About the Linux installer:
The Linux build is generic enough that it should work on most distributions, including relatively old distributions. Racket may also be available through your distribution's package manager, in which case Option 2 below may work better, as long as the available version is not much older than the latest Racket version.
Running the Linux installer:
After downloading the installer file, run it with
rhombus_racket.sh
to install, possibly adding sudo to the start of the command to install to a location that requires administrator access.
Intel Mac users:
Select the 64-bit Intel option in Platform.
About source distributions:
The Source + built packages distribution is recommended, instead of the selected Source distribution. The Source + built packages distribution includes pre-built, platform-independent bytecode; it installs much faster than plain source, and it is also compatible with fast installs of additional Racket packages.
When upgrading:
To restore packages installed for a previous version of Racket, use DrRacket's File > Package Manager > Copy from Version or at a command line use raco pkg migrate.

Option 2: Rhombus as a Package
Install Racket

Then, install the rhombus-main package in one of these ways:

To get version 0.45 specifically:
Use the package catalog
https://download.rhombus-lang.org/releases/0.45/catalog/
To check or change the set of package catalogs that your Racket installation is using, see DrRacket's File > Package Manager > Settings tab or at a command line use raco pkg config.
To download all package sources and a catalog that refers to them, instead of using the above catalog URLs, see the Rhombus packages only section of the full installers list.
Installation of package executables:
By default, packages are installed in a user-specific location, which means that the rhombus executable is not in the same place as the racket executable.

If you have write access to the Racket installation, put Rhombus there through DrRacket’s dialog by clicking Show Options and then changing Package Scope to installation, or include -i to the raco command line:

raco pkg install -i rhombus-main

Otherwise, run this Racket module to see the path where user-scope executables are installed on your system.
