我正在尝试将我的项目的Ruby版本从2.3.1升级到2.7.6。但Capstrano部署失败，并显示以下错误：

$ cap app_name deploy

我安装了正确的bundler版本，并删除了默认版本。当前状态：

$ 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的结尾：

BUNDLED WITH
   1.17.2

我不知道在这里该怎么办。我在互联网上发现了类似的问题，但没有一个人有解决方案。
