: Note that I am getting the same error no matter what package I've tried to install through devtools (e.g., cardiomoon/processR or r-lib/crayon). I am trying to install package performance development version with devtools but am getting this error: > devtools::install_github('easystats/performance')ĭownloading GitHub repo Failed to install 'performance' from GitHub:Ĭreate process 'C:/PROGRA~1/R/R-40~1.3/bin/圆4/Rcmd.exe' (system error 267, The directory name is invalid.
