(Errno::EACCES)

Question

每当我在所有rails应用程序上输入任何命令时，我都会得到以下错误。我在云中开发虚拟机，有什么想法或指导吗？

Answer 1

听起来您的gems安装了sudo access，您的当前用户(web运行程序？)缺少正确的权限来查看Ruby安装dir。

我不太清楚为什么gems被安装到像/usr/libexec/openshift/cartridges这样的路径上--也许这是云主机设置的一部分？

1. 您从实例中引导您自己的rails服务器吗？比如你自己安装了Unicorn，nginx等？如果是这样的话，您可以使用rbenv将红宝石和宝石集安装到您拥有完全权限控制的本地路径。

如果您没有上面的场景#1，那么安装程序可能会被主机错误配置，您应该打开一张票证。
