Docker-compose 和 rails 控制台问题。 'Could not find rake-13.0.6 in any of the sources'

Question

在 docker 下尝试运行 rails 控制台时遇到一些问题。所有其他 rails 命令都按预期工作，但控制台没有。

➜  octopus git:(master) ✗ docker-compose run web bundle exec rails c
Creating octopus_web_run ... done
Could not find rake-13.0.6 in any of the sources
Run `bundle install` to install missing gems.
ERROR: 1

rake 已安装。

➜  octopus git:(master) ✗ docker-compose run web bundle install
Creating octopus_web_run ... done
Using rake 13.0.6
Using concurrent-ruby 1.1.9

而且 docker-compose up 照常工作。

我使用过许多类似的 docker 设置，没有任何问题。我运行没主意了。

非常感谢任何帮助。

Answer 1

每次执行 docker-compose run 都会创建一个新容器，因此之前安装的 gem 不再可用。

为了解决您的问题，您可以运行 bundle install 在 Dockerfile 中，将 gems 安装在 app 文件夹中 bundle install --path vendor/bundle 或者挂载 bundle 默认用于存储 gems 的目录, 通常 /usr/local/bundle

我发现这个问题是在 spring 4.0 (issue 669) 中引入的。束环境变量被忽略。

降级到 spring 3.1.1 修复问题。

Gemfile

gem 'spring', '~> 3.1.1'
