Configure Command Line for Racket by setting your PATH environment variable so you can use racket, raco and other Racket command line functions.

You can set PATH a number of ways depending on your platform.

On macOS:

• Open DrRacket, click on Help then Configure Command Line for Racket…: This will configure your $path environment variable properly.

• Configure /etc/paths.d/racket from the command line:

  • If you have a single installation of Racket (the default), just type: sudo sh -c 'echo "/Applications/Racket v8.0/bin" > /etc/paths.d/racket'

  • If you have multiple installations of Racket (unusual), type instead: sudo sh -c 'echo "/Applications/Racket v8.0/bin" >> /etc/paths.d/racket' but you may wish to edit the file /etc/paths.d/racket to remove obsolete paths.

Note: If there is a signing problem, sudo xattr -r -d com.apple.quarantine /Applications/Racket v8.0/ might help fixing the problem.

Note: If you have installed Racket via homebrew, you shouldn't have anything to do. Homebrew should already configure Racket for you.

On Windows 10:

• Open DrRacket, click on Help then Configure Command Line for Racket…: This will configure your PATH environment variable properly.

• Racket 8.0 or earlier: Add the location of the racket folder to your %Path% environment variable. The location is probably C:\Program Files\Racket\. If you don't know how to do that, follow these steps.

On Linux:

• Ubuntu/Debian: If you chose a Unix-style distribution, or you have installed Racket via apt or the Software Center, you shouldn't have anything to do.

• Otherwise, on Ubuntu, follow these instructions.

• For other Linux users, you probably know what to do.
