ruby-on-rails - 不知道如何构建任务 'rails'

Question

我正在学习 Ruby on Rails 教程 (Rails 5) Learn Web Development with Rails Michael Hartl，使用 rails 5.0.0.1，当我尝试在 bash 中运行以下命令时

rails generate scaffold User name:string email:string

我收到这个错误

Version: 1.7.2

Usage: spring COMMAND [ARGS]

Commands for spring itself:

  binstub         Generate spring based binstubs. Use --all to generate a binstub for all known commands. Use --remove to revert.
  help            Print available commands.
  server          Explicitly start a Spring server in the foreground
  status          Show current status.
  stop            Stop all spring processes for this project.

Commands for your application:

  rails           Run a rails command. The following sub commands will use spring: console, runner, generate, destroy, test.
  rake            Runs the rake command
rails aborted!
Don't know how to build task 'rails' (see --tasks)
/home/Medo/.rvm/gems/ruby-2.3.1/gems/railties-5.0.0.1/lib/rails/commands/rake_proxy.rb:13:in `block in run_rake_task'
/home/Medo/.rvm/gems/ruby-2.3.1/gems/railties-5.0.0.1/lib/rails/commands/rake_proxy.rb:10:in `run_rake_task'

bin/rails:9:in `require'
bin/rails:9:in `<main>'
(See full trace by running task with --trace)

我不知道是什么导致了这个问题，经过一个小时的搜索也没有找到解决方案。

Answer 1

这对我有用

捆绑安装 --binstubs

之后，rails 就没有问题了
