Failed to activate virtualenv with pyenv

I run:

pyenv activate new_app

And I get:

Failed to activate virtualenv.

Perhaps pyenv-virtualenv has not been loaded into your shell properly.
Please restart current shell and try again.

I recently made my .bash_profile it contains:

bash-3.2$ cat ~/.bash_profile 
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
exec "$SHELL"
if which pyenv-virtualenv-init > /dev/null; then eval "$(pyenv virtualenv-init -)"; fi

What should I do to properly start virtualenv?

Answer

That

eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

should be in .bashrc, not .bash_profile. The latter is executed only by login shells, the former by all interactive shells.
