我正在尝试通过 nginx 和 phusion passenger 部署 ROR 应用程序。 nginx 运行得很好，但是我遇到了乘客提出的错误，要求：
应用程序遇到以下错误：您必须使用Bundler 此锁文件为2或更大。 （捆绑器：： LockfileError）
我将捆绑软件更新为版本2.x，删除了GemFile.lock，然后再次安装了项目依赖项，但仍显示相同的错误。错误日志如下。
Error: The application encountered the following error: You must use
Bundler 2 or greater with this lockfile. (Bundler::LockfileError)
