Question

我在运行rails服务器的本地计算机上安装了GraphicsMagick和gem，它运行良好。但是，在开发服务器上，使用Passenger和Apache设置环境。我安装了GraphicsMagick并执行了bundle install。它确实成功安装了gem。

但是，当我访问该网站时，我收到以下错误：

There was an error while trying to load the gem 'graphicsmagick'.
Gem Load Error is: Permission denied @ rb_sysopen - mkmf.log

知道为什么会这样吗？

Answer 1

问题在于运行应用的用户没有足够的permission来运行find_executable，也没有写入权限来创建mkmf.log日志文件。

添加具有足够访问权限的usergroup解决了问题。
