Hi Christopher,
In brief, MacPorts’ “port select” command is working fine at the command-line
in Catalina… but the problem is with installing ANY version of ruby, not
switching between multiple versions of ruby that are already installed.
In a machine where no MacPorts Ruby is installed, the command “sudo port
install ruby27” is not working fully.
The package gets installed, but the links /opt/local/bin/ruby ->
/opt/local/bin/ruby2.7 and /opt/local/bin/gem -> /opt/local/bin/gem2.7 do not
get created automatically. So after installing I always get Apple’s Ruby from
/usr/bin when I use a “ruby” or “gem” command. Of course I can use “sudo port
select” to fix that, and I have done, but it took me several days of
frustration and messing around before I discovered that fact.
I think this is because the port file named “ruby_select”, on which each Ruby
port depends, is broken. You can see this port file’s contents using:
cat $(port file ruby_select)
Compare them to the perl and python “select” files:
cat $(port file perl_select)
cat $(port file python_select)
and I hope you (or someone) will see what the problem is.
Cheers,
Ian Wadham.
