ruby-on-rails – 旧轨道应用程序的奇怪导轨错误“权限被拒绝：bin / rails”

当我运行rails(或任何rails命令)时,我收到此错误

_rails_command：2：权限被拒绝：bin / rails

只有当我在一些旧的rails应用程序目录.

在这些目录中,包含exec rails c命令,但rails或甚至rails -v不起作用.

背景：
我将编码工作区保留在保管箱文件夹中.
现在我最近安装了Manjaro,因此我从我以前的操作系统下载的所有rails应用程序,我称之为旧的rails应用程序.

简而言之：
除了旧的rails应用程序,Rails的工作正常.
bundle exec rails c工作正常.
我试过的Ruby版本：
2.0.0(rvm),2.1.1(rvm),2.1.1(系统)

宝石环境：

更新：
它在bash中工作正常,这个问题似乎与oh-my-zsh有关.

这是我的rvm-info(从zsh)：

解决方法

在您提到的目录中,您的导轨是可执行模式.如果不可以申请

chmod u+x bin/rails

并使其可执行.
