rails up gradeに伴うgemの依存関係の修正(4.2.8 -> 5.0.0.1)

Q&A

Closed

RubyRailsGemBundler

状況

herokuにデプロイしているアプリのpostgres9.6がEOLに。
postgresのversion upに伴い互換性の問題よりrailsを4.2.8から5にupgradeすることになった。

様々な記事を読み漁り、まずrails version up に伴い発生するgemの互換性問題の解決に取り組むが、うまく行かない。

一気にgemをupdateしようとするのが原因か、bundle update が通りません。

まだ怒られる。

上記のメッセージのにあるパッケージは、全てbundle updateに記載していたはずなのに。

なにかお気づきの点があれば、ご教授お願いいたします。

追記

下記の箇所のjquery-rilas要求するrailties versionに矛盾が起きていることに気づきました。

Gemfile.lockを確認すると下記の記載がありました。
私の理解ではjquery-rails was resolved to 0.1.2　この記述の意味は、
「Gemlock.fileによりjquery-rails のバージョンは0.1.2に指定されている」です。
しかし、上のjquery-railsは0.1.2 下は1.0.19、gemfile.lockは4.4.0で、おかしなことになっています。
私の解釈は間違っているのでしょうか。

また、bundle update実行時、railtiesのdependency は~> 3.0ですが、
Gemfile.lockやrubygems.orgには、railties (>= 4.2.0)
このように記載されています。

terminal
Bundler could not find compatible versions for gem "rails":
  In Gemfile:

    jquery-rails was resolved to 0.1.2, which depends on
      rails (~> 3.0.0.rc)

      railties (= 5.0.0.1)
Gemfile.lock
jquery-rails (4.4.0)
      rails-dom-testing (>= 1, < 3)
      railties (>= 4.2.0)
      thor (>= 0.14, < 2.0)

追記2

試しにgem jquery-railsをコメントアウト。
メッセージが変化。

terminal
Bundler could not find compatible versions for gem "rails":
  In Gemfile:
    rails (= 5.0.0.1)

    quiet_assets was resolved to 1.0.0, which depends on
      rails (~> 3.1)

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    quiet_assets was resolved to 1.0.1, which depends on
      railties (~> 3.1)

    rails (= 5.0.0.1) was resolved to 5.0.0.1, which depends on
      railties (= 5.0.0.1)

調べてみると、gem 'quiet_assets'はrails5に取り込まれたらしい。

なので、gem 'quiet_assets'をコメントアウトし、再びbundle update
エラーメッセージより一部抜粋

terminal
Bundler could not find compatible versions for gem "websocket-driver":
  In snapshot (Gemfile.lock):
    websocket-driver (= 0.7.5)

  In Gemfile:
    rails (= 5.0.0.1) was resolved to 5.0.0.1, which depends on
      actioncable (= 5.0.0.1) was resolved to 5.0.0.1, which depends on
        websocket-driver (~> 0.6.1)

    poltergeist was resolved to 1.18.1, which depends on
      websocket-driver (>= 0.2.0)

websocket-driverのupdateが必要そうなので、bundle updateに書き加える。

terminal
$ bundle update actionpack rails railties ml-rails devise rspec-rails letter_opener_web metamagic coffee-rails dotenv-rails quiet_asse sassc-rails web-console actionmailer rails_script quiet_assets factory_bot_rails websocket-iver

terminal
$ gem install activesupport -v '5.0.0.1'

    wrong number of arguments (given 4, expected 1)

調べると、このエラーはrubygemsのバージョンが原因らしい。
rubygemsのバージョンを確認

terminal
$ gem env version
2.7.6

rubyのversinは2.5.3だから、rubygemsのversionは2.7.6以降でないといけないが、要件は満たしている。

rubyのversionを2.7.4に上げたら、bundle update無事に通った。
新しいバージョンを使うことが超大切だと学んだ。
