Error when installing brms package in R - bayesplot cannot be installed - r

Question

I am trying to install the R package brms on my Ubuntu 22.04 LTS computer. My R version is 4.2.2 and I am using RStudio RStudio 2022.07.2 "Spotted Wakerobin".
rstan is installed and I have successfully verified the installation. My stan version is 2.21.0.
When I try installing brms in RStudio this is the output:
> install.packages("brms")

There seems to be a problem when installing bayesplot but I'm not sure how to solve it.
Does anyone have any suggestions?

Answer 1

Just in case someon encounters the same problem:
I installed devtools to be able to install bayesplot directly from github using:
install_github("stan-dev/bayesplot", dependencies = TRUE, build_vignettes = FALSE)
This only worked for me after installing all the packages that throw compilation errors in R directly and not in RStudio.
After bayesplot was installed, I was able to install brms.
