如何在AWS OpsWorks中启动Rails控制台

Question

最近，一个应用程序已升级到Rails 6，它在AWS Opsworks上使用Apache和Passenger。

我想知道如何在生产中启动Rails控制台？

deploy@apricots:/srv/www/app_name/current$ bundle exec rails c production

Since bundler is a default gem, you can either remove your dependency on it or try updating to a newer version of bundler that supports bundler as a default gem. (Gem::LoadError)

Note：以前在Rails 5和Nginx Unicorn Server上可以使用。

Answer 1

临时修复

1. 删除Gemfile.lock

2. 使用Ubuntu激活的捆绑器版本生成新的Gemfile.lock。例如：

   $ RAILS_ENV =开发包1.17.2安装

3. 通过以下方式启动Rails控制台：

   RAILS_ENV =开发包1.17.2 exec rails console
