liblo/cython issues

[kodokoto]

Hello, I successfully installed cython via pip3 and liblo via brew as recommended in the readme, and I also installed pylive via pip3.

But when I try running setup.py I get this error:

WARNING: The wheel package is not available.

During handling of the above exception, another exception occurred:

[kodokoto]

Fixed it using

python3 -m pip install cython
python3 -m pip install pylive

[ideoforms]

Thanks for the feedback @kodokoto!

Just so I can better understand the scenario for future reference, would you mind pasting the output of the following commands for me?

ls -al `which python3`
ls -al `which pip3`

Thanks.

[kodokoto]

ls: which python3: No such file or directory

~
➜ ls -al 'which pip3'
ls: which pip3: No such file or directory

There is a big chance that it stems from my python installation being weird.

[ideoforms]

I think you're probably right. But, it's quite easy to end up with a weird Python install, so I'm keen to do everything I can to understand and guard against it.

Those quotes should be backticks (`), not single quote marks (') - mind copy and pasting the original commands? You should get an output that shows where the python3/pip3 symlinks point to.

[kodokoto]

Ah my bad that is the output

➜ ls -al `which pip3`
lrwxr-xr-x  1 modii  admin  35 11 Apr 11:30 /usr/local/bin/pip3 -> ../Cellar/python@3.9/3.9.4/bin/pip3

~
➜ ls -al `which pip3`

lrwxr-xr-x  1 modii  admin  35 11 Apr 11:30 /usr/local/bin/pip3 -> ../Cellar/python@3.9/3.9.4/bin/pip3

[ideoforms]

Aha, I think I can see the issue and it is something that I should fix.

Can you run one last one:

ls -l `which python`

[kodokoto]

Yes, sorry for the late reply

➜ ls -l `which python`

lrwxr-xr-x  1 root  wheel  75  1 Jan  2020 /usr/bin/python -> ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7

[ideoforms]

That was really useful, I've fixed the setup.py to ensure it always uses the python3 binary to ensure the above doesn't happen again. Thanks for taking the time to help!
