The CLI tool is built using NodeJS. You’ll have to have it installed first.
The Dolittle tooling platform and this the CLI needs node version >= 10.0.0
Then simply open a shell on any platform and run the following:
$ npm i -g @dolittle/cli
Note that it is actually required to have @dolittle/cli installed globally using -g to make use of the underlying dolittle tooling system.
