rbenvでRuby 2.5.0-devをインストールする

More than 3 years have passed since last update.

動作確認がしたかったので、手近な環境でインストールしてみたら、少々躓いたのでメモします。

  • OS: CentOS 6.8
# ruby-buildを更新
cd ~/.rbenv/plugins/ruby-build/
git pull origin master

# 2.5.0-dev をインストール
rbenv install 2.5.0-dev

# autoconf command not found
# -> autoconf をインストール
sudo yum install autoconf

# 再度 2.5.0-dev をインストール
rbenv install 2.5.0-dev

# Autoconf version 2.67 or higher is required
# -> http://ftp.gnu.org/gnu/autoconf/ より最新版をインストール
sudo yum remove autoconf
wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz
tar zxfv autoconf-2.69.tar.gz
cd autoconf-2.69
./configure
make
sudo make install

# 再度 2.5.0-dev をインストール
rbenv install 2.5.0-dev

# make: bison: Command not found
# -> bison をインストール
sudo yum install bison

# 再度 2.5.0-dev をインストール
rbenv install 2.5.0-dev

# インストール成功!
rbenv global 2.5.0-dev
ruby -v # ruby 2.5.0dev (2017-04-11 trunk 58313) [x86_64-linux]
