Cette fois, lorsque j'ai essayé d'exécuter minitest, une erreur a soudainement commencé à apparaître, je vais donc décrire l'arrière-plan et la solution.
L'environnement était le suivant.
ruby 2.6.3
Rails 5.1.7
minitest (5.14.1, 5.14.0, 5.11.3, 5.10.3, 5.10.1)
Cet article concerne une erreur survenue lors de la progression du texte ci-dessous.
En ce qui concerne la moindre erreur, l'auteur a également affiché diverses solutions, mais la situation ne s'appliquait à aucune d'entre elles. J'ai soudainement eu une erreur dans le test pendant que le livre était en cours, donc j'ai pensé que c'était probablement dû à un autre travail que j'ai fait entre les deux, donc veuillez vous référer uniquement à ceux qui ont une telle expérience.
Voici les détails de l'erreur.

Il y a un conflit entre 6.0.3.1 et 5.1.7 de support actif.
L'un des facteurs qui me vient à l'esprit est que j'ai travaillé sur diverses choses lors de la création de l'application avec sinatra la veille.
En conséquence, il a été résolu en désinstallant le gem.
ec2-user:~/environment/ruby-book $ gem uninstall activesupport -v 6.0.3.1
You have requested to uninstall the gem:
activesupport-6.0.3.1
activemodel-6.0.3.1 depends on activesupport (= 6.0.3.1)
activerecord-6.0.3.1 depends on activesupport (= 6.0.3.1)
If you remove this gem, these dependencies will not be met.
Continue with Uninstall? [yN] y
Successfully uninstalled activesupport-6.0.3.1
J'ai désinstallé la version 6.0.3.1 ci-dessus.

J'espère que cela sera utile pour ceux qui sont également bloqués.
