Sounds like you should check $PATH before and after the change to see what it's actually doing. Whatever you want to run, say your version of ruby in /some/dir/ruby, needs to appear earlier in the path than the system version, say /usr/bin/ruby... period. It's not rocket science. However, it's not totally straightforward, either. Some updated  command locations require that the shell be rehashed after changing the path cuz the shell may cache the location - hash -r, or equivalent. That said, it's usually pilot error messing with path. 

echo "PATH: $PATH"
before setting and after to see what's going on. then it's just a matter of figuring out which ruby comes first.

This is the only way I can get it to work right without error


export

It doesn't like :$PATH at the end

I am closer, but my $PATH is still messed up.

This in .bash_profile


export 
PATH=$HOME/bin:/opt/local/bin:/opt/local/sbin:/opt/local/share/man:/usr/X11/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:$PATH


gets me this when I source it


*env: bash: No such file or directory*
dude@mac:~/Extra/sand$ echo $PATH
/Users/dude/bin:/opt/local/bin:/opt/local/sbin:/opt/local/share/man:/usr/X11/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:


notice the trailing ":"
removing it gets me a no such directory error for "/sbin$PATH"

Yeah, this is the answer. You always want `/opt/local/bin/` to be 
near the start of your path. Only stuff that you specifically want 
to override MacPorts should be before it. (Examples of things you 
may want before: RVM or NVM or any of the version managers that put 
things in your home)


Thanks,

    Thank you, I will check that

    I have


    export
    
PATH=$PATH:$HOME/bin:/opt/local/bin:/opt/local/sbin:/opt/local/share/man:/usr/X11/bin


    in my .bash_profile, but echo $PATH shows what you expected:


    dude@mac:~$ echo $PATH
    
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/dude/bin:/opt/local/bin:/opt/local/sbin...


    ok, I have something new to work out.

    No problem. The system ruby showing up instead of
    MacPorts-installed Ruby would be *probably* because your $PATH
    has `/opt/local/bin` *after* `/usr/bin`. Typically, one wants
    to have Macports (or other third-party package systems)
    *before* /usr/local/bin and /usr/bin.

        grrr... it's still trying to use /usr/bin/ruby

        but


        root@mac:~$ /opt/local/bin/ruby -S gem install coltrane


        installed it.

        idky my ruby $PATH seems stuck on /usr/bin/ruby, but
        thanks to your tip, I was able to  install coltrane, and
        it seems to be working. Neato CLI music utility.

        Thank you, Austin!

        I don’t use Macports Ruby (I use `ruby-install`), but try
        this:

        sudo ruby -S gem install coltrane

        Ruby since Ruby 2.x has included Rubygems, and since a
        bit later than that, Bundler.

            sudo gem install coltrane


            won't work because I'm on Mojave with an an ancient
            ruby and this requires ruby 2.7 or above.


            sudo port -vsN install ruby


            installs ruby18 by default


            sudo port -vsN install ruby27
            sudo port select --set ruby ruby27


            installs, but gem still complains.

            just guessing at this point:

            port -vsN install rb-rubygems


            reinstalls ruby18 ><


            Help, please.
