Failed to build retworkx
ERROR: Could not build wheels for retworkx which use PEP 517 and cannot be installed directly

[mtreinish]

Based on the log I assume your running on macOS < 10.13. There was already a packaging bug reported on retworkx for macOS 10.9 to 10.12 there Qiskit/rustworkx#62. I was planning to push out a released package today to get that fix out (After Qiskit/rustworkx#69 merges). I'll comment here when that is up on pypi so you can try installing again.

[mtreinish]

ok, the 0.3.4 release and all the wheels are up on pypi (except for armv8/aarch64 which the travis environment is currently broken for): https://pypi.org/project/retworkx/0.3.4/#files Give installing a try again (and maybe use the -U flag on pip so it installs the latest version) If you're on an older version of macOS then this should fix the issue for you and just install the precompiled binary hosted on pypi now

[wade-liwei]

Thank you.
Yea, my mac OS is 10.12.6;

I will try it again.

[nonhermitian]

@wade-liwei any word on whether the update solved your problem?

[wade-liwei]

@nonhermitian

yea, the update solved my problem.
Thanks @nonhermitian and @mtreinish
