Question

这个问题不重复。

我是一名新手，尝试使用https://www.railstutorial.org/book/beginning上的教程学习Ruby on rails。我已经完成了1.3.2之前的各个步骤，但是当我运行＆＃34; rails服务器＆＃34;命令我收到以下错误。根据我读过的一些评论，似乎我需要对sqlite做一个相对要求，因为Ruby已经从加载路径中删除了当前目录。使用require_relative。

我的GemFile如下：

source 'https://rubygems.org'

gem 'rails',                '4.2.2'
gem 'sass-rails',           '5.0.2'
gem 'uglifier',             '2.5.3'
gem 'coffee-rails',         '4.1.0'
gem 'jquery-rails',         '4.0.3'
gem 'turbolinks',           '2.3.0'
gem 'jbuilder',             '2.2.3'
gem 'sdoc',                 '0.4.0', group: :doc

group :development, :test do
  gem 'sqlite3',     '1.3.9'
  gem 'byebug',      '3.4.0'
  gem 'web-console', '2.0.0.beta3'
  gem 'spring',      '1.1.3'
end

＆＃34; Path＆＃34; ＆＃34;系统变量＆＃34;在我的Windows笔记本电脑上（为简洁起见）：

C:\Ruby21\bin;C:\RailsInstaller\Ruby2.1.0\lib\ruby\gems\2.1.0\gems\sqlite3-1.3.9-x86-mingw32\lib\sqlite3\2.0;

C：\ RailsInstaller \ Ruby2.1.0 \ lib \ ruby \ gems \ 2.1.0 \ specifications \ sqlite3-1.3.9-x86-mingw32.gemspec具有以下行：

s.require_paths = ["lib/sqlite3_native"]

我在C：\ RailsInstaller \ Ruby2.1.0 \ lib \ ruby \ gems \ 2.1.0 \ specifications文件夹中有以下sqlite3 gemspec文件。

sqlite3-1.3.9-x86-mingw32.gemspec
sqlite3-1.3.10-x86-mingw32.gemspec
sqlite3-1.3.11-x86-mingw32.gemspec

我应该怎么做呢？
