やること

GEM_HOME を指定した時は、PATHも通しておく

~/.bash_profile
export PATH="$HOME/.rbenv/bin:$GEM_HOME/bin:$PATH"

起きた症状

bundle コマンドがないと言われる

$ bundle list
-bash: bundle: command not found

ruby -v と rails の ruby が違うバージョンになる

$ ruby -v
ruby 2.3.1p112

ちゃんと最新版のrubyなのだが、rails が起動しない。

$ rails

    Rails 5 requires Ruby 2.2.2 or newer.

    You're running
      ruby 2.0.0p648 

    Please upgrade to Ruby 2.2.2 or newer to continue.
