Change that to

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

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.

So I install ruby 2.7.7

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.

Hi,
I need a quick ruby primer, please.

I'd like to install this,

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.
