在这里完成Ruby和Rails的新人...过去曾尝试过一些教程,但那是关于它的.我正在尝试遵循"Ruby on Rails 3 Tutorial"一书,并找到了一个障碍,我在这里和谷歌搜索后找不到任何帮助.

我还没有做过任何事情; 只要:

rails new first_app

然后将Gemfile sqlite3更改为

gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'

当我运行'bundle install'时,我得到以下内容:

Fetching gem metadata from http://rubygems.org/.........
Bundler could not find compatible versions for gem "bundler":

    rails (= 3.0.1) ruby depends on
      bundler (~> 1.0.0) ruby

  Current Bundler version:
    bundler (1.1.3)

This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

我试过通过卸载捆绑包

gem uninstall bundler -v 1.1.3

然后通过安装bundler v1.0.0

gem install …
