ruby-on-rails - 捆绑安装时 Nokogiri 发生错误 (OSx Mavericks)

Question

我是 Rails 的新手，我不明白为什么 Nokogiri 在我尝试捆绑安装时不想安装:

barnab21:sample_app barnab21$ sudo bundle install
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as
root will break this application for all non-root users on this machine.

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/nokogiri-1.6.2.1 for inspection.

An error occurred while installing nokogiri (1.6.2.1), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.2.1'` succeeds before bundling.

我试试这个:

 $ xcode-select --install

然后 gem install nogoriki，但这不起作用。

我从另一个 stackoverflow 线程尝试这个:

如果以前安装过，请卸载 gem:

$ gem uninstall nokogiri

如果需要，使用 Homebrew 安装 libxml2、libxslt 和 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"

和:

This could take a while...

我不知道该尝试什么...谢谢我的 mac:Macbook pro retina 15，小牛

在$ brew install libxml2 libxslt libiconv之后我用了

gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.7.8/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.7.8/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26 --with-iconv-include=/usr/local/Cellar/libiconv/1.14/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.14/lib

它对我有用。您可以尝试，但将库的版本更改为您的版本。
