Elastic Beanstalk:找不到具有可执行包(Gem :: GemNotFoundException)的gem bundler(> = 0.a)

此错误信息是众所周知的错误信息。(例如,请参阅https://bundler.io/blog/2019/01/04/an-update-on-the-bundler-2-release.html。)尽管我通过具有以下功能的新Elastic Beanstalk应用程序获得它Ruby 2.6.1和bundler 2.0.1。错误是:

  /opt/rubies/ruby-2.6.1/lib/ruby/site_ruby/2.6.0/rubygems.rb:289:in `find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)

我尝试将以下文件:01_install_bundler.config放在.ebextensions文件夹中:

container_commands:
  01_install_bundler:
    command: "gem install bundler —-version 2.0.1"

尽管这永远不会运行,因为如果我看上面的错误,我可以看到它在部署过程的这一点上正在发生:

.../AppDeployStage0/AppDeployPreHook/10_bundle_install.sh] : Activity failed.

(即在bundle installAppDeployPreHook脚本的命令期间)。请参阅https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/custom-platform-hooks.html以获取PlatformHooks的参考。

我非常确定,如果可以确保所使用的捆绑器版本至少为2.0.0,那么不会有问题。尽管我不知道如何轻松指定。目前,我正在服务器上/opt/elasticbeanstalk/hooks/appdeploy/pre/进行编辑和处理脚本。尽管我显然需要一种自动的,可重复的方法。

令人沮丧的是,ruby 2.6.1并未默认选择捆绑程序版本2.0.0。有任何想法吗?

=============================

更新:

如果我编辑文件 /opt/elasticbeanstalk/hooks/appdeploy/pre/10_bundle_install.sh

if [ -f Gemfile ]; then
  echo "running 'bundle install' with Gemfile:"
  cat Gemfile

  +++ gem install bundler +++
  if [ -d $EB_APP_STAGING_DIR/vendor/cache ]; then
    bundle install --local
  else
    bundle install
  fi
else
  echo "no Gemfile found! Skipping bundle install stage!"
fi

并添加gem install bundler(不包括加号),则此问题得以解决,因为它安装了最新的捆绑程序,即2.0.1。对于那些想知道黑客的人,命令是:

eb ssh

sudo -i

cd /opt/elasticbeanstalk/hooks/appdeploy/pre

vim 10_bundle_install.sh

The problem with this solution is that it feels like a bit of a hack because it doesn't use .ebextensions. Is there a more proper way of fixing this?

因此,这是上述问题的程序化解决方案。在下面创建以下文件.ebextensions/gem_install_bundler.config

files:
  # Runs before `./10_bundle_install.sh`:
  "/opt/elasticbeanstalk/hooks/appdeploy/pre/09_gem_install_bundler.sh" :
    mode: "000775"
    owner: root
    group: users
    content: |
      #!/usr/bin/env bash

      EB_APP_STAGING_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k app_staging_dir)
      EB_SCRIPT_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k script_dir)
      # Source the application's ruby, i.e. 2.6. Otherwise it will be 2.3, which will give this error: `bundler requires Ruby version >= 2.3.0` 
      . $EB_SCRIPT_DIR/use-app-ruby.sh

      cd $EB_APP_STAGING_DIR
      echo "Installing compatible bundler"
      gem install bundler -v 2.0.1

然后,当您下一步时eb deploy,捆绑程序将已更新至版本2.0.1,并且不会再出现上述错误。

最后说明:确保在运行之前提交这些更改eb deploy,或者暂存并运行eb deploy --staged。请参阅:https//docs.aws.amazon.com/elasticbeanstalk/latest/dg/eb3-cli-git.html。我经过惨痛的教训才学到这个!
