Capistrano 部署的 Rails 找不到已安裝的捆綁程序版本

Question

我正在嘗試將項目的 Ruby 版本從 2.3.1 升級到 2.7.6。 但是 Capistrano 部署失敗並出現以下錯誤：

$ cap app_name deploy
  * executing "cd /path/to/app/app_name/releases/20221005131513 && bundle install --gemfile /path/to/app/app_name/releases/20221005131513/Gemfile --path /path/to/app/app_name/shared/bundle --deployment --quiet --without development test"

我安裝了正確版本的捆綁器並刪除了默認版本。 目前state：

$ rvm use 2.7.6
Using /usr/local/rvm/gems/ruby-2.7.6
$ bundler -v
Bundler version 1.17.2
$ which bundle
/usr/local/rvm/gems/ruby-2.7.6/bin/bundle
$ gem list bundler

*** LOCAL GEMS ***

bundler (1.17.2)

Gemfile.lock 結束：

BUNDLED WITH
   1.17.2

我不知道在這里做什么。 我在inte.net上發現了類似的問題，但都沒有解決方案。

最終通過升級 RubyGems 解決：

gem update --system

看起來較新的 RubyGems 版本更新了捆綁器的加載方式。
