pipenv --venv takes 0.5 sec

[jabbalaci]

pipenv --venv is quite slow:

$ time pipenv --venv
...
real    0m0.496s
user    0m0.450s
sys     0m0.046s

Why is it so slow? Is there a way to speed it up?

Why is it so slow?

Because the implementation is not optimal.

Is there a way to speed it up?

Yes.

Is there a lot of time available to invest on it?

Not really.

Do lend a hand if you’d like to.

This is fixed in #2485 --

Thank you, it's fixed now. Here are my results:

Before:

$ time pipenv --version
pipenv, version 2018.6.25

real    0m0.486s
user    0m0.456s
sys     0m0.030s
=======================================================================
$ time pipenv --venv
/home/jabba/...

real    0m0.485s
user    0m0.455s
sys     0m0.030s

After:

$ time pipenv --version
pipenv, version 2018.7.1

real    0m0.111s
user    0m0.101s
sys     0m0.010s
=======================================================================
$ time pipenv --venv
/home/jabba/...
