不知道如何构建任务'script / generate'

Question

我今天开始在rails上学习ruby，我总是遇到某种错误。我正在关注tutorialspoint上的教程。现在，当我遇到rails script/generate model Book我遇到了

rails aborted!
Don't know how to build task 'script/generate' (see --tasks)
bin/rails:4:in `require'
bin/rails:4:in `<main>'
(See full trace by running task with --trace)

Answer 1

删除script部分：

rails generate model Book # will work

P.S。每个人都以Hartl's tutorial开头，我认为你也应该这样做。
