MacにRubyのrbenvを構築する

古渡 晋也

WRITTEN BY古渡 晋也

はじめに

こんにちは。インフラエンジニアレベル001のf_prgです。
Ruby徹底攻略 (WEB+DB PRESS plus) という本を購入して、Macにrbenvの環境を作りましたので、その際の実行ログです。

構築

インストール

[17:57:57][f_prg@mba:~]# brew install openssl libyaml readline gmp
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/openssl-1.0
######################################################################## 100.0%
==> Pouring openssl-1.0.1g.mavericks.bottle.tar.gz
==> Caveats
A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, so it was not symlinked into /usr/local.

Mac OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.

The OpenSSL provided by OS X is too old for some software.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/openssl/lib
    CPPFLAGS: -I/usr/local/opt/openssl/include

==> Summary
:beer:  /usr/local/Cellar/openssl/1.0.1g: 429 files, 15M
Error: libyaml-0.1.5 already installed
To install this version, first `brew unlink libyaml'
Warning: It appears you have MacPorts or Fink installed.
Software installed with other package managers causes known problems for
Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again.
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/readline-6.
######################################################################## 100.0%
==> Pouring readline-6.3.5.mavericks.bottle.tar.gz
==> Caveats
This formula is keg-only, so it was not symlinked into /usr/local.

OS X provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/readline/lib
    CPPFLAGS: -I/usr/local/opt/readline/include

==> Summary
:beer:  /usr/local/Cellar/readline/6.3.5: 40 files, 2.1M

まとめ

簡単にできました。
今後、OS入れ替えた際にまた必要になりそうですね。
次回は、Centos版も業務でやったので投稿しようと思います。
