我用过sudo bundle install,这可能是问题的原因？

我现在有:

• gem -v 2.6.14
• ruby -v ruby 2.3.5p376(2017-09-14修订版59905)[x86_64-darwin15]
• jekyll -v jekyll 3.6.2
• bundle -vBundler版本1.16.0.pre.3

我试图运行bundle exec jekyll serve或只是遇到以下错误jekyll serve

/Users/myusername/.rvm/rubies/ruby-2.3.5/lib/ruby/site_ruby/2.3.0/rubygems.rb:271:in cd my_pathactivate_bin_path'from /Users/myusername/.rvm/gems/ruby-2.3. 5/bin/bundle:23:in sudo bundle installeval'from /Users/myusername/.rvm/gems/ruby-2.3.5/bin/ruby_executable_hooks :15: in`

此外,当访问我有我的博客的文件夹时,gem -v我收到以下消息:

VM使用你的Gemfile来选择Ruby,它很好 - Heroku也这样做,你可以用'rvm rvmrc warning ignore/Library/WebServer/Documents/blog/Gemfile'忽略这些警告.要忽略所有文件的警告,请运行'rvm rvmrc warning ignore allGemfiles'.未知的ruby解释器版本(不知道如何处理):RUBY_VERSION.

我不知道如何解决这个问题.我只是想创建我的静态博客,说实话,我不知道Ruby,Gem或Bundle :)所以我很感激一些见解!

我有一个文件,main.rb,内容如下:

require "tokenizer.rb"

tokenizer.rb文件位于同一目录中,其内容为:

class Tokenizer
    def self.tokenize(string)
        return string.split(" ")
    end
end

如果我尝试运行main.rb,我收到以下错误:

C:\Documents and Settings\my\src\folder>ruby main.rb

C:/Ruby193/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- tokenizer.rb (LoadError)
        from C:/Ruby193/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require '
        from main.rb:1:in `<main>'

我只是注意到,如果我使用load而不是require一切正常.这可能是什么问题？

鉴于以下关联,我需要引用从模型中附加的Questiona .我一直在尝试使用它来执行此操作.ChoiceChoicebelongs_to :question, through: :answer

class User
  has_many :questions
  has_many :choices
end

class Question
  belongs_to :user
  has_many :answers
  has_one :choice, :through => :answer
end

class Answer
  belongs_to :question
end

class Choice
  belongs_to :user
  belongs_to :answer
  belongs_to :question, :through => :answer

  validates_uniqueness_of :answer_id, :scope => [ :question_id, :user_id ]
end

我正进入(状态

NameError未初始化的常量 User::Choice

当我尝试做的时候 current_user.choices

它工作正常,如果我不包括

belongs_to :question, :through => :answer

但我想用它,因为我希望能够做到这一点 validates_uniqueness_of

我可能忽略了一些简单的事情.任何帮助,将不胜感激.

我正在尝试运行，brew doctor但系统弹出错误消息

/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55：在`require'中：无法加载此类文件-active_support / core_ext /对象/空白（LoadError）

在线搜索，另一篇文章建议仅“ gem install activesupport”，但随后我遇到了以下错误：

ERROR:  Error installing activesupport:
    i18n requires Ruby version >= 2.3.0.

我也尝试过rvm安装ruby-2.3.0，但再次弹出相同的错误

当我尝试安装mysql2 gem时,它失败并没有明显的错误.有谁知道如何解决这个问题,所以mysql2安装？

我有一个Ubuntu虚拟机无法连接到具有ssl的站点,即https.如果网址以http开头,它可以成功地从互联网上下载工件.

npm install将通过https下载依赖项.反正是否通过http下载？

我正在尝试在Rails 4.0.8中运行新创建的项目,但我收到并错误:

我一直在阅读很多文章,这些文章解释了在情感分析系统真正起作用之前需要一组初始文本,这些文本被归类为"正面"或"负面".

我的问题是:是否有人试图对"正面"形容词与"否定"形容词进行初步检查,同时考虑到任何简单的否定词以避免将"不快乐"归类为正面？如果是这样,是否有任何文章讨论为什么这种策略不现实？

Rails 3.1 Apache开发环境中的Passenger当我去访问路由的索引(即GET)时,我得到:

Errno::EACCES in Crb_agendas#index

Showing /var/www/crbagenda/app/views/layouts/application.html.erb where line #5 raised:

Permission denied - /var/www/crbagenda/tmp/cache/assets/E2C

Extracted source (around line #5):

当我进入提到的路径(/ var/www/crbagenda/tmp/cache/assets/E2C)时,没有E2C文件夹和root(运行的是什么apache)拥有资产目录...不确定我做错了什么在这....或者我可以展示什么来帮助.

几天来,我一直在抨击我.最近,我的图片上传器已停止正常工作.我已经研究了几种可能性,但没有一个建议的解决方案适用于我的情况.

错误消息是:
