RefineryCMS 图像缩略图未显示

Question

我有一个 RefineryCMS 3 应用程序，但在后端没有显示上传图像的缩略图。

如果我在开发机器上以生产模式运行应用程序，则会显示缩略图。在生产机器上，rails 应用程序通过乘客和 apache 运行，但它失败了。

我已将我的开发副本复制到生产服务器进行测试，并在开发模式下运行了炼油厂项目，但我仍然遇到同样的问题

rails s -b 192.168.200.215

这是我尝试在炼油厂管理中加载图像区域时的标准输出；

当它尝试获取 /system/images/.... 时，它在 Web 浏览器控制台中失败。如果我尝试使用以下内容直接访问它

http://192.168.200.215:3000/system/images/W1siZiIsIjIwMTYvMDMvMDEvN3lmN3ZpNDRtZV9hYWEuanBnIl0sWyJwIiwidGh1bWIiLCIxMzV4MTM1I2MiXV0/aaa.jpg

我在浏览器中收到以下错误

Internal Server Error

Answer 1

生产服务器没有安装 imagemagick。

sudo apt-get install imagemagick

这解决了它。
