铁轨找不到耙gem
我有一个在docker中运行的基本Rails应用程序。 我可以很好地启动它并提供响应。 我可以跑rake -T就好了。 但是我无法运行Rails生成命令。 它告诉我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.
这是我的捆绑环境：

这是我的Gemfile：

这是Dockerfile：
FROM ruby:2.5 ARG DEBIAN_FRONTEND=noninteractive RUN apt-get update -qq \ && apt-get install -y \ apt-utils \ build-essential \ nodejs RUN mkdir /myapp WORKDIR /myapp COPY Gemfile* /myapp/ RUN bundle install --path vendor/cache --jobs=4 COPY . /myapp CMD bundle exec rails s -p 3000 -b '0.0.0.0'
这是撰写文件：
version: '3' services: db: image: postgres volumes: - ./pg_data:/var/lib/postgresql/data main: build: . volumes: - .:/myapp ports: - "3000:3000" depends_on: - db
那么为什么我能够运行rake -T bunt而不是rails generate ？
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来获取我的rails（rake）命令：
bundle install --binstubs
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
可能在BUNDLE_APP_CONFIG -compose.yml中定义BUNDLE_APP_CONFIG如下所示可以解决问题。
environment: BUNDLE_APP_CONFIG: /myapp/.bundle
下面后，再次运行bundle install 。
