错误为宝石安装nokogiri和捆绑安装FOR Middleman应用程序

时间：2015-08-28 20:16:29

标签： ruby-on-rails ruby gem rubygems middleman

我从零开始创建一个Middleman应用程序。每当我尝试运行服务器时，即middleman server我收到一个错误（下面），告诉我“安装nokogiri（1.6.6.2）时出错，而Bundler无法继续。”

但是，当我尝试安装nokogiri（1.6.6.2）时，我收到另一个错误（下面），说“错误：安装nokogiri时出错：错误：无法构建gem原生扩展。”

然后我尝试bundle install我的gemfile但收到另一个错误。谁能告诉我我可能会忽略什么？

每当我尝试运行middleman server命令时，我都会这样：

/Library/Ruby/Site/2.0.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'nokogiri' (>= 1.3.3) among 67 total gem(s) (Gem::LoadError)

    from /usr/bin/middleman:22:in `<main>'

以下是我的Gemfile的内容：

# If you do not have OpenSSL installed, update
# the following line to use "http://" instead
source 'https://rubygems.org'

gem "middleman", "~>3.4.0"

# Live-reloading plugin
gem "middleman-livereload", "~> 3.1.0"

# For faster file watcher updates on Windows:
gem "wdm", "~> 0.1.0", :platforms => [:mswin, :mingw]

# Windows does not come with time zone data

The file "/usr/include/iconv.h" is missing in your build environment,
which means you haven't installed Xcode Command Line Tools properly.

To install Command Line Tools, try running `xcode-select --install` on
terminal and follow the instructions.  If it fails, open Xcode.app,
select from the menu "Xcode" - "Open Developer Tool" - "More Developer
Tools" to open the developer site, download the installer for your OS
version and run it.

2 个答案:

答案 0 :(得分：1)

我在几个系统配置中遇到过这种情况。它总是最终成为开发库依赖项。如果是我，一次一个，我会安装这些并尝试捆绑安装：

libxslt-dev
libxml2-dev
ruby-dev

取决于你的系统（我认为它们是-devel而不是-dev）。

答案 1 :(得分：1)

此命令：

sudo gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2 --use-system-libraries

在this github issue找到的

解决了我的问题。老实说，我不完全确定为什么如果有人可以附加评论，阐明究竟发生了什么，将非常感激。
