我的宝石文件看起来像这样。我曾尝试将unicorn添加到生产块中，但我仍然得到相同的错误。我也删除了独角兽，我仍然得到相同的错误也尝试了捆绑更新无济于事：

source 'https://rubygems.org'

gem 'rails', '3.2.3'

gem 'devise'
gem 'haml-rails'

gem 'omniauth'
gem 'omniauth-twitter'
gem 'omniauth-facebook'
gem 'twitter'
gem 'fb_graph'

gem 'json'
gem 'json_pure'

gem 'simple_form'
gem 'postmark'
gem 'postmark-rails'

gem 'bootstrap-datepicker-rails'
gem 'watu_table_builder', :require => 'table_builder'

gem 'sqlite3'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'uglifier', '>= 1.0.3'
end

gem "therubyracer", :require => 'v8'

gem 'jquery-rails'

gem 'differ'


gem 'whenever'
gem 'unicorn'

任何人都可以帮忙吗？

Answer 1

Unicorn，旨在利用类Unix系统中的功能。

换句话说，它们无法在Windows上运行

Answer 2

问题是Xcode。转到Xcode设置 - ＆gt;下载并确保安装了“命令行工具”。安装完成后，bundle install运行得很好。

Answer 3

我最近遇到过这个问题。在我的情况下，这是因为由于某种未知的原因，CC的环境变量（这是Apple的LLVM编译器的垫片）没有被设置。打字：

$ export CC=cc

在bundle install为我工作之前，终端中的

。

要使更改成为永久更改，您可以将export CC=cc添加到.bash_profile文件中。

如果您执行后者，请确保键入：

$ source ~/.bash_profile

（或打开新的终端窗口），然后再执行bundle install。

Answer 4

这可能需要更新的ruby补丁级别 - 如p194 - 安装它：

rvm install 1.9.3-p194

再试一次。

您应该始终使用可用的最新补丁级别，RVM允许使用：

rvm get stable
rvm use 1.9.3 --install

Answer 5

我使用rvm use system来安装宝石。生活在红宝石边缘的价格？

当我进行捆绑安装时，我收到了kgio gem的gem安装错误
