因此,在我寻求使用
ruby dev环境的过程中,我遇到了一个似乎……让这个ruby菜鸟感到困惑的问题.
执行rails服务器时,它会按预期启动,但是当您将localhost:3000放入标准Web浏览器时,它会回复以下内容:
Specified ‘sqlite3’ for database adapter,but the gem is not loaded. Add
gem 'sqlite3'
to your Gemfile.
现在这里是令人困惑的部分.我安装了sqlite3(64位版本,因为这是我下载的,运行的是64位操作系统),由gem查询验证(这里是宝石的完整列表)
卸载和重新安装并不能解决手头的问题,但它确实安装顺利.另外我正在测试的项目的gemfile是folliwing
- source 'https://rubygems.org'
- # Bundle edge Rails instead: gem 'rails',github: 'rails/rails'
- gem 'rails','4.0.0'

正如你所看到的,很早就在Gemfile中指定了sqlite3,但是当我尝试加载主页时,无论出于何种原因,它就像它不存在一样.

以前有人遇到过这个吗?
