当我尝试在 AWS Elastic Beanstalk(EB) 环境中部署应用程序时，未安装本机 gem。

我尝试了以下方法：

在 EB /var/app/current 目录中使用 gem update bundler 命令更新捆绑程序，但没有改进。 在本地删除 gemfile.lock 和 bundle install 并部署更新 gemfile.lock。

上面的错误每次都会出现。

我正在使用带有 ruby​​ 2.3 版本的 Rails 4.2.4。

请帮助我。谢谢。

【参考方案1】：

我终于通过缓存 gem 解决了这个问题。

我在本地运行 bundle package，它会在 vendor/cache 目录中创建 gem 缓存。

现在，在 AWS 中部署这些缓存的 gem 时，它会尝试使用缓存的 gem，而不是安装它。我不知道这是否是一个好习惯，但它解决了我的问题。

我从 AWS 博客中获得了这个解决方案：Locally Packaging Gem Dependencies for Ruby Applications in Elastic Beanstalk

编辑#1：在答案中添加@sybind 的评论

bundle package --all 将包括all :git references

如果有更好的解决方案，请告诉我。

【讨论】：

捆绑包 --all 将包括所有 :git 引用

我在打包时收到Some gems seem to be missing from your vendor/cache directory. Could not find nokogiri-1.12.4 in any of the sources。我可以在供应商/缓存中看到nokogiri-1.12.4-x86_64-darwin
