The other day I installed the latest version of
Ruby with asdf. I then set
that version (3.4.1) as the global default. However, when I then ran ruby --version, I was getting a 3.2.x version. I checked my current project's
directory and there was no .tool-versions file, so it wasn't being set by my
current directory.
asdf looks up the current chain of directories until it encounters a
.tool-versions file, so it must have been finding one somewhere up there, but
before it was getting to the global .tool-versions file. But where?
The asdf current command can tell us for a specific tool what the current
version it is set to and what file is giving that directive.
asdf current ruby
ruby 3.2.2 /Users/jbranchaud/code/.tool-versionsAs it turns out, I had a .tool-versions file in $HOME/code that was setting
that 3.2.x Ruby version.
I didn't want that directory controlling the Ruby version, so I removed ruby
from that file. asdf was then able to traverse up to $HOME/.tool-versions
for the global setting.
See asdf help for more details.
