Question

我是rails上的ruby新手。我成功安装了它但是当我输入rails s命令时我得到了

/ home / banished / Desktop / myrails / mynewproject / bin / spring：11：<top (required)>': undefined method path_separator＆＃39;对于Gem：模块（＆＃39; NoMethodError＆＃39;）来自bin / rails：3：load' from bin/rails:3:in＆＃39; 我在安装mysql libary后得到了这个错误。我怀疑他们可能是相关的我试过谷歌搜索，但我没有找到足够的答案来解决这个问题请任何帮助??

Answer 1

当我尝试从http://guides.rubyonrails.org/getting_started.html

运行博客示例时，我得到完全相同的错误

我的bin / rails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，所以我改变了它。

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

之后我设法启动服务器

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

=> Run `rails server -h` for more startup options

可能这样修复是不够的，因为我的bin / rails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信息： - ）

运行错误＆＃34; rails s＆＃34;在ruby中获取（NoMethodError）
