在 ruby 中运行 "rails s" 时出错 获取 (NoMethodError)

Question

我是ruby on rails的新手。我成功地安装了它，但当我键入rails的命令时，我得到了

/home/essedden/Desktop/myrails/mynewproject/bin/spring:11:in <top (required)>': undefined method path_separator'for Gem:Module('NoMethodError'(从料箱/导轨：3：在load' from bin/rails:3:in'中我在安装mysql-libary后得到了这个错误。我怀疑他们可能有关联我尝试过谷歌搜索，但没有找到足够的回复来解决这个问题请帮忙吗？？

当我试图从以下位置运行博客示例时，我得到了完全相同的错误：http://guides.rubyonrails.org/getting_started.html

我的垃圾箱/轨道文件是：

#!/usr/bin/env ruby
begin
  load File.expand_path('../spring', __FILE__)
rescue LoadError => e
  raise unless e.message.include?('spring')
end
APP_PATH = File.expand_path('../../config/application', __FILE__)
require_relative '../config/boot'
require 'rails/commands'

我认为它应该指向同一目录中的spring文件，所以我更改了它。

<   load File.expand_path('./spring', __FILE__)
---
>   load File.expand_path('../spring', __FILE__)

之后，我设法启动了服务器

haahu@haahudev:~/workspace/rails/blog$ bin/rails server

这可能是因为这个修复程序还不够，因为我的bin/rrails文件在APP_path 中仍然有类似的路径引用

APP_PATH = File.expand_path('../../config/application', __FILE__)

但我认为这将是一种新的错误消息：-(
