pgのインストールで失敗

bundle installが失敗します。

Installing pg (0.15.1)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

checking for pg_config… no
No pg_config… trying anyway. If building fails, please try again with

checking for libpq-fe.h… no
Can’t find the ‘libpq-fe.h header
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

Gem files will remain installed in /home/vagrant/.rbenv/versions/2.0.0-p247/lib/ruby/gems/2.0.0/gems/pg-0.15.1 for inspection.

An error occurred while installing pg (0.15.1), and Bundler cannot continue.
Make sure that `gem install pg -v ‘0.15.1’` succeeds before bundling.

pgのところで失敗します。

postgresql-libsをインストールする

CentOSでpostgresql-libsをインストールするといいみたいです。

sudo yum install postgresql-devel
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: www.ftp.ne.jp
* extras: www.ftp.ne.jp

略

Installed:
postgresql-devel.x86_64 0:8.4.18-1.el6_4

Dependency Installed:
postgresql.x86_64 0:8.4.18-1.el6_4 postgresql-libs.x86_64 0:8.4.18-1.el6_4

Complete!

この後にbundle installしたらうまくいきました。

まとめ

CentOSでpgをいれるときはpostgresql-libsを入れるといいようです(☝ ՞ਊ ՞)☝
