I tried to install Python using pyenv but came across the following error:
vagrant@vagrant-ubuntu-trusty-64:~$ pyenv install 2.7.8 perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LC_CTYPE = "UTF-8", LANG = "en_US.UTF-8" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C").
For those which are unset, set the environmental variables in .bashrc or .bash_profile.
export LANGUAGE=en_US.UTF-8 export LC_ALL=en_US.UTF-8
Re-login and try again.
