Rubyを入れる

RaspbianにRuby入れようとしたらOpenSSL libないって言われたので。

rbenvを入れる

git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile

※追記 .bash_profileじゃなくて.profileに設定

ruby-buildを入れる

git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

Ruby 2.2.0を入れる

hoge@rbp01:rbenv install 2.2.0

The Ruby openssl extension was not compiled. Missing the OpenSSL lib?

怒られた

OpenSSL libがないっぽい、OpenSSLは既にインストールされていたので

sudo apt-get install libssl-dev

もう一度実行
