我正在尝试配置Expo：Exchange Portal软件：https://www.cs.bris.ac.uk/~cszjpc/expo.html
在Ubuntu 16.04上
我已经能够在安装ExpoonUbuntu.txt指令中取得很大进展，但是当我调用时，我会抛出以下错误
RAILS_ENV='production' rake db:schema:load
输出：

我对Rails一无所知，并试图让这个应用程序启动并运行一个本科研究项目。不幸的是，研究项目不是关于学习Rails及其历史，但如果我打算使用这个软件，也许我应该学习它。
任何提示或建议？
是否有其他系统信息有用？
提前致谢！
