I am making my way through the Rails for Beginners course and after a bit of a hiatus I started back in it. However, now when I run ruby s I get the following error: ruby: No such file or directory -- s (LoadError) If I run ruby -v I get ruby 3.0.3p157 (2021-11-24 revision 3fb7d2cadc) [x86_64-darwin21] What should I do to get ruby s back up and running?
- Make sure run
rails sin your Rails project root directory - Try using
./bin/rails sit may works

Thank you @Zheng_Cheng I am in the root directory so I tried #2, which returned this error:

Could it be that there something wrong with my postgres setup? If so what can I do to fix it?
FYI - I recently installed the Postgresl app and then this problem cropped up so I uninstalled the app following their docs…
Seeing as you’re on MacOS, it’s likely that you could have installed Postgres via HomeBrew. A compatible version of libpq that it’s looking for might be installed, but just could not be located because it’s not properly linked. You could try:
brew link libpq --force
and if that doesn’t work then this might bring things into alignment:
brew update && brew upgrade

Thank you @Lorin_Thwaits I ran brew link libpq --force and it returned:
Linking /usr/local/Cellar/libpq/14.4...
Error: Could not symlink bin/clusterdb
Target /usr/local/bin/clusterdb
is a symlink belonging to postgresql. You can unlink it:
brew unlink postgresql
To force the link and overwrite all conflicting files:
brew link --overwrite libpq
To list all files that would be deleted:
brew link --overwrite --dry-run libpq
So, I tried brew link --overwrite libpq and it returned:
Warning: libpq is keg-only and must be linked with `--force`.
If you need to have this software first in your PATH instead consider running:
echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.zshrc
Looks like a catch-22 to me… So, I moved on to brew update && brew upgrade and it returned Already up to date
Next I tried echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.zshrc but then ruby s is still returning ruby: No such file or directory -- s (LoadError)
I moved on to brew unlink postgresql then brew link libpq --force and I got
Linking /usr/local/Cellar/libpq/14.4... 377 symlinks created.
If you need to have this software first in your PATH instead consider running:
echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.zshrc
But when I run ruby s I still get the same error…
