環境構築でbundleインストールのエラーの件

下記内容で環境構築を試みています。
$ git checkout -b fix_[自分のアカウント名]
$ rbenv local 2.6.6
$ nodenv local 12.14.0
$ bundle install --without production
$ yarn install
$ rails db:migrate
$ rails server

現状発生している問題・エラーメッセージ

higmonta@higuchiyuunoMBP Exam_RailsBasic_01 % rails db:migrate
Could not find mimemagic-0.3.10 in any of the sources
Run bundle install to install missing gems.
どの処理までうまく動いているのか

最初に掲げた環境構築の条件のうち以下は、うまくいっています。
$ git checkout -b fix_[自分のアカウント名]
$ rbenv local 2.6.6
$ nodenv local 12.14.0
$ yarn install

エラーから考えられる原因

rails db:migrateのエラー内容からもmimemagicのmimemagic-0.3.10のインストールができていないのかと考えました。
最初に掲げた環境構築の条件にある以下コマンドを実行した結果が以下になっています。

higmonta@higuchiyuunoMBP Exam_RailsBasic_01 % bundle install --without production
[DEPRECATED] The --without flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use bundle config set --local without 'production', and stop using this flag

Ensure you have either installed the shared-mime-info package for your
distribution, or
obtain a version of freedesktop.org.xml and set FREEDESKTOP_MIME_TYPES_PATH to
the location
of that file.

This gem might be installed as a dependency of some bigger package, such as
rails, activestorage,
axlsx or cucumber. While most of these packages use the functionality of this
gem, some gems have
included this gem by accident. Set USE_FREEDESKTOP_PLACEHOLDER=true if you are
certain that you
do not need this gem, and wish to skip the inclusion of freedesktop.org.xml.

The FREEDESKTOP_PLACEHOLDER option is meant as a transitional feature, and will
be deprecated in
the next release.

試したこと

試したこと1
上記の内容にwithoutフラグは、非推奨になったとあるので、記載通りの下記コマンドを実行しました。

higmonta@higuchiyuunoMBP Exam_RailsBasic_01 % bundle config set --local without 'production'
higmonta@higuchiyuunoMBP Exam_RailsBasic_01 %
上記のように何も返ってきませんでした。

試したこと2

試したこと3
mimemagicにエラーが関係していると考え、ターミナルにてgem listで確認したところ、mimemagicの記載がありませんでした。
補講課題(バグ修正)のgemlockファイルには、mimemagicが記載されているため、それが原因かとも思いました。
一旦mimemagicのみインストールして試してみようと試みたところ以下のようになってしまいました。

higmonta@higuchiyuunoMBP Exam_RailsBasic_01 % gem install mimemagic -v '0.3.10' --source
ERROR: While executing gem ... (OptionParser::MissingArgument)
missing argument: --source
今度は引数がおかしいと上記のようなエラーが出てしまいました。

下記のエラーよりmimemagicにエラーがあると自分で考察して試行錯誤している状況です。

higmonta@higuchiyuunoMBP Exam_RailsBasic_01 % rails db:migrate
Could not find mimemagic-0.3.10 in any of the sources
Run bundle install to install missing gems.
bundle installで実行してもダメでした。
