choco install pantheon


The Chocolatey installation installs JDK11 and updates the system JAVA_HOME and PATH environment variables. If your user JAVA_HOME or PATH environment variables are also set, update or remove these.

If you do not want your system settings updated by Chocolatey, install the packaged binaries instead and update the environment variables as required.

Linux / Unix / Windows without Chocolatey



Pantheon requires Java 8+ to compile; earlier versions are not supported. Pantheon is currently supported only on 64-bit versions of Windows, and requires a 64-bit version of JDK/JRE. We recommend that you also remove any 32-bit JDK/JRE installations.
