@Musicminion 你已经参加工作了吗？

@Musicminion 这个在部署文档里有说明，只不过被大家忽略了。重新看一下文档里的这个初始化数据库的地方有说明如何处理。

你好哇！感谢回复呜呜！看到这个名字瞬间就一股熟悉感了（是交大的老师嘛😂我记得在canvaslms的社区见到过！）

目前在读大三，当初部署的时候还是大二下学期（canvas应该是我部署的第一个app），当时很多东西还不太熟悉，其实现在看起来之前问的问题啊还有写的教程文档有点naive了😂 前些天刚试了一遍，虽然安装过程有一些bug也能解决了！（准备抽空更新一下中文版的部署文档）

它里面的组件版本会经常更新，ruby , bundler, nodejs之类的。官方文档有时候也是滞后的，得多尝试才行。
