谁能给我解决方案？

Answer 1

在 Rails 5.2 中，您必须安装 bundler 2.0.1 版本。要解决此问题，您可以按照以下步骤操作 -

第 1 步。您已添加 eb 扩展，用于将 bundler 2.0.1 版本安装到 AWS Elastic beanstalk -

# Go to your project root directory
$ mkdir .ebextensions
$ vim .ebextensions/bundler_install.config 

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

步骤 #2。转到 AWS Elastic beanstalk All applications -> example-rails52 -> example-eb-rails52-env 然后单击 Configuration -> Software -> Modify 然后添加此 env 变量

 BUNDLER_VERSION=2.0.1

然后点击保存

第 3 步。再次部署应用

$ eb deploy

希望它应该工作。
