錯誤（NoMethodError）

Question

我是新來的Ruby on rails.I安裝成功，但是當我鍵入軌的指揮，我得到

/家庭/放逐/桌面/ myrails/mynewproject/bin/spring：11：in <top (required)>': undefined method path_separator'for Gem：Module（'NoMethodError'） from bin/rails：3：in load' from bin/rails:3:in' 安裝mysql libary後我得到這個錯誤。我懷疑它們可能是相關的 我試過谷歌搜索，但我還沒有找到足夠的迴應解決這個問題 請任何幫助？

Answer 1

我得到了完全相同的錯誤，當我試圖運行博客例如，從：http://guides.rubyonrails.org/getting_started.html

我斌/軌文件是：

#!/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' 

我認爲它應該指向春天文件，它是在相同的目錄，所以我改變了。

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

後，我設法啓動服務器

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

這可能是這樣，這個解決辦法是不夠的，因爲我的斌/導軌文件仍在APP_PATH

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

具有相似的軌跡基準

但我認爲這將是一種新的錯誤信息:-)
