## Set location for npm packages with repl sessions
https://sabljakovich.medium.com/how-to-use-npm-packages-with-node-js-repl-sessions-cd77300ebfe2
## Dependencies versionn
The iSH-App on iOS has the following latest versions available
- nodejs v16.11.1
- npm v7.17.0
These versions are deprecated, but if we want to use these scripts on iSH, we have to make sure they run on that outdated versions.
- only commander v11 supports nodejs v16
