Having incredible difficulty installing Rstan on MacOS Mojave.— Cannot figure out how to get C++ compiler installed on RStudio.
Tried to follow some of the trouble shooting earlier but have not had success.
Do I need to use R instead?
No. But tell us what the error message is.
So this is what I tried, and this is what happened….
install.packages(“rstan”, repos = “https://cloud.r-project.org/”, dependencies = TRUE)
trying URL ‘https://cloud.r-project.org/bin/macosx/el-capitan/contrib/3.5/rstan_2.18.2.tgz’
Content type ‘application/x-gzip’ length 19107931 bytes (18.2 MB)
Looks fine so far. Was there an error message?
Perhaps try Stan with Mojave MacOS first? Then install.packages("rstan") again. There is more advice for Mojave here: Dealing with Mojave.
Ah the main problem I see is I can’t find devtools
trying URL ‘https://cran.rstudio.com/src/contrib/devtools_2.0.1.tar.gz’
Content type ‘application/x-gzip’ length 388953 bytes (379 KB)
What is the exact code to try there? I tried copying and pasting the command in that reply and just get error messages.
I also have trouble it seems with rlang.
If I remember correctly I had same problem and my issues were solved by installing headers for Xcode
$ sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
