Issue with llvmlite about orbitdeterminator

[astrojuanlu]

The most recent version of llvmlite does not ship wheels for Python 3.5, as you can see here:

https://pypi.org/project/llvmlite/0.32.1/#files

Therefore, it downloads the source distribution and tries to compile it against a system LLVM, which you don't have (No such file or directory: 'llvm-config').

Ways to fix it:

• Install llvmlite with conda (you already figured that out)
• pip install llvmlite --prefer-binary (you will need a modern pip version for this)
• Upgrade to Python 3.6+

Also, the Python ecosystem is moving away from setup.py and I'd recommend you to do pip install . instead (notice the final dot).

Can't we update the setup.py with the latest?(i can create a pull request)

and how pip install . will be helpful ?

[astrojuanlu]

Updating setup.py with the latest won't help: precompiled wheels for llvmlite are not available for old Python versions. Yes, Python 3.5 is old already, it's End Of Life since last November.

Try creating a new conda environment, upgrade pip, and do pip install . --prefer-binary. It will work.

In any case, this is not an orbitdeterminator bug.
