vagrant plugin install hostmanager実行時のnokogiriインストールエラーの解決

マルチドメインのテストがしたくて、vagrantでホスト名を指定するにはどうすればよいか調べた。vagrant-hostmanagerというプラグインが使えそうなのでインストールしてみたところ、nokogiriインストールエラーが発生したので、解決方法をメモする。

vagrant upするときに、/etc/hosts を書き換えるみたい。

インストール時のinstall nokogiriのエラー

vagrant plugin install vagrant-hostmanager

上記コマンドで簡単にインストールできるかとおもいきや、nokogiriのインストールでコケる。

Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:

An error occurred while installing nokogiri (1.6.6.2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.6.2'` succeeds before bundling.

libiconv is missing. Please locate mkmf.log to investigate how it is failing.  あたりのエラーから、libiconvのインストールが出来てなさそうと当たりをつけて調べてみた。

以下を参考に、brew install, brew linkの後、パラメタを指定して、gem install nokogoriを試すと、成功した。

別のプラグインを入れたらvagrantが壊れたので、結局vagrantも最新化した

以下のサイトから、最新版を入れなおした。 http://www.vagrantup.com/downloads
