  open       View a given module in your editor.
  run        Spawns a command installed into the virtualenv.
  shell      Spawns a shell within the virtualenv.
  sync       Installs all packages specified in Pipfile.lock.
  uninstall  Un-installs a provided package and removes it from Pipfile.
  update     Runs lock, then sync.

Steps to replicate

The file “Pipfile” is generated automatically，but it is empty.

I have tried to reinstall the pipenv as follows, but it was still the same.

pip uninstall pipenv pip install pipenv

Please run $ pipenv --support, and paste the results here. Don’t put backticks (`) around it! The output already contains Markdown formatting.

@children1987 Thanks for the information clarifying what is happening.

There exist stale keys in your registry. To fix this,

1. Fully uninstall Python2.7
2. Check the registry with regedit and manually clear the keys of 2.7 at HKCU/Software/Python/PythonCore(or HKLM/Software/Python/PythonCore depending on how you installed Python.

@frostming Thank you so much! I did as your list, everything is OK now.
