ruby-on-rails - 启动rails，sqlite3错误

Question

在检查我的系统是否满足最低要求后，我开始检查版本是否合适:rails new app当新应用程序归零时，我收到消息 NEXT:

         run  bundle install
/var/lib/gems/1.9.1/gems/bundler-1.3.5/lib/bundler/ui.rb:36:in `initialize': undefined method `[]' for #<Thor::Shell::Color:0x95890e0> (NoMethodError)

    from /var/lib/gems/1.9.1/gems/bundler-1.3.5/bin/bundle:20:in `<main>'

进入新创建的 Rails 应用程序。我跑 bundle install于是开始安装并得到以下错误信息:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing sqlite3 (1.3.8), and Bundler
cannot continue.
Make sure that `gem install sqlite3 -v '1.3.8'` succeeds before
bundling.

我已经尝试过，但是当我尝试安装 splite3 时收到一条错误消息:

Answer 1

我有同样的错误，试图开始一个新的 Rails 项目。在这种情况下 sqlite3.h is missing , 意味着缺少 libsqlite3-dev，我猜(我是 Ubuntu 和 Sqlite3 的新手)。答案可以在这里找到:Installing sqlite headers .

~$ sudo apt-get install sqlite3
~$ sudo apt-get install libsqlite3-dev
~$ bundle install

之后， rails server对我来说效果很好。我在本地主机上收到了欢迎。
