Rails 上的最小问题 Ruby
Minitest Issues Ruby on Rails
我正在阅读 Michael Hartl 撰写的 Ruby 教程 Rails 并继续阅读。然而，我在尝试进行一些测试时遇到了问题。
[fran@fran-desktop twitter-clone]$ bundle exec rake test
/media/Data.II/Dropbox/Web Development/odin-project/3. Ruby on Rails/twitter-clone/db/schema.rb doesn't exist yet. Run `rake db:migrate` to create it, then try again. If you do not intend to use a database, you should instead alter /media/Data.II/Dropbox/Web Development/odin-project/3. Ruby on Rails/twitter-clone/config/application.rb to limit the frameworks that will be loaded.

I 运行 rake db:migrate （即使我还没有创建任何迁移）现在错误如下：

这是我的 gemfile：

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.0'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'

会是什么？谢谢。
您正在使用 guard-minitest gem，请查看 the Install section of its README
的第一行
即：
Please be sure to have Guard installed before you continue.
试试这个，暂时移除守卫：编辑你的 Gemfile 并注释掉守卫行：
# gem 'mini_backtrace'
试试这个，同步测试数据库：
bundle exec rake db:test:prepare
试试这个，验证您是否可以连接到开发数据库：
bundle exec rake db
试试这个，验证您是否可以连接到测试数据库：
RAILS_ENV=test bundle exec rake db
如果所有步骤都成功，那么下面是修复守卫的方法：
group :development, :test do
gem 'guard' # NOTE: this is necessary in newer versions
gem 'guard-minitest'
end
然后运行:
bundle
guard init minitest
