Closh requires node version 9, but your version is v12.18.3

[akond]

When I try to install closh via npm install closh I get this error:

ERROR: Closh requires node version 9, but your version is v12.18.3.

Please switch to the required node version and install closh again.

To switch node versions you can use nvm, learn more at https://github.com/creationix/nvm

Once you have nvm you can install the proper node version with:

$ nvm install v9 && nvm use v9

It is like the message says, because of binary modules you need the node version 9. Unfortunately, the project Lumo which is used by closh for nodejs runtime is no longer maintained, so I am not planning to put work into upgrading support for newer node versions.

I suggest you try the Java based version instead. I am working on a way to package closh in a single binary so it will run without Java. After that is complete, I think I will retire the nodejs version completely.
