我正在使用中间人3.3.9和 gem ‘sass-rails’, ‘~> 4.0.3’ gem ‘bootstrap-sass’, ‘~> 3.3.1’ gem ‘bootstrap-timepicker-rails’ gem ‘sass’, ‘~> 3.2.19’ 当我运行bundle install时，我收到此错误： Bundler could not find compatible versions for gem “sass”: In Gemfile: middleman (~> 3.3.9) ruby depends on sass (= 3.4.0) ruby sass (3.2.19) 我怎么能通过这个？

切换到捆绑器后如何消除gem错误

我最近切换到使用bundler，现在我随时在rails应用程序的scripts /文件夹下运行脚本时收到以下警告： config.gem: Unpacked gem environment.rb in vendor/gems has no specification file.

Rails失败和奇怪的捆绑安装

有一点我无法弄清楚。 当我尝试运行rails它会说： Could not find sprockets-2.1.2 in any of the sources Run `bundle install` to install missing gems. 顺便说一句，安装了sprockets-2.1.2 。 （我已成功运行bundle install ） 但据我所知，当我运行rails ，全局bin正在运行，因此我无法访问由bundler安装的本地gem。 我可以以某种方式解决这个问题，而无需手动安装很多gem，如： gem install what -v which? 我已经尝试过运行rails了 bundle exec rails … 我没有运气:( 我正在使用RVM（如果这可能是问题的根源

env：ruby_noexec_wrapper：没有这样的文件或目录错误

运行此命令后，我经常收到此错误…. bundle clean –force 在我的rails项目.. 我怎样才能解决这个问题？

如何安装json gem – 无法构建gem原生扩展

我正在尝试将rails应用程序部署到我的ubuntu linux服务器上。 我正在使用capistrano和bundler，当它安装gem时，它失败并出现此错误： Installing json (1.7.7) with native extensions Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /opt/ruby-enterprise-1.8.7-2012.02/bin/ruby extconf.rb creating Makefile make /usr/bin/gcc -I. -I/opt/local/include -I/opt/ruby-enterprise-1.8.7- 2012.02/lib/ruby/1.8/i686-linux -I/opt/ruby-enterprise-1.8.7-2012.02/lib/ruby/1.8/i686-linux -I. -D_FILE_OFFSET_BITS=64 -fPIC -g -O3 -Wall -c parser.c In file included from /usr/include/i386-linux-gnu/bits/posix1_lim.h:157:0, from /usr/include/limits.h:145, from /usr/lib/gcc/i686-linux-gnu/4.6/include-fixed/limits.h:169, from /usr/lib/gcc/i686-linux-gnu/4.6/include-fixed/syslimits.h:7, from /usr/lib/gcc/i686-linux-gnu/4.6/include-fixed/limits.h:34, from /opt/ruby-enterprise-1.8.7-2012.02/lib/ruby/1.8/i686-linux/ruby.h:95, from ../fbuffer/fbuffer.h:6, from parser.rl:1: […]

Rails Gemfile：在开发中使用一行，在生产中使用另一行

我们在生产中使用Heroku运行Unicorn，但在本地机器上使用Webrick进行开发。 我们无法在本地计算机上安装Unicorn。 是否有可能让Rails仅在生产中加载Unicorn gem？ 现在，我们的解决方案是在本地运行应用程序时注释掉Unicorn gem，并在推送到Heroku时取消注释gem。 我们在Rails 3.2.12上。 的Gemfile： source ‘http://rubygems.org’ gem ‘rails’, ‘3.2.12’ gem ‘jquery-rails’ # # ========================================================================================= # # #========================================================================================= gem ‘mongo’ gem ‘mongo_mapper’ gem ‘plucky’ gem ‘bson_ext’ gem ‘bson’ gem ‘newrelic_rpm’ gem ‘rpm_contrib’ # Gems used only for assets and not required # in production environments by default. group :assets do gem […]

awesome_nested_fieldsgem嵌套表单未显示

我一直遇到嵌套表单的问题 – 所以我试图使用以下gem： https ： //github.com/lailsonbm/awesome_nested_fields 。 不幸的是，嵌套的forms（态度）没有出现在任务表单中 – 我试图完全遵循指示 – 我希望它是愚蠢的东西。 加载表单时，我没有收到任何错误。 任务模型 class Task < ActiveRecord::Base has_many :attitudes accepts_nested_attributes_for :attitudes, allow_destroy: true attr_accessible :attitudes_attributes end 态度模型 class Attitude < ActiveRecord::Base belongs_to :task accepts_nested_attributes_for :task attr_accessible :tasks_attributes 结束 任务表格 remove Add Attitudes 当我查看html源代码时，我看到了这一点 <fieldset class=”item”> <label for=”task_attitudes_attributes_new_nested_item_name”>Name</label> <input id=”task_attitudes_attributes_new_nested_item_name” name=”task[attitudes_attributes][new_nested_item][name]” size=”30″ type=”text” /> <a […]

Rails4和Devise（NoMethod错误）

我正在学习如何使用rails gem在ruby上构建Web应用程序。 遵循本教程： http ： //12devs.co.uk/articles/writing-a-web-application-with-ruby-on-rails/ 在我开始为用户身份validationfunction安装Devise gem之前，一切都很好。 在执行rails generate devise:install之后我收到错误 错误报告是这个史诗（看起来我以某种方式搞砸了一些依赖）： sergey@sergey-VirtualBox:~/Bookmarks$ rails generate devise:install /home/sergey/.rvm/gems/ruby-2.1.2/gems/activerecord-4.1.0/lib/active_record/dynamic_matchers.rb:26:in `method_missing’: undefined method `devise’ for Install (call ‘Install.connection’ to establish a connection):Class (NoMethodError) from /home/sergey/Bookmarks/app/models/install.rb:4:in `’ from /home/sergey/Bookmarks/app/models/install.rb:1:in `’ from /home/sergey/.rvm/gems/ruby-2.1.2/gems/activesupport-4.1.0/lib/active_support/dependencies.rb:443:in `load’ from /home/sergey/.rvm/gems/ruby-2.1.2/gems/activesupport-4.1.0/lib/active_support/dependencies.rb:443:in `block in load_file’ from /home/sergey/.rvm/gems/ruby-2.1.2/gems/activesupport-4.1.0/lib/active_support/dependencies.rb:633:in `new_constants_in’ from /home/sergey/.rvm/gems/ruby-2.1.2/gems/activesupport-4.1.0/lib/active_support/dependencies.rb:442:in `load_file’ from /home/sergey/.rvm/gems/ruby-2.1.2/gems/activesupport-4.1.0/lib/active_support/dependencies.rb:342:in `require_or_load’ from /home/sergey/.rvm/gems/ruby-2.1.2/gems/activesupport-4.1.0/lib/active_support/dependencies.rb:480:in […]
