EasyABC stopped working after Linux update

[Ray Chandler]

EasyABC had been working fine under Manjaro Linux, but after a recent Manjaro update it fails to open. I tried a clean re-install of EasyABC but it failed and I get the following terminal message:

[ray@ray-dell ~]$ easyabc
14:20:39: Warning: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1014,wx containers,compatible with 2.8),
and wxPython used 3.0 (wchar_t,compiler with C++ ABI 1016,wx containers,compatible with 2.8).
Traceback (most recent call last):

    collections.MutableMapping.register(ParseResults)
AttributeError: module 'collections' has no attribute 'MutableMapping'

I raised it on the Manjaro forum but got no solution. Any help appreciated.

Comment from Manjaro team:
"It must be adapted to Python 3.10. The collections module does not provide MutableMappings anymore. It was deprecated a while ago, the developers of EasyABC must change their code."

Any chance of this happening?

Hello Ray,

In a next version of EasyABC this will be fixed.

For the time being you could try the following:
cd /opt/easyabc
rm pyparsing.py
sudo apt install python3-pyparsing
python3 easy_abc.py

Thanks JW - great news that this will be fixed in the next version.
EasyABC is an excellent facility and I'm looking forward to getting it back.
In the meantime I've tried your temporary fix above and it removed the old pyparsing.py but at the install command I get "Error: target not found: python3-pyparsing".
EasyABC now opens (it didn't before this) but the "Musical score" panel remains empty and doesn't show the tune of the abc file below it. In the "ABC code" panel I can edit the tune, transpose it, etc, but nothing appears in the score panel.

You could also use pip to install pyparsing.
pip install pyparsing

Some distributions still have both Python 2 and Python 3. In that case use:
pip3 install pyparsing

pyparsing is installed, but the problem remains:
