命令“rails server”上的Ruby on rails错误

Question

我遵循github上的所有步骤以及Ruby on rails安装的官方文档。 我已经安装了sqlite3的gem。 另外，我抄的DLL和DEF文件和SQLite到Ruby/bin中的.exe文件 然后我创建了一个示例应用程序称为MYAPP并试图通过命令来启动服务器“轨服务器”

它给以下错误：

F:/Ruby200/lib/ruby/gems/2.0.0/gems/sqlite3-1.3.7-x86-mingw32/lib/sqlite3.rb:6:i

这是 “捆绑列表” 的输出指令：

请HEL p我..我非常渴望在RoR中创建webapps，但我坚持这些错误。 在此先感谢。

下载所需的可执行文件，并从http://www.sqlite.org/download.html解压到你的Ruby的bin中的DLL（F：\ Ruby200 \ BIN）

---

如果您检查sqlite3的源代码：

# support multiple ruby version (fat binaries under windows) 
begin 
    RUBY_VERSION =~ /(\d+\.\d+)/ 
    require "sqlite3/#{$1}/sqlite3_native" 
rescue LoadError 
    require 'sqlite3/sqlite3_native' 
end 

您应用程序中断需要'sqlite3/sqlite3_native'，您可以执行irb并尝试加载该文件，并且它应该失败，修复该问题，并且您的应用程序应该运行时没有任何问题。

确保包含路径的Ruby on％PATH％的二进制文件，所以当你执行需要“sqlite3的/ sqlite3_native”它实际上有该文件的有效路径。

你也可以通过添加您的boot.rb文件尝试：

$LOAD_PATH.unshift('F:/Ruby200/bin') 

因此应用程序，当你需要使用相对路径的文件的sqlite3/sqlite3_native它实际上可以找到该文件。

一旦你能够加载该文件，它应该工作或段故障漏洞（其窗口：P）
