Install asking for python3 while using python 2

[Psy-Fer]

Hello,

I am following on from this issue over at circtools ( dieterich-lab/circtools#82 )

So I made a python2 venv, and while trying to install, it's now telling me I need python 3?

I've dropped the stacktrace below.

Any help would be appreciated.

Cheers,

Hmm, it seems installing FUCHS on the same environment first, solves the issue. Though I imagine this isn't the intended method.

[Psy-Fer]

Also, while trying to use python scripts/DCC

I get the following error

python scripts/DCC -h
Traceback (most recent call last):
File "DCC", line 5, in
DCC.main.main()
AttributeError: 'function' object has no attribute 'main'

I changed DCC to the following, and it works fine

#!/usr/bin/env python2

import DCC.main

DCC.main()

[Psy-Fer]

same goes for FUCHS, the script tries to open main, but there is no main in the FUCHS directory, only FUCHS.py, which has a main() function.

changed it to

#!/usr/bin/env python

import FUCHS.FUCHS as fu

fu.main()

as no FUCHS given

Hi @Psy-Fer,

I am wondering why DCC tries to install numpy 1.17.0. The setup files specifically lists < 1.17.0 as requirement. It is in the master branch, therefore git you do a git clone, that change should already be in there. Seems to be pulled in by pandas?

Could you start with a clean venv and install 1) only DCC and then 2) in another new venv just FUCHS to be able to see where these issues arise?

Cheers,
