PhusionPassenger：无法启动Ruby（Rack）应用程序

Question

我是rails开发人员的新手，我在我的服务器上部署了rails应用程序。但现在它没有启动并在浏览器上给出错误，如下所示：

错误消息：

There was an error while trying to write to Gemfile.lock. It is likely that you need to allow write permissions for the file at path: /var/www/PCMI/zil/Gemfile.lock (Bundler::InstallError)

异常类：

PhusionPassenger::UnknownError

应用程序根目录：

/var/www/PCMI/zil

看起来乘客无法写入您的gem文件的锁定文件。基本上它不能确定你没有捆绑运行，因为它无法获得该文件的独占锁定。

确保用户乘客在（apache默认为www-data）下运行该文件的写入权限。

您可以使用chown和chmod

来完成此操作
