RVM/Cap/Bundler - 软件包安装无法找到打包程序

Question

我正在运行带有RVM的Capistrano，我试图将我们的部分Web应用程序迁移到新的服务器。我已经完成了帽部署：安装和帽部署：检查，一切似乎都很好。当我运行我的部署，虽然即时得到这个错误

我对rvm不是很有经验，我试过手动安装gem，但我不知道如何进入该目录。我真的可以使用帮助，我觉得我错过了一件非常简单的事情，只是找不到适合我的在线任何地方的解决方案。

Answer 1

安装红宝石后，RVM不会自动安装bundler宝石。 因此，每当您通过RVM安装新版本的Ruby时，都必须在运行后执行gem install bundler命令。

另一个解决方案是编辑~/.rvmrc或/etc/rvmrc您rvmrc CONFIGS并添加rvm_autoinstall_bundler_flag=1

这条线将迫使RVM安装捆绑宝石和运行包安装，如果Gemfile中可用。

希望它有帮助:)
