我无法安装 Nokogiri.这已经让我负担了一段时间了.我也通过 MacPorts 和 Homebrew 安装了依赖项.

I can't get Nokogiri to install. This has been taxing me for a while now. I've installed the dependencies via MacPorts and Homebrew as well.

我有一种感觉，正确的目录没有相互指向?但不知道如何修复.

I've got a feeling the right directories are not pointed to each other? But haven't a clue how to fix.

推荐答案

在 Mavericks 中，使用 Homebrew 安装库并在安装 gem 之前设置 NOKOGIRI_USE_SYSTEM_LIBRARIES=1 对我有用.

In Mavericks, installing the libraries with Homebrew and setting NOKOGIRI_USE_SYSTEM_LIBRARIES=1 before installing the gem did the trick for me.

总结:

• 如果之前安装过，请卸载 gem:
  $ gem 卸载 nokogiri

使用 Homebrew 安装 libxml2、libxslt 和 libiconv:
$ brew install libxml2 libxslt libiconv

Use Homebrew to install libxml2, libxslt and libiconv:
$ brew install libxml2 libxslt libiconv

安装 gem，指定要链接到的库的路径:
$ NOKOGIRI_USE_SYSTEM_LIBRARIES=1 ge​​m 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"

Install the gem specifying the paths to the libraries to be linked against:
$ 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"
