[Ubuntu] Fail to run from source - fixed for next version

[Andre Lewis]

Cloned from the beta branch, ran setup_ubuntu.sh and it mostly completes, however there is no easy_install built in with python 3.8. Running pip install setuptools also doesn’t install it nor does the version installed by using the Ubuntu version:

> sudo apt install python-setuptools
python-setuptools is already the newest version (44.0.0-2).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
> sudo -H easy_install -U distribute
sudo: easy_install: command not found

Commenting out the easy_install line works, and running make install installs it locally. However running it fails with:

./flatcam-beta
Traceback (most recent call last):
  File "/home/ninjaandre/flatcam/assets/linux/../..//FlatCAM.py", line 58, in <module>

    markers._marker_dict['++'] = cross_lines

I’m pretty sure all the dependencies are there:

Hi,

The easy_install package is not needed, it is a leftover from the older versions of FlatCAM. In the next version will no longer be there.
Regarding the vispy issue, if you are using the Beta branch from this repository try to install an older version of this package, maybe 0.7.

BTW, the latest versions of VisPy (0.9.1 and 0.9.2) bring a drastic performance degradation (more than 400% performance drop compared with 0.9.0).

[Andre Lewis]

Ok, that actually worked, using vispy 0.7! Thanks!

Removing the new package:

sudo pip uninstall vispy
Found existing installation: vispy 0.9.2
Uninstalling vispy-0.9.2:
  Would remove:
    /usr/local/lib/python3.8/dist-packages/vispy-0.9.2.dist-info/*
    /usr/local/lib/python3.8/dist-packages/vispy/*

and adding it back in:

sudo pip  install vispy==0.7

Although sudo may be unnecessary.

I faced the same issue with 8.994 on linux mint/Ubuntu 18.04 and installing vispy 0.7 fixed it for me too

[Azby Cxdw]

Hi,

I tried to install “FlatCAM_beta_8.994_sources.zip“ in my new ubuntu 22.04 and had quite some issues. but finally I got there. I left below in case someone faces the same issues.

First, no idea about python so… well thanks internet i got all i needed.

1.USER@USER_LAPTOP:~/Downloads/FlatCAM_beta_8.994_sources$ make install_dependencies

installed a lot of things, so i thought it was going to be first time right. Wrong. Got below msg which in the end seems to be only a warning.

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv
sudo: easy_install: opdracht niet gevonden
make: *** [Makefile:6: install_dependencies] Fout 1

Tried to run FlatCam. USER@USER_LAPTOP:~/Downloads/FlatCAM_beta_8.994_sources$ python3 FlatCAM.py and got below

Traceback (most recent call last):
File "/home/USER/Downloads/FlatCAM_beta_8.994_sources/FlatCAM.py", line 6, in <module>

from appCommon.Common import LoudDict
File "/home/USER/Downloads/FlatCAM_beta_8.994_sources/appCommon/Common.py", line 88, in <module>
class LoudUniqueList(list, collections.MutableSequence):

surfing internet I found, this post that helped me. From that point on, I started replacing collections by collections.abc every where there was an error by executing the program.

Second error:

USER@USER_LAPTOP:~/Downloads/FlatCAM_beta_8.994_sources$ python3 FlatCAM.py

Which solution is in this very forum Link.

Third error:

Which solution was: USER@USER_LAPTOP:~/Downloads/FlatCAM_beta_8.994_sources$ pip install pyserial

Fouth error:

Finally it runs

Best regards and thanks for the nice tool

[Hans Boot]

With the latest pip (pip 22.3.1 on python 3.10), “pip install vispy==0.7.3” breaks:

vispy-0.7.3.tar.gz has inconsistent version: expected ‘0.7.3’, but metadata has '0.0.0'

You must therefore use:

pip install --use-deprecated=legacy-resolver --user vispy==0.7.3

but then you have

% pip freeze | grep vispy

vispy==0.0.0

which breaks other things, making all this rather complicated. Is it possible to upgrade to the latest vispy?

‌

[Marius Stanciu]

Hello,
The reason for those issues is that I have made some contributions to the vispy package and some features are now in vispy and therefore FlatCAM no longer requires some of the patches that were made to vispy.

The development for FlatCAM beta (EVO) is on hold currently, I have some rather big changes in my life, once those will settle I will start allocating time again for this project.
Best regards,
Marius

[Hans Boot]

Take your time. You’ve given a lot already. Life has priority. Now the workaround is logged, people can continue using it, so nothing is blocked.

[VINICIUS GARCIA]

Is there any solution for this item, I have the same problem as above with installation Vispy and Vispy=7.0.0

In fact, I commented the 2 lines that request this command and Flatcam worked, but I don't know how this could damage the program.

[Stanislav Granovskiy]

@Azby Cxdw Did you tryed to generate and save DRILL’s job? It’s not works after i did all the steps you described. :(

[Azby Cxdw]

@Stanislav Granovskiy , yes, it does work for me, you can run the tool from the console and post the error.
