我用

  • Rail 4.2.5.1 在容器中运行
  • Ruby 2.3.1 运行机智容器

当我开始

 $ docker-compose exec web /bin/bash # ssh into the web server
 $ bundle exec rails c

我收到以下错误。

from /usr/local/lib/ruby/gems/2.3.0/gems/bundler-1.13.1/lib/bundler/runtime.rb:86:in `each'
    from /usr/local/lib/ruby/gems/2.3.0/gems/bundler-1.13.1/lib/bundler/runtime.rb:86:in `block in require'

    from /usr/local/lib/ruby/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'

但是我已经把pqgem 放到了 Gemfile 中。我已经尝试过，

$ bundle update pg
$ bundle uninstall pg && bundle install
$ bundle exec spring binstub --all

但是我没有运气。

当我尝试时，

$ docker-compose exec web /bin/bash # ssh into the web server
$ DISABLE_SPRING=1 bundle exec rails c

它确实有效。所以我认为 spring gem 不能正常工作。此外，如果我在本地做同样的事情，它确实有效。

我认为我docker_compose.yml的设置不正确。有任何想法吗？

      - 'redis'
    build: .
    command: rails server -b 0.0.0.0

通过以下方式调用容器内的应用程序bin/spring：

$ docker-compose exec web bash
$ bin/spring rails c

运行测试等也是如此：

$ bin/spring rspec

单独运行 spring 以获得一些额外的提示：

$ bin/spring

我用 Ruby 2.4.3、Rails 5.1.4 和 Spring 2.0.2 对此进行了测试。
