たんに、直接railsコマンドを使うのを諦めて、bin/railsあるいはbundle exec railsで起動する、では不満でしょうか？

コメントありがとうございます。
bin/railsとbundle exec railsどちらも実行できませんでした。

bundle exec rails sの結果
```
Your RubyGems version (3.0.3.1) has a bug that prevents `required_ruby_version` from working for Bundler. Any scripts that use `gem install bundler` will break as soon as Bundler drops support for your Ruby version. Please upgrade RubyGems to avoid future breakage and silence this warning by running `gem update --system 3.2.3`
Your Ruby version is 2.6.10, but your Gemfile specified 3.2.2
```

bin/rails sの結果
```
Could not find gem 'nokogiri (~> 1.10.2)' in locally installed gems.

The source contains the following gems matching 'nokogiri':
* nokogiri-1.15.4-x86_64-darwin
Run `bundle install --gemfile /Users/oharamasaki/workspace/Travel-Plan/Gemfile` to install missing gems.
