Describe the bug
I installed pyenv-win in my command prompt and was able to successfully set environment variables. However, when I go to check version of pyenv, it errors out.

To Reproduce
Steps to reproduce the behavior:

1. Go to Command Prompt / Anaconda Prompt
2. Run pip install pyenv-win --target %USERPROFILE%.pyenv
3. Go to PowerShell
4. Run [System.Environment]::SetEnvironmentVariable('PYENV',$env:USERPROFILE + ".pyenv\pyenv-win","User")
5. Run [System.Environment]::SetEnvironmentVariable('path', $HOME + ".pyenv\pyenv-win\bin;" + $HOME + ".pyenv\pyenv-win\shims;" + $env:Path,"User")
6. Close PowerShell, Close Command Prompt / Anaconda Prompt
7. Open Command Prompt / Anaconda Prompt
8. pyenv --version
   'chcp' is not recognized as an internal or external command,
   operable program or batch file.
   'cscript' is not recognized as an internal or external command,
   operable program or batch file.

When I check version of python, it works:
(base) C:\Users\Natalie>python --version
Python 3.7.0

Expected behavior
Running pyenv --version should return the current version of pyenv like what it shows for python.
