【问题描述】：
我正在关注 Rails 教程 https://www.railstutorial.org/book/toy_app，但在运行 $ rails generate scaffold User name:string email:string 时遇到错误
这是错误：

我使用的是 Windows 8。我使用的是 Gitbash。我从 install rails 网站安装了 ruby 和 rails。当我输入 ruby -v 我得到ruby 2.1.5p273 (2014-11-13 revision 48405) [i386-mingw32]
我尝试了here 提供的解决方案，但没有奏效。有什么想法吗？
【问题讨论】：
-
你确定你的机器上安装了 sqlite？我不确定 Rails 是否会在您下载时自动安装它。
-
当我输入
sqlite --version时，我得到sh.exe": sqlite: command not found。如何安装？ -
再次检查您是否在 Gemfile 中的
group :development, :test下添加了gem 'gem 'sqlite3', '1.3.9'（并且您运行了bundle install --without production）。 -
是的，我运行了 bundle install --without production。我已经运行了 bundle install 并忘记了 --without 生产，但只是用它再次运行它。
-
刚刚在 irb 中运行了这些命令，不确定是否有帮助：
irb(main):001:0> require 'sqlite3' => true irb(main):002:0> SQLite3::SQLITE_VERSION => "3.8.7.1" irb(main):003:0> exit
