我教自己铁路.我是程序员但不是网络程序员.我在这里浏览Michael Hartl的书

它提到从一开始就开始部署应用程序是一个好主意.我同意.所以我在Heroku上获得了一个帐户并经历了设置等.然后创建了我的第一个应用程序,git和工程.然后按照Heroku网站上的所有说明进行操作.最后,我使用此命令将我的应用程序推送到Heroku:

git push heroku master

这本书说在这个阶段可能会出现问题,因为我的机器上的应用程序使用的是sqlite3而Heroku需要postgresql.这本书建议改变我的应用程序的gem文件中的一行

gem 'sqlite3'

至

gem 'sqlite3-ruby', :group => :development

我尝试了然后运行bundle install然后尝试推送应用程序.没有运气我在我的控制台上收到此消息:

An error occured while installing sqlite3 (1.3.6), and Bundler cannot continue.
   Make sure that `gem install sqlite3 -v '1.3.6'` succeeds before bundling.

!!无法通过Bundler安装gem.!!Heroku推送拒绝,无法编译Ruby/rails应用程序

所以我尝试了Heroku网站在这里建议的内容

改变我的宝石文件

由此:

gem 'sqlite3'

对此:

gem 'pg'

所以我尝试了这种方法然后运行'捆绑安装'.但这也不起作用.我在控制台上收到此消息:

Installing pg (0.13.2) with native extensions 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

        /Users/AM/.rvm/rubies/ruby-1.9.2-p290/bin/ruby extconf.rb

我正在启动一个Rails教程,告诉我在创建一个新的演示应用程序时编辑gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.3'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem :development do
gem 'sqlite3', '1.3.5'
end


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.4'
  gem 'coffee-rails', '3.2.2'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platform => :ruby

  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.0'

group :production do
    gem 'pg', '0.12.2'
end

# To use ActiveModel has_secure_password …

我尝试启动我的localhost:3000 RoR应用程序.终端发生的事情:

[omrails]$rails s
Gemfile syntax error:
<<<<<<< HEAD
^

我尝试在Google和Stackoverflow上搜索,但没有发现任何类似于我的问题.我假设ny Gemfile有问题,但我不知道究竟是什么.

我的Gemfile看起来像这样:

source 'https://rubygems.org'

gem 'rails', '3.2.8'
gem 'bootstrap-sass'
gem 'devise'
gem 'omniauth'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'


group :development do
gem 'sqlite3'
end


# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails',   '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby …

我收到此错误

undefined method `default_max_wait_time=' for Capybara:Module (NoMethodError)

当我尝试运行功能规范时，例如

$ rspec规范/功能/auto_policies/3_step_minimal_foundation_spec.rb

...
Performance on MRI may be improved with the concurrent-ruby-ext gem. Please see http://concurrent-ruby.com ...
/Users/mdurrant/eq/lynx/spec/support/capybara.rb:69:in `<top (required)>': undefined method `default_max_wait_time=' for Capybara:Module (NoMethodError)

我已将 Gemfile 更新为最新的水豚 (2.4.4) 但我仍然收到此消息

如何解决这个问题？

在 Rails 控制台中，如何列出环境中已加载的 gem？

我正在使用 Gemfile 和 Rails 5。我四处搜索但没有结果。

尝试推送狂欢沙箱车来测试我要使用的扩展时,我遇到了这个错误.

我的Gemfile

gem 'spree_flexi_variants', :git=>'git@github.com:jsqu99/spree_flexi_variants.git', :branch => 'pre-deface-stable'

heroku的输出推送:

我正在尝试在heroku上部署示例rails应用程序.创建一个非常基本的应用程序,添加一个git存储库,提交所有内容和"heroku创建"后,我将其推送到heroku.终端没有任何错误,但是当我用正确的地址打开浏览器时,我得到以下内容:

The page you were looking for doesn't exist.

You may have mistyped the address or the page may have moved.

我搜索了三个小时并使用了heroku教程如何部署应用程序,但我无法弄清楚我做错了什么.这是我的Gemfile:

source 'https://rubygems.org'

ruby '2.0.0'

gem 'rails', '4.0.0.beta1'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'json'

group :production do
  gem 'pg'
  gem 'rails', '4.0.0.beta1'
  gem 'railties', '4.0.0.beta1'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  #gem 'sass-rails',   '~> 3.2.3'
  gem 'sass-rails',   '~> 4.0.0.beta1' …

每当我跑:

rails -v

我得到了结果

rails 3.2.13

但我的gemfile如下:

gem 'rails', '~> 3.2.12'
gem 'rake' , '~> 10.0.4'

我的gemfile.lock也有3.2.12,但出于某种原因,当我检查verison时,我已经安装了3.2.13.我想这就是我每次尝试运行服务器时都会收到错误的原因:

无法在任何来源中找到rake-10.0.4(Bundler :: GemNotFound)

任何人都可以告诉我为什么我运行rails 3.2.13？我希望运行3.2.12,因为我的技术人员告诉我2.13仍然存在问题,我需要坚持使用2.12.

也有人可以告诉我为什么我得到了rake错误,当我已经安装了rake gem并且它在我的gemfile中.

我是一个红宝石/铁杆新手.

这是我的gemfile:

source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0

gem 'rails', '4.0.0'

group :development do
  gem 'sqlite3', '1.3.8'
  gem 'ruby-debug-ide'
end

gem 'sass-rails', '4.0.0'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.0'
gem 'jquery-rails', '3.0.4'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'
gem 'wash_out', :git => 'git://github.com/inossidabile/wash_out.git'
gem 'haml'
gem "railties", "~> 4.0.0"

group :doc do
  gem 'sdoc', '0.3.20', require: false
end

在捆绑更新,我得到这个:

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    rails (= 4.0.0) ruby depends on
      railties (= 4.0.0) ruby

    sass-rails …

当我尝试开始潇洒时,我收到以下错误:

scheduler caught exception:
uninitialized constant Nokogiri
/Users/Adam/projects/ticker/jobs/sample.rb:2:in `block in <top (required)>'

我的Gemfile是:

source 'https://rubygems.org'

gem 'nokogiri'
gem 'dashing'

我的jobs文件夹包含一个文件夹sample.rb:

SCHEDULER.every '2s' do
  oil_doc = Nokogiri::HTML(open("http://www.bloomberg.com/energy/"))
  a = oil_doc.css("table.std_table_module").first
  price = a.xpath("//td[3]").first.children.text
  send_event('valuation', { current: price })
end

我已经尝试添加 require 'open-uri'到Gemfile和sample.rb但它没有帮助!
