Question

好的，我只是运行我的捆绑安装，当我尝试使用“rails s”运行我的rails服务器时，我收到以下错误消息：

rails s

我也试过运行gem install rails separatley以期解决问题但是没有用。

操作系统：ubuntu 12.04 LTS（32位）

关于我如何解决这个问题的任何指示？

谢谢大家！

Answer 1

很奇怪：运行rails s时出现安装错误？您可以尝试通过执行

在已安装的软件包的上下文中运行该命令

bundle exec rails s

但不确定在这种情况下是否有帮助。

Answer 2

根据我的经验，这发生在异常（缺少系统软件）之后，在先前的捆绑安装期间，没有生成错误。

所以你修复系统软件，安装trouble-gem ok，然后在你之后再次运行'bundle install'时会发生这种情况。您可以整天更改权限，并且会继续创建它无法写入的新文件名。

首先要尝试 - 打开一个新的shell，cd到同一个目录，然后再试一次。这为我解决了。

新的rvm安装和捆绑安装后Rails服务器没有运行
