2.2.2 Get Rust

Checkout https://www.rust-lang.org/downloads.html

curl -sSf https://static.rust-lang.org/rustup.sh | sh

One of Stable, Beta, or Nightly version of Rust is OK.

You can put Rust installation in path or set CARGO_HOME environment variable to the path of cargo binary.

If you are using RStudio, you may need to follow the steps below to get the PATH ready:

  1. On launching RStudio from Finder you will notice that it will not get it’s environment from ~/.bashrc or ~/.zshrc. Instead, it will get it’s environment variables from system-wide settings.
  2. To verify, launch RStudio from Finder and type system("echo $PATH"). Then compare by typing echo $PATH in your terminal.
  3. In order to mitigate this, create a start-up initialization script to load your environment variables as configured in ~/.bashrc or ~/.zshrc : touch ~/.Renviron | R_PATH="PATH=$PATH" | echo $R_PATH > ~/.Renviron
  4. Restart RStudio and verify again by typing system("echo $PATH") at command prompt.

2.2.3 Get rustinr

Run This in R:


2.2.4 Get Xcode Command Line Tools
