I'm having 
[Errno 36] File name too long
issues with 
./pants export
for exporting a virtual environment where wheel filenames become too long, e.g.
Copy code

what's going on with the 
manylinux
versioning being appended repeated?

Dotted wheel tags are a thing: https://peps.python.org/pep-0425/#compressed-tag-sets Are you using ecryptfs home for encryption per chance? If so, the short answer is don't.

I’m not familiar with our disk encryption but we do have something set up. Sounds like I’m out of luck on the dotted wheel tags? What a strange way to tag something
e
Pants and Pex have configurable cache dirs, from phone but you can search knowing that.
@ancient-terabyte-9085 
df -h
is one way to learn more about your mount setup quick.

FWIW: This should be fixed by https://github.com/pantsbuild/pex/pull/2217 When Pex 2.1.143 is released (should be by 8/17) I'll post instructions here to upgrade your Pants config to it.
Ok @ancient-terabyte-9085, to upgrade your Pants setup to use Pex 2.1.143 with the fix, add this to `pants.toml`:
Copy code
[pex-cli]
version = "v2.1.143"
known_versions = [
  "v2.1.143|macos_arm64|7dba8776000b4f75bc9af850cb65b2dc7720ea211733e8cb5243c0b210ef3c19|4194291",
  "v2.1.143|macos_x86_64|7dba8776000b4f75bc9af850cb65b2dc7720ea211733e8cb5243c0b210ef3c19|4194291",
  "v2.1.143|linux_x86_64|7dba8776000b4f75bc9af850cb65b2dc7720ea211733e8cb5243c0b210ef3c19|4194291",
  "v2.1.143|linux_arm64|7dba8776000b4f75bc9af850cb65b2dc7720ea211733e8cb5243c0b210ef3c19|4194291"

Excellent. Thanks for testing that out.
