how I got FlatCAM 8.1 working on OS X [a long time ago — see comment thread for lots of good tips from others!]

install_flatcam.sh

brew update
brew install pyqt geos spatialindex
easy_install pip
pip install virtualenv

cd Development/Others\'/
mkdir FlatCAM
cd FlatCAM
virtualenv env
source env/bin/activate
pip install numpy matplotlib rtree scipy shapely simplejson
# copy contents of FlatCAM_8.1.zip into FlatCAM folder
python FlatCAM.py

Homebrew is how I got it working. It does take several hours.Sent from my iPadOn Jun 17, 2023, at 2:01 AM, dhysuiej ***@***.***> wrote:Re: ***@***.*** commented on this gist.Does anyone know whether a version of FlatCAM compatible with macOS Catalina could be built directly on Github Actions?I'm currently following the steps in this video, but it's taking me too long to install pyqt via homebrew.—Reply to this email directly, view it on GitHub or unsubscribe.You are receiving this email because you commented on the thread.Triage notifications on the go with GitHub Mobile for iOS or Android.

plc help me

if you are using python 3.10+ change import collection in appCommon/Common.py to

import collection.abc
collections.Iterable = collections.abc.Iterable
collections.Mapping = collections.abc.Mapping
collections.MutableSet = collections.abc.MutableSet
collections.MutableMapping = collections.abc.MutableMapping

if you are using python 3.10+ change import collection in appCommon/Common.py to

import collection.abc
collections.Iterable = collections.abc.Iterable
collections.Mapping = collections.abc.Mapping
collections.MutableSet = collections.abc.MutableSet
collections.MutableMapping = collections.abc.MutableMapping

After that I get the error ModuleNotFoundError: No module named 'ezdxf.math.vector'
Module ezdxf is installed

How can I fix it?

Thanks for an reply

After that I get the error ModuleNotFoundError: No module named 'ezdxf.math.vector'

This was fixed on the Beta branch in this commit

I'm currently in the process of getting FlatCAM build with MacPorts.

I finally got it all working, but it will still take some time until I got all newly created port files for flatcams dependencies into shape to get them into the upstream macports repo.

One thing I wanted to share here, though: The problem with

AttributeError: module 'vispy.visuals.markers' has no attribute '_marker_dict' error

is due to a "patch" in appGui/VisPyPatches.py, which has long been available in upstream VisPy. So lines 16-34 in this file can safely be removed and then flatcam also runs with newer (i.e., > 0.9.0) vispy versions.

anyone know about this error ?

I presume you are trying to run flatcam with python 3.12, because FileFinder.find_module, which has been deprecated since python 3.4 and removed in 3.12 (see https://docs.python.org/3.11/library/importlib.html#importlib.abc.PathEntryFinder.find_module).

So you can either switch to python < 3.12 or try to fix that line by using load_spec instead.

Did someone manage to pack flatcam in a standalone app with py2app or pyInstaller? I'm trying to get flatcam work on my Mac (OSX 16.x) but I have no luck. I tried with different python versions but had no luck. I would super grateful if someone could compile flatcam to a standalone application. There is also an icon in .icns format I made from the png logo. Feel free to contact me, I'll share it with you.

Has anyone fixed this? the original code line is module = loader.find_module(name).load_module(name)
i've changed to module = loader.find_spec(name).create_module(name) but it triggers the ModuleSpec Object has no attribute 'create_module'

It likes the find_spec change but not the create_module one

On the off-chance people don't know this:

brew tap tomoyanonymous/flatcam
brew install flatcam-beta
