为什么在Mac OS上安装Nokogiri失败,libiconv丢失?
我一直试图在Mac OS 10.9.3上安装Nokogiri,无论我尝试什么,安装都会失败,并显示以下错误消息:
$ sudo gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.1/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.1/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28 --with-iconv-include=/usr/local/Cellar/libiconv/1.14/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.14/lib

This could take a while...

libiconv is missing. please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

在网络上发现很多帮助后,包括使用brew构建和安装libxml2和libxslt以及从源代码构建libiconv(如“安装Nokogiri”中所述),错误依然存在。
当试图运行Nokogiri的安装时,libxml2和libxslt似乎很好,但不是libiconv。
更了解这些事情的人知道如何安装Nokogiri?
我遇到过同样的问题。 不幸的是,“安装Nokogiri”不包括Iconv问题。 以下是我解决问题的方法。
首先安装自制软件,它会让你的生活更轻松。 如果您已经安装了它,请确保通过如下更新获取最新公式:
brew update
注意 :在OSX 10.9+中,您可能需要安装xCode命令工具才能安装libiconv。
xcode-select --install
然后安装更新版本的libiconv
brew install libiconv
然后链接你的新iconv库:
brew link libiconv
然后安装你的宝石
gem install nokogiri -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.14
尝试使用系统库。 OSX自带更新版本的libiconv,但默认安装脚本似乎有问题
gem install nokogiri -- --use-system-libraries
编辑:如果使用捆绑器,正如Geoff所说,你可以这样做:
bundle config build.nokogiri --use-system-libraries
@ Cory的解决方案包含正确的答案,但小牛的解决方案实际上比顶级解决方案简单得多,所以我只需要进行必要的步骤重新发布。
在小牛队(OSX 10.9+)上:
安装Xcode命令行工具:
xcode-select --install
然后安装你的宝石:
gem install nokogiri
