在El Capitan上安装Nokogiri(1.6.7)时出错

我的一个开发人员已经更新了Nokogiri,当拉动更新后的Gemfile时,我的bundle install失败。

Make sure that `gem install nokogiri -v '1.6.7'` succeeds before bundling. 

正如“ 未能安装Nokogirigem ”中所述,我试图运行失败:

 bundle config build.nokogiri --use-system-libraries bundle install 

正如“ 没有安装Nokogirigem ”中所提到的,我也尝试过:

 gem install nokogiri -- --use-system-libraries 

和:

 gem install nokogiri -v 1.6.5 -- --use-system-libraries 

我的操作系统版本是El Capitan 10.11.2,我已经检查过Xcode许可协议已被接受。

任何想法如何让Nokogiri安装成功?

你应该先安装xcode-select软件包,然后再尝试安装nokogiri。 试试这些命令,

 xcode-select --install 

然后尝试

 gem install nokogiri 

与任何Nokogiri版本你想要的。

Nokogiri依赖于libxslt,libxml和zlib等多个库。 在任何Linux发行版中安装Nokogiri之前,都应安装这些开发版本(包括源代码)。 对于OS X,上述命令应该工作,我猜。

实际的解决scheme在下面的评论中。

尝试这个 :

 gem install nokogiri -- --use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib/ 

然后运行

 bundle update 

我希望这可以帮助你:)

我正在使用自制软件来维护像libml这样的库,Mac上的以下命令可能会有所帮助:

 gem install nokogiri -v '1.6.8' -- --use-system-libraries --with-xml2-include=/usr/local/Cellar/libxml2/2.9.2/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.2/lib/ 

只要确保libxml的path与我的path相同,除非brew在下一个版本中改变。 你可以通过运行下面的命令来检查:

 brew info libxml2 

gem "nokogiri", ">= 1.6.7.rc3"添加gem "nokogiri", ">= 1.6.7.rc3"

然后运行

 bundle install 

尝试:

 apt-get install ruby-nokogiri bundle install 

更新Xcode和命令行工具为我解决了所有的错误。 之后,我可以安装使用gem install nokogiri的Nokogiri,之后,gem install rails工作正常。

以下步骤为我工作
