It fixed and installed after pip install attrdict but I don't usually expect failure to pip install.

But with python 3.10 on my ArchLinux it is raising the following error:

It seems that attrdict is incompatible with python 3.10. This is caused by a change in the collections interface starting with Python 3.10.

[swt2c]

You need attrdict3 not attrdict. Note that it is only actually used on Windows currently, so I submitted a PR to remove it on other platforms, see #2224

[tatarize]

My linux unittest started failing due to that too. I sort of expect those kinks to get worked out. And the wheels really should have deployed I think for my OS but I'm not too worried since it bleeding edge.

[swt2c]

@tatarize, what is your OS and Python version?

[2sn]

@swt2c installing attrdict3 works for me for now. Thanks.

[tatarize]

@tatarize, what is your OS and Python version?

Windows 7. Python 3.8 but I also had unittest in linux fail along the same lines it was trying to install wxPython for a thing it didn't really need it for.

[Flanisch]

I had the same issue on arch linux recently. If for some reason older versions of wxPython with python 3.10 are needed, you can change the import occurrences of from collections to from collections.abc within the attrdict library.

[alexdewar]

It's not only used on Windows, hence why builds are now failing on Linux. At the very least, it is needed when the wheel is built from source (as it always is on Linux). I'm afraid I don't know the inner workings of wxpython better to narrow it down further.

Here is my pip error log:

[swt2c]

There isn't any need to narrow it down further. You need to install attrdict3 in order to build wxPython 4.2.0. In the future, you'll only need it on Windows.

[tatarize]

The objection I had was that Linux stopped working. I had some github Linux thing that required wx for unit tests and it threw that error. It didn't work in my windows7 python3.8 setup either since it demanded the attrdict thing.

With the merge of not requiring this for Linux this might be closable. I'm used to just getting a valid wheels for windows rather than it trying to compile the whole thing that it doesn't seem like it should have thrown that error at me there either. But, that might be fixable and the Windows10/Python 3.10 system had it install without issue.

[tatarize]

I did just remove wx from the linux unittests since they were never used. So I might not be well versed on all the threads of this issue.

[alexdewar]

There isn't any need to narrow it down further. You need to install attrdict3 in order to build wxPython 4.2.0. In the future, you'll only need it on Windows.

But the point is that you don't have a choice but to build it on Linux, so if you run pip install wxpython it currently just errors out. So on Linux it is a required dependency if you want users to be able to actually install wxpython.

[technout]

On Ubuntu 20.04.4 with kernel 5.15

I got almost the same error:

Fixed it with: pip3 install attrdict

[forchtj]

I am getting the same error on CentOS 7.8.2003, python version 3.6.8, wxPython version 4.2.0.

Adding attrdict and/or attrdict3 to my requirements file ahead of wxpython does not solve the issue.

[allenyllee]

@forchtj I have the same error on wine/windows, python version 3.6.8, wxPython version 4.2.0.

But when I downgrade to wxPython 4.1.1, the error was gone.

[alexdewar]

Tbh I'm rather disappointed at the devs' lack of response here.

This breaks things for Linux users -- for example my CI is now failing for a number of projects and the only sensible fix is to pin wxpython to an older version. The offending commit should clearly just be reverted.

[swt2c]

Which offending commit?

[alexdewar]

Thanks for your response! I think this is the one: 2e9169e

If I understand correctly, it removes attrdict3 as a dev dependency for Linux, meaning building wxpython (e.g. when you run pip install wxpython) will fail due to a missing import.

[swt2c]

No, sorry - that FIXES the problem you're seeing.

As a workaround for your CI, you can 'pip install attrdict3' before trying to install wxpython.

[alexdewar]

So just to be clear, the intention of wxpython's developers is that pip install wxpython should be guaranteed to fail on Linux unless they execute another command beforehand?! That's a pretty user-hostile design 😞

What's so important about that commit that it's worth breaking your users for?

[swt2c]

Sorry, but you're misunderstanding the problem. When you're running pip install wxpython what you're getting DOES NOT include that commit!

[greyltc]

I have the same problem today. I was expecting pip install wxpython to work. This comment matches my exact experience: #2225 (comment)

[greyltc]

I guess building the 4.2.0 release is broken under modern linuxes because of the attrdict module import. Deleting

Phoenix/buildtools/config.py

Line 30 in b567d1e

from attrdict import AttrDict

seems to solve the problem for me and it looks like that's already been done in the main branch via 2e9169e
So those wanting to build 4.2.0 (the latest stable release as of this writing) need to either patch it before building or wait for a new release that rolls in the fix from 2e9169e.

[tatarize]

I'm pretty sure the commit you cited is to fix the issue. What you actually want is the releases of 4.2.0-post1 with that commit in place. Such that installs in Linux are not strange and crashing. We need the pip version to actually work. We don't want to wait a year for that to happen.

[RobinD42]

This issue has been mentioned on Discuss wxPython. There might be relevant details there:

https://discuss.wxpython.org/t/error-trying-to-pip-install/36381/2

[matthew-mcallister]

It's not possible to install projects that depend on wxPython through pipx due to this bug.

[alexdewar]

I've currently got the version of wxpython in my pyproject.toml pinned to <4.2.0 as a workaround.

It's been an issue for more than six months now though 😞

[JessicaTegner]

A fix that worked for me was.

Open "Developer Command Prompt for VS 2022"
pip install attrdict3
pip install requests
pip install wxpython (this took around 5-10 minutes on my computer because it builds everything from source)

[Dyrimon]

Hi, I've installed requests, attrdict and attrdict3 successfully. Still can't install wxpython.

i, I've installed requests, attrdict and attrdict3 successfully. Still can't install wxpython.

You need to uninstall attrdict and keep only attrdict3.
Both projects are the same, in the sense that they both create python package attrdict. So installing both projects will result in only one of them being loaded, in your case attrdict instead of attrdict3.

attrdict3 (https://github.com/pirofti/AttrDict3) is a forked version of the original attrdict project (https://github.com/bcj/AttrDict). The fork was created when the original project stopped being maintained. attrdict3 includes recent updates that allow it to work in more recent versions of python. In particular, the original project will not work with Python 3.10 and later because of changes in the collections library that happened in 3.10.

[oyvindln]

@swt2c Would it be possible to put a point/patch release with the dependency changed to attrdict3 on pip so we don't have to workaround this while waiting for the next version?

[swt2c]

@oyvindln unfortunately, I don't have permissions to create new releases, only @RobinD42 does. Really a more helpful solution would be for Robin to make new wheels for Python 3.11 and 32-bit Windows, which would solve most of these problems. Most people probably do not want to build wxPython from scratch, but just install it.

[tatarize]

Yeah, I actually sort of expected a -Post1 release a while back. I think it's probably fixed but still is causing wxPython to fail kind of universally. I've had to tell more than a couple people to install with ==4.1.1 since it was a bit screwy to get around this thing.

[heiko-weber]

on my debian 12 system there were the "gtk+ dev" missing
the attrdict was just confusing

sudo apt-get install build-essential libgtk-3-dev
found here -> #1831

some other issues seems to be to have wheel installed before.

[tatarize]

With the release of wxPython 4.2.1, automatic installation is no longer failing.
