Mac 代理上的 Azure devops 管道：捆绑安装时找不到 Gemfile

根据报错信息：

Could not locate Gemfile

我们的工作区目录中似乎没有Gemfile。

要解决这个问题，我们需要先运行bundle init，然后运行bundle install。

作为测试，我在您的 CmdLine 任务中添加了bundle init，如下所示，它工作正常：

- script: |
   mkdir ios
   
   cd ios
   
   gem install bundler
   
   bundle init
   
   bundle update --bundler
   
   bundle install
   
  displayName: 'Ruby bundle setup'

结果：
