在小牛升级后安装nokogiri - entities.c失踪了吗？

Question

我遇到了大多数人在后Mavericks升级机上使用nokogiri安装时遇到的同样问题.

    /Users/lunchbag/.rvm/rubies/ruby-2.0.0-p451/bin/ruby extconf.rb --with-xml2-include=/usr/local/Cellar/libx/libxml2/2.7.8/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/1.13.1/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib

Gem files will remain installed in /Users/lunchbag/.rvm/gems/ruby-2.0.0-p451/gems/nokogiri-1.6.1 for inspection.

我的configure.log显示以下错误:

configure: error: cannot find sources (entities.c) in /usr/local/lib/node_modules/npm or ..

我已经尝试安装/重新安装/取消链接/重新链接libxml2,libxslt.

还有其他提示吗？谢谢!

使用Homebrew安装库并NOKOGIRI_USE_SYSTEM_LIBRARIES=1在安装gem之前进行设置对我来说是个窍门.

总结:

• 如果以前安装过,请卸载gem:
  $ gem uninstall nokogiri

• 使用Homebrew进行安装libxml2,libxslt并且libiconv:
  $ brew install libxml2 libxslt libiconv

• 安装gem指定要链接的库的路径:
  $ NOKOGIRI_USE_SYSTEM_LIBRARIES=1 gem install nokogiri -- --use-system-libraries --with-iconv-dir="$(brew --prefix libiconv)" --with-xml2-config="$(brew --prefix libxml2)/bin/xml2-config" --with-xslt-config="$(brew --prefix libxslt)/bin/xslt-config"
