I'm trying to install multicell and in the process, I'm trying to install OpenAlea. However, I'm having the following issue with the 'python multisetup.py develop --user'. The issue is as follows:

'Error processing line 1 of /Users/gweeish/.local/lib/python3.7/site-packages/OpenAlea.SConsX-nspkg.pth:

Any help would be greatly appreciated.

Thank you!

@gweeish I think the problem stems from the fact that you are using Python 3, while multicell was made for Python 2.

That's because 5 years ago, when multicell and openalea were made, Python 2 was still very common (if not the most common), but this is no longer the case, and I haven't worked on this project since then.

What OS are you using? Are you able to install Python 2?

Hi,

Thank you for getting back to me. I am able to run Python 2 but am now running into this issue while installing openalea using the multisetup.py script:

NameError: global name 'Multisetup' is not defined

Thank you.

Sorry, it looks like things changed a lot since I wrote the library.
I will need to put together new install instructions.
It might take a while, because the distribution methods of some of the dependencies seem to have changed.

Hi @jldinh ,

Thank you for letting me know. I will definitely be watching this space. =)

Hi @gweeish ,

I just updated the install instructions with specific git commits to checkout, to make sure you have the same versions as I was using when the library was made.

I also provided a new download link for vplants, as the original went down.

Let me know if you encounter other issues.
