zbentley opened a new issue #11203:
URL: https://github.com/apache/pulsar/issues/11203
**Describe the bug**
The compilation of the Python binary artifact for the 2.8 client library
appears to have been performed incorrectly. The client currently tries to
dynamically link against libraries that don't exist, which causes `import
pulsar` to fail.
The library has static (absolute) linker paths baked in which appear to
correspond to paths that were only present on the environment on which the
current distribution of the binary was originally compiled before being
uploaded.
**To Reproduce**
Steps to reproduce the behavior:
1. On Mac OS Big Sur, create a python environment using either Python 3.8 or
Python 3.9 (I've reproduced on both). I used `pyenv` for 3.8, and Homebrew for
3.9.
2. In that environment, do `pip install pulsar-client==2.8.0`
3. Launch `python` and run `import pulsar`
4. See error:
```
>>> import pulsar

**Expected behavior**
A clear and concise description of what you expected to happen.
**Desktop (please complete the following information):**
- OS: Mac OS Big Sur
**Additional context**
The error is caused by absolute (rather than relative) linker paths:
