The shims go on your PATH , so your shell, editor, and scripts use racket directly. Switch the active toolchain with rackup default . The first toolchain you install becomes the default automatically. $ rackup install stable $ rackup install pre-release $ rackup default stable $ racket -e '(displayln (version))' $ raco pkg install gregor Commands rackup install name Install a toolchain rackup list List installed toolchains rackup available List installable toolchains rackup default name Set the global default toolchain rackup current Show the active toolchain and its source rackup switch name Switch the active toolchain in this shell rackup run name -- cmd Run a command using a specific toolchain rackup which cmd Show path for a shimmed command rackup link name path Link a local source tree rackup remove name Remove an installed toolchain rackup prompt Print toolchain info for shell prompt rackup reshim Rebuild shims from installed toolchains rackup doctor Print diagnostics rackup init --shell sh Set up shell integration rackup self-upgrade Upgrade rackup itself rackup uninstall Remove rackup and all managed state rackup version Print version info
