#2023 A loose layout, venv-with-symlink PEX creates brittle symlinks Issue created by thejcannon Pex version

2.1.113

I found this through Pants, but ultimately seems like a PEX issue/fix.

$ pex --no-venv-copies --layout=loose --venv prepend awscli --script aws -o  awscli.pex
$ python awscli.pex help
<help output>
$ mv awscli.pex awscli2.pex/
$ python awscli2.pex

In Pants-land, this manifests as being a symlink to an ephemeral Pants sandbox which has since gone bye-bye. * * * What I might expect is that on first run, the wheels get copied into the PEX root and then the venv symlinks to the extracted wheels in the pex root so moving/deleting the original pex doesn't invalidate the venv. pantsbuild/pex
