rake db:create 在尝试为开源项目 kandan 创建数据库时出现错误

rake db:create giving me an error when trying to create db for open source project kandan

我终于在 rails 上为开源项目 kandan 和 ruby 安装了所有必需的 gem,但是每当我尝试 运行 rake db:create 我都会抛出这个错误,我不确定如何解决。如果有人能帮助我,我将不胜感激:)

kandan dan$ rake db:create

编辑 这是我的 gemfile:

source 'https://rubygems.org'

# Uncomment next line when using MySQL database
#gem 'mysql2'

group :development, :test do
  gem 'sqlite3'
  gem 'guard'
  gem 'guard-rspec'
  gem 'guard-spork'
  gem 'database_cleaner'
  gem 'jasmine'
end

根据您的 Gemfile,我可以说您的 Gemfile 中缺少 spork 像这样编辑你的 Gemfile

 group :development, :test do
      gem 'sqlite3'
      gem 'spork', :git => 'git://github.com/sporkrb/spork.git'
      gem 'spork-rails' 
      gem 'guard'
      gem 'guard-rspec'
      gem 'guard-spork'
      gem 'database_cleaner'
      gem 'jasmine'
    end

然后运行bundle install 在终端

中通过运行ning初始化
spork rspec --bootstrap

通过 运行ning

重新生成您的 Guardfile
guard init rspec
gurad init spork
