Hello! I am a new user to RStan and I ran into an issue when configuring the C++ toolchain and subsequent loading of the RStan package.
I am using Windows 10, R x64 v.4.0.2 and RStudio v.1.3.1073. I followed these instructions to the letter in R and RStudio: https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started. Below are the commands I used an abbreviated version of the output highlighting the error.
> install.packages("rstan", repos = "https://cloud.r-project.org/", dependencies = TRUE) ERROR: compilation failed for package 'jsonlite' * removing 'C:/Users/Allison/Documents/R/win-library/4.0/jsonlite' Warning in install.packages : installation of package ‘jsonlite’ had non-zero exit status The downloaded source packages are in ‘C:\Users\Allison\AppData\Local\Temp\RtmpAnUOQm\downloaded_packages’ > pkgbuild::has_build_tools(debug = TRUE) >library("rstan") Loading required package: StanHeaders Loading required package: ggplot2 Error: package or namespace load failed for ‘rstan’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ‘jsonlite’
Any insights on would be helpful.
