I have 'meticulously' followed the rdatatable's mac installation wiki. I also tried to follow this blog post to install r via homebrew and then install packages from source.
However, there seems to be a problem that I cannot figure out by myself. Could you please help me out here? I recently downgraded my mac from Big Sur to Catalina. I was able to install packages from source both on Big Sur and previously on Catalina.
install.packages("data.table", type = "source", repos = "https://Rdatatable.gitlab.io/data.table")
