can't use pyenv activate a anaconda-virtualenv

[jxxiao]

I use conda create env_tf , but I can't activate it by pyenv activate.

pyenv-virtualenv: version `env_tf' is not a virtualenv

env_tf is a virtualenv created by anaconda.

I can activate it by conda activate env_tf。
But I can not activate it by pyenv activate。

pyenv virtualenv miniconda3-4.3.30 env_miniconda
pyenv activate env_miniconda
remind me :"pyenv-virtualenv: version `env_miniconda' is not a virtualenv"

I know I can activate env_miniconda like this:
conda activate env_miniconda
but before this, I have to change my python to miniconda.So I think it's not a good way to solove this problem.

#290 can't solve my problem.

when I use
brew install --HEAD pyenv-virtualenv
when I activate a virtualenv like this:
pyenv activate virtualenv
remind me :"pyenv-virtualenv: version virtualenv is not a virtualenv"

#290 I can't even use pyenv-virtualenv。
