pipsi list fails before first install

[lofidevops]

Steps to reproduce:

• Install pipsi
• Do not install any packages yet
• pipsi list

What should happen:

• Returns empty list

What happens instead:

Packages and scripts installed through pipsi:
Traceback (most recent call last):
  File "/usr/bin/pipsi", line 11, in <module>
    load_entry_point('pipsi==0.9', 'console_scripts', 'pipsi')()
  File "/usr/lib/python3/dist-packages/click/core.py", line 722, in __call__
    return self.main(*args, **kwargs)

    rv = self.invoke(ctx)

    return f(get_current_context().obj, *args, **kwargs)
  File "/usr/lib/python3/dist-packages/pipsi.py", line 416, in list_cmd
    for venv, scripts in repo.list_everything():
  File "/usr/lib/python3/dist-packages/pipsi.py", line 307, in list_everything
    for venv in os.listdir(self.home):
FileNotFoundError: [Errno 2] No such file or directory: '/home/user/.local/venvs'

Notes:

• If I install a package and then uninstall it, an empty list is returned, as expected.

• Ideally it would return something more descriptive in both cases:

Packages and scripts installed through pipsi:
  None

• Version details:

$ pipsi --version                                                                                                                                                   
pipsi, version 0.9, python /usr/bin/python3

This seems to be fixed on master.

I recently started a project called pipx that combines pipsi's functionality with npx's. Running pipx list after initial install yields

>> pipx list
venvs are in /Users/user/.local/pipx/venvs, symlinks to binaries are in /Users/user/.local/bin
package pipx 0.0.0.5, symlinks to binaries available: pipx

Would love to hear what you think! https://github.com/cs01/pipx

EDIT: Actually, this error is still being thrown. I'll open a new issue, as I believe my bug is different. Apologies for the noise.

I've just installed pipsi on a new machine, and I am seeing a similar error (but slightly different).
