[Rails][CentOS]gemのnokogiriインストールでエラー ERROR: Error installing nokogiri:

By On 2015年5月6日 · Leave a Comment · In CentOS, Rails

はじめに

bundle installでgemのnokogiriがinstallできていませんとエラーがでました。
直接nokogiriをinstall指定していませんでした。※これはインストールするgem内でnokogiriを使っているgemがあったのかと思います。
その後、nokogiriをyumでインストールしましたがエラーが出たため、対応策をメモしておきます。

インストール実行

Building native extensions. This could take a while…

************************************************************************
IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.2
with the following patches applied:
– 0001-Revert-Missing-initialization-for-the-catalog-module.patch
– 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

gem install nokogiri — –use-system-libraries
[--with-xml2-config=/path/to/xml2-config]
[--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

bundle config build.nokogiri –use-system-libraries
bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

対応策

エラー内に改善案が書いてありました。
必要なライブラリをインストールし再度nokogiriを指定方法によりインストールします。これで手元環境ではエラーなく成功しました。

$ sudo yum -y install libxml2 libxslt libxml2-devel libxslt-devel
$ gem install nokogiri -- --use-system-libraries
