Nokogiri在bundle安装(OSx Mavericks)时发生错误

Question

我是rails新手，我不明白为什么Nokogiri不想安装，而我试图捆绑安装:

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.

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。

我尝试这个，从另一个stackoverflow线程:

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"

And:

This could take a while...

我不知道该怎么做…谢谢我的mac: Macbook pro retina 15版，mavericks版

Answer 1

在$ brew install libxml2 libxslt libiconv之后我使用

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

对我很有效。您可以尝试一下，但是要将库的版本更改为您的版本。

Answer 2

我在约塞米蒂国家公园，我想这可能会有帮助。上面的解决方案对我不起作用，但后来我意识到有几个目录不知何故被移动到它们自己

——with-xml2-include =/usr/地方/地窖/libxml2/2.9.2/include/libxml2 libxml /

——with-iconv-lib =/usr/地方/地窖/libiconv/1.14/lib/自由

所以它可能值得检查所有的目录，如果有人仍然有问题(我不认为我把文件那样，但这是完全可能的)

我使用的完整命令:

gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.2/include/libxml2/libxml——with-xml2-lib=/usr/local/Cellar/libxml2/2.9.2/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/lib

Answer 3

在Redhat linux 6中也有同样的问题

你需要安装libxml2 &Libxml2-devel和libxslt &libxslt-devel .

{你需要安装libgcrypt &libgscript -devel，因为它是安装以上包所必需的}

确保安装最新版本。如果包已经存在，那么您需要升级这些包。只使用

rpm -uvh——replacefiles {your_packagename.rpm}

希望它有帮助。如果你需要更多的帮助，请评论。
