标签： ruby-on-rails docker rake

我在docker中运行了一个基本的Rails应用程序。我可以很好地启动它并提供响应。我可以运行rake -T就好了。但是我无法运行Rails生成命令。它没有告诉我Could not find rake-12.3.1 in any of the sources 

$ docker-compose run main bundle exec rails generate controller Welcome index
Starting cognitopoc_db_1 ... done
Could not find rake-12.3.1 in any of the sources
Run `bundle install` to install missing gems.

这是我的包env：

$ docker-compose run main bundle env 
Starting cognitopoc_db_1 ... done

这是我的Gemfile：

这是Dockerfile：

那么为什么我能够rake -T打不到rails generate？

5 个答案:

答案 0 :(得分：4)

当我使用Bitbucket管道容器升级以使用Ruby 2.5.1容器时，我开始收到此错误。虽然它可能无法解决每个人的用例，但我可以通过将其添加到我的bitbucket-pipelines.yml来获得我的rails（rake）命令：

bundle install --binstubs

答案 1 :(得分：2)

有趣的是，当在docker-compose中捆绑时，一些人开始在同一版本的Rake中同样出现同样的错误。我不能说是什么导致它发生，但我找到了一个适合我的解决方案。

您可以尝试执行以下命令来删除Gemfile.lock和.bundle目录并重新捆绑。我从这篇博客文章中得到了这个想法：https://makandracards.com/makandra/1667-how-to-fix-gems-are-unavailable-although-they-are-installed 

$ docker-compose exec main bash
$ rm -rf .bundle/
$ rm Gemfile.lock
$ bundle install
$ rails c # => This now works

答案 2 :(得分：0)

可能在docker-compose.yml中定义BUNDLE_APP_CONFIG如下所示可以解决问题。

environment:
  BUNDLE_APP_CONFIG: /myapp/.bundle

关注后，再次运行bundle install。

答案 3 :(得分：0)

我通过禁用spring DISABLE_SPRING=1 bin/rails console解决了这个问题。

答案 4 :(得分：0)

如果您不想禁用spring，请不要使用任何建议的解决方案：

  1. DISABLE_SPRING var，因为它当然会禁用spring
  2. bundle install --binstubs，因为它将覆盖bin / rails和其他可执行文件，以避免春季使用。

我使用的是Rails 5.1.6和Ruby 2.6.6，Bundler 2.1.4，Spring 2.0.0。阅读了一些有关spring gem的PR和Changelog之后，我将spring更新为2.1.1，然后问题解决了。因此，我仍然可以在docker容器中使用spring。
