Regardless of which operating system you use, we recommend using rustup to install and maintain your Rust toolchain. On Linux and OS X, you simply run the following command in a shell:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
No further action should be needed.
On Windows, things are a little more involved. First download
rustup‑init.exe from the rustup site and run it, following the on-screen instructions. Rust may require installation of VC++ build tools (more instructions can be found here).
Once installed, execute the following rustup commands:
rustup default stable-x86_64-pc-windows-msvc rustup target add x86_64-pc-windows-gnu rustup target add i686-pc-windows-gnu
Second, install Rtools. The latest installer is available on CRAN. Alternatively, Rtools can be installed using chocolatey:
choco install rtools -y
Finally, make sure that environment variables are set up correctly.
R_HOME should point to the R folder, e.g.
C:\Program Files\R\R-4.1.0 (be careful with spaces in the path).
RTOOLS40_HOME should point to the Rtools folder (usually set up automatically by the installer), which is
C:\rtools40 by default.
PATH should contain paths to
%RTOOLS40_HOME%\usr\bin, as well as cargo, which is found at
%USERPROFILE%\.cargo\bin if installed using
