Tablesorter

Odd, it's installing fine for me on 9.5.1, enabled via Drush

@wvigen which Core version are you running please? Also, did you pull this module down via Composer or manually?

Did you follow the readme? As the error explains the library is not found and that is not automatically installed. See https://git.drupalcode.org/project/tablesorter#installation

As I had the same error, but following the guide solved the issue for me.

Marking this as "Closed (works as designed)".
