As has been mentioned earlier, Jovo v4 is still under development, but an early version of the documentation is available at https://v4.jovo.tech/docs/getting-started and an early version of the code may be installable following the instructions there.
I started trying to follow those instructions, and immediately ran into a problem.
npm install -g @jovotech/cli ran. However, when I started to create a new v4 project, I got an error.

So it didn’t install successfully. Any advice from the developers on what to try next?
