平台：
Windows 7 64 bit
Rails 4.1.6
gem 2.2.2
按照编译本机gem的安装步骤进行操作。
使用devkit中的实用程序然后configure然后make然后make install。
宝石安装很顺利：
C:\Sites>gem install sqlite3 --platform=ruby -- --with-sqlite3-include=C:\DevKit\home\hivoltage sqlite-autoconf --with-sqlite3-lib=C:\DevKit\home\hivoltage\sqlite-autoconf\.libs
Temporarily enhancing PATH to include DevKit...
Building native extensions with: '--with-sqlite3-include=C:\DevKit\home\hivoltage\sqlite-autoconf --with-sqlite3-lib=C:\DevKit\home\hivoltage\sqlite-autoconf\.libs'
This could take a while...

现在错误是当我尝试运行rake命令时：
C:\Sites\demo>rake db:migrate
rake aborted!
LoadError: 126: The specified module could not be found. - C:/Ruby21/lib/ruby/gems/2.1.0/extensions/x86-mingw32/2.1.0/sqlite3-1.3.9/sqlite3/sqlite3_native.so

(See full trace by running task with --trace)
我还确保gemfile和gemfile.lock列出了正确的版本。
有谁知道为什么我不能让这个sqlite3 gem与我的rails项目一起工作？
