如何避免 bootsnap 和 railties 导致此错误？
How do I avoid bootsnap and railties to cause this error?
----更新
我已经将 repo 克隆到另一个目录并再次抛出所有进程，虽然我注意到这个问题只有在使用后才会出现：
bundle install --deployment --without development test
如果我只使用 bundle install 我可以 rails c 没有问题。
为什么会这样？使用标志很重要吗？我这样做只是因为在 guide on how to deploy Rails app
----更新
我正在尝试在 Ubuntu 上部署一个 ruby 应用程序。我在错误的位置 rails c 正确地获得了 运行 一次相同的回购。
然后我在正确的位置 (var/www/app/code) 执行了所有相同的步骤，但是当我 运行 rails c 我 运行 遇到这个问题时：

我 bundle install 使用了很多 gem install .. 但仍然无法找出问题所在..我也在使用 rvm use 2.6.1 所以我不明白为什么 ruby/2.6.0出现在那里。
无论如何这是我的 gemfile:

你的错误在最后一行；

bundle install --deployment --without development test 命令仅安装生产和一般 gems。不安装开发或测试 gems。 Rails读取环境变量RAILS_ENV设置环境。 RAILS_ENV 变量如果没有设置 rails 默认接受开发。并且捆绑器尝试加载所有 gems + 开发组 gems。但是 bundle install --deployment --without development test 命令只安装生产和一般 gems。所以没有安装 listen gem 因为 listen gem 在开发组。 RAILS_ENV=production bin/rails c 命令未抛出错误，因为未尝试加载开发 gems.

我已经将 repo 克隆到另一个目录并再次抛出所有进程，虽然我注意到这个问题只有在使用后才会出现：

我 bundle install 使用了很多 gem install .. 但仍然无法找出问题所在..我也在使用 rvm use 2.6.1 所以我不明白为什么 ruby/2.6.0出现在那里。
无论如何这是我的 gemfile:
source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }
ruby '2.6.1'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

你的错误在最后一行；
/var/www/swan/code/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.7.3/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:23:in `require': cannot load such file -- listen (LoadError)
bundle install --deployment --without development test 命令仅安装生产和一般 gems。不安装开发或测试 gems。 Rails读取环境变量RAILS_ENV设置环境。 RAILS_ENV 变量如果没有设置 rails 默认接受开发。并且捆绑器尝试加载所有 gems + 开发组 gems。但是 bundle install --deployment --without development test 命令只安装生产和一般 gems。所以没有安装 listen gem 因为 listen gem 在开发组。 RAILS_ENV=production bin/rails c 命令未抛出错误，因为未尝试加载开发 gems.
