asdf Seems Broken After Homebrew Upgrade

January 9, 2023 · 1 min read

I upgraded the excellent asdf version manager using Homebrew and ran into a snag when trying to perform mix commands. I encounterd the error /Users/jbrayton/.asdf/shims/mix: line 13: /usr/local/Cellar/asdf/0.10.2/libexec/bin/asdf: No such file or directory. The key to notice here is the path /usr/local/Cellar/asdf/0.10.2/ when the newest version is 0.11.0, as there is clearly a mismatch. I restarted my terminal and shell, but the problem persisted. I noticed all the files in ~/.asdf/shims had the line exec /usr/local/Cellar/asdf/0.10.2/libexec/bin/asdf exec "odbcserver" "$@" # asdf_allow: ' asdf '. This line is not what we wanted and indicates the problem.

After looking at the pinned and then following that to, the solution rm -rf ~/.asdf/shims; asdf reshim fixes my problem. Now, whenever I examine one of the shim files, I see the line exec /usr/local/opt/asdf/libexec/bin/asdf exec "mix" "$@" # asdf_allow: ' asdf ' as expected. The directory /usr/local/opt is what I see when I run the command brew --prefix asdf as the prefix is no longer /usr/local/Cellar/asdf/0.10.2/ or the Cellar location. This corrective measure should be a more permanent solution moving forward as the prefix /usr/local/opt should no longer change in the future.

This issue was also somewhat of a perfect storm as Phoenix 1.7 rc.1 dropped two days ago and I had just upgraded a bunch of homebrew packages, including asdf.
