在OSX 10.10 Yosemite上安装Nokogiri

Question

我最近升级到10.10优胜美地测试版,但是我在安装Nokogiri时遇到了麻烦.我正在使用RVM和Ruby 1.9.3.我也按照这里的步骤尝试按照Nokogiri主页上的说明进行操作.

我通过自制程序安装了libxml2(2.9.1)和libxslt(1.1.28),并尝试使用我的Xcode 5安装和Xcode 6 beta中的命令行工具.

gem install nokogiri -v '1.5.5'
Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:

任何人都知道如何解决这些安装错误？

编辑6/10/14:尝试了几天在OSX 10.10上安装Nokogiri之后,我最终放弃了任务并在我的机器上恢复了10.9.需要更新多个库和包才能在10.10环境中工作.

Answer 1

我设法在Yosemite(OS X 10.10预览版)下安装Nokogiri.

第1步:安装Brew

如果安装了brew,请跳过此步骤.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

第2步:安装brew libs

brew tap homebrew/dupes
brew install libxml2 libxslt
brew install libiconv

第3步:下载并安装适用于10.10的Apple Commandline Tools

安装后需要重启是很重要的.

链接:command_line_tools_for_osx_10_10_june_2014.dmg

重新启动后,您可以检查终端中的安装:

> xcode-select --install
-> xcode-select: error: command line tools are already installed, use "Software Update" to install updates

此错误表示您已正确安装命令行工具.

安装Nokogiri

尝试在Gemfile中使用n之前的版本1.6.1,版本1.6.2.1目前存在"10.10预览"的问题.它只适用于我的rbenv Ruby 2.0.0p247,无法在2.1.1上安装.您可以尝试对现有的Ruby版本进行几次尝试.

gem install nokogiri  -v '1.6.1' -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.14/

Answer 2

优胜美地的libxml2 - 1.6.6.2:

sudo env ARCHFLAGS="-arch x86_64" gem install nokogiri -- --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 --with-xslt-lib=/usr/local/lib --with-xslt-include=/usr/local/include

Answer 3

对于Mac OS El Capitan:

gem install nokogiri -v '1.6.7.1' -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2

Answer 4

这对我有用:

ARCHFLAGS="-arch x86_64" gem install nokogiri -v '1.6.0'

Answer 5

我遇到了与MacPorts ruby​​2.1相同的问题:

can not gem install nokogiri on osx10.10 with macports ruby2.1

安装开始,cpu在100%的单核上达到50%,然后CPU下降到接近零,但是iostat tps通过了墙.

这有助于:

# port install libiconv libxslt libxml2

# gem install nokogiri -- --use-system-libraries --with-iconv-dir=/opt/local --with-xml2-dir=/opt/local --with-xslt-dir=/opt/local

Answer 6

这最终对我有用:

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

Answer 7

对于其他任何一个无法在El Capitan上工作的人来说,最终对我有用的是:

sudo gem install nokogiri -- --use-system-libraries --with-xslt-dir=/usr/local/opt/libxslt --with-iconv-dir=/usr/local/opt/libiconv --with-xml2-dir=/usr/local/opt/libxml2 --with-xml2-config=/usr/local/opt/libxml2/bin/xml2-config --with-xml2-include=/usr/local/opt/libxml2/include/libxml2 --with-xslt-config=/usr/local/opt/libxslt/bin/xslt-config

我没有安装macports,我的系统是一个奇怪的大杂烩.强制每个依赖项的特定安装是我可以让Nokogiri编译的唯一方法.超级烦人,但至少它的工作原理.
