nvm.sh - executing under ksh fails as local is missing. Remediation by using typeset instead

[chris-day]

Operating system and version:

RHEL9, Ubuntu using ksh as the login shell

Remediation is to change the use of "local" for setting variables and replace with "typeset"

How did you install nvm?

As per the README

What did you expect to happen?

dot-in of $NVM executes without error

Is there anything in any of your profile files that modifies the PATH?

I believe all these errors can be ignored and nvm will continue to work in ksh as-is.

The problem with using typeset is that it doesn’t work on all the other supported shells. If you can suggest a simple way to define a local variable that will work then I’m open to it - this is the reason ksh hasn’t been tested on nvm’s CI for a long time.

[chris-day]

What about testing using "command -v local" and "command -v typeset"? Whichever returns true, you would use as an alias to define a local variable.

[ljharb]

Whatever pattern we use would have to be repeated hundreds of times. What would that one look like?
