Allow other ways to install cadquery

[rowanG077]

I have had nothing but trouble with conda. Everytime I have to reconfigure my machine I basically have to take a day to get conda working. Is there a possibility to move away from it and just starting using pypi?

[adam-urbanczyk]

I don't think it is realistically an option. Pip does not really support binary depandancies like oce. What is exactly the issue with conda? It works flawlessly on ci so I'm surprised that you are having difficulties with it. Would providing a docker image or a custom anaconda installer help?

[rowanG077]

I think I have installed conda 5 times in total just to use cadquery. Out of those 5 times only once it worked out of the box. One of the times was on windows where it currently still isn't working. On my current OS conda doesn't work at all which means I currently run a Ubuntu VM just to be able to use cadquery. Conda to me is incredibly brittle software so I would really just prefer a normal environment.

@rowanG077 sorry to hear that. If you are willing to share what does not work I could maybe help. I had success following those instructions:
https://docs.anaconda.com/anaconda/install/silent-mode/

@adam-urbanczyk The problem with conda is that it pollutes the environment. I just removed it (again) because it was breaking everything else python-related on my machine in very pervert ways.

Docker might be A solution to this. It's should be much easier to use for non-python developers, too.

I'm working on getting a nix environment with cadquery and cq-editor going. Don't have it working yet though.

@adam-urbanczyk A docker image would really help I guess. But it just seems really to extreme to resort to package managers which take over your entire system or having to run an entire second system just to be able to run a piece of software.

@rowanG077 Feel free to look at my nixpkgs fork: https://github.com/gebner/nixpkgs/commits/cadquery CQ-editor doesn't work with the upstream pythonocc, so you might need to change the pythonocc-core sources to https://github.com/CadQuery/pythonocc-core/

@rowanG077 @ilya-epifanov assuming you are on Windows could you try the following way of installing miniconda:

start /wait "" Miniconda3-latest-Windows-x86_64.exe /InstallationType=JustMe /RegisterPython=0 /S /D=%UserProfile%\Miniconda3

In general I use the InstallationType=JustMe and RegisterPython=0 options and I have never experienced issues you are describing.

It runs fine at my Laptop (Win10 x64), too. The advantage of Conda is that you can create different environments (cqgui in the case of CQ-Editor) with different package versions.

I've created and update.cmd which I use to start CQ-Editor while keeping up-to-date with the sources:

@echo off
git fetch upstream
git checkout master
git merge upstream/master
conda env update -f cqgui_env.yml -n cqgui --prune
conda activate cqgui
python run.py
conda deactivate

@gebner Thank you! I got cadquery working in a nix environment now by using part of your commits as a reference. Are you planning on upstreaming? If not I will try to get cadquery and CQ-editor into nixpkgs.

@adam-urbanczyk
Isn't it possible to package binary dependencies with pypi? I thought that stuff like python-opencv delivers the opencv binaries with the package itself. Wouldn't this be possible for cadquery as well?

@rowanG077 Not at the moment, feel free to submit a PR to nixpkgs.

I'm feeling like docker-on-conda is the right answer. Conda works well when you want full control and full integration into your environment, and for greenfield installation. Docker works well when you want no muss and fuss just works install that disrupts nothing. So I think the best option is the existing conda based packages, with an additional docker container that has cq already installed (via conda of course)

@rowanG077 @ilya-epifanov any updates on trying the local install?

@rowanG077 yes it is indeed possible to include binary dependencies in a wheel. It is not really practical though, especially for a project with so complex dependencies. If you don't believe me, take a look inside of the wheel that the project you mentioned is providing.

@dcowden agreed. I'll close this issue and open a specific one for docker image. It would be great if someone from the community could pick it up - I don't have the bandwidth and experience.
