Pylint throws an error when evaluating import packages.

[Grimler91]

Please use the bug report template. How can I reproduce the issue?

[linusjf]

All you have to do is run pylint against namedtuple.py to get the error. The version number for pylint is specified in the referenced bug report.

[Grimler91]

I don't get any error on my aarch64 device. So, again, please use the bug report template and provide the requested information, like the output of termux-info.

If you still need the rest, you will have to wait since I'll have to re-collate and aggregate the information and then put it in the desired format. All this from my phone.

[ghost]

No errors, at all:

Since my CPU arch and repo versions same as yours, I guess problem is either in device or your Termux installation. Otherwise bug will be reproducible on all devices with similar properties.

If you still think that config file is correct, post it here either via attachment or with

curl --upload-file ~/.pylintrc https://linx.li/upload/

[linusjf]

It's the same file I've been using for a couple of months now. It was generated via pylint itself. It's not hand-crafted.

https://github.com/Fernal73/LearnPython3/blob/master/.pylintrc

[ghost]

With pylintrc from https://github.com/Fernal73/LearnPython3/blob/master/.pylintrc it works fine. So config should not be a problem.

[linusjf]

Are you expecting me to debug this? I'd rather not run pylint instead or revert back to python 3.7.

What's the best way to revert to the previous python version on Termux?

The closest I can find to this error is this:

https://bugzilla.redhat.com/show_bug.cgi?id=1717653

[linusjf]

There's no fix on my Termux installation. Termux , like ArchLinux, has rolling updates. The only other alternative is to install a previous version via a build script. Do you have instructions for how to install a previous version of Python?

[ghost]

I did pip install pylint in a clear Termux installation and it works. Python version is the latest, v3.8.0.

Suggesting to reinstall python modules with apt purge python && apt install python (not just apt install --reinstall) and rm -rf ~/.cache before.

Python & modules versions:

[linusjf]

That worked. Thank you very much. I tried a reinstallation earlier. That didn't . I still have the same problem with Arch Linux on Termux, however. I'll try doing something similar with it as well.

[linusjf]

I reinstalled python on Arch Linux but I had to delete all the packages from /usr/lib/python3.8 for it to take effect. Pylint works just fine now.

[linusjf]

On installing prospector via pip , I was able to reproduce the error importing the modules once more.

[linusjf]

I receive the following error when installing pylint after installing prospector:

ERROR: prospector 1.1.7 has requirement astroid==2.2.5, but you'll have astroid 2.3.3 which is incompatible. ERROR: prospector 1.1.7 has requirement pylint==2.3.1, but you'll have pylint 2.4.4 which is incompatible.

I then have DistributionNotFound errors while running prospector.

[linusjf]

Kindly reopen the issue this time for Prospector.

[Grimler91]

@Fernal73 those error messages are pretty clear, you need to install older versions of astroid and pylint. It has nothing to do with termux

[linusjf]

Thanks, I'd rather wait for a later version of prospector. Yeah, I wasn't sure about that. There's some time lag before packages are available on Termux. I've posted to the pylint issue as well.

[Grimler91]

Prospector, astroid and pylint are python packages that you install through pip. We don't package or update those, we only deal with the packages that are installable through apt/pkg

[linusjf]

Ok. I wasn't aware of that. When I referred to delayed packages, I was referring to clang 10 not yet available on Termux. I was considering making a package request but I'm not coding in C++ at the moment and might not be able to provide a good enough reason for the Termux maintainers. I use clang-format as a secondary formatter for java source. That's where I'm coming from.

[Grimler91]

Clang 10 has not been released, in which distro have you been using it?

Only way getting it would be to build from git master, and we don't want to rebuild a package on each new commit so we stick to the official releases (or possibly release candidates)

[linusjf]

I'm not using Clang 10 but I always find the Clang 10 documentation first when I search online. I'm using whatever's available on Termux and Arch Linux on Termux. I have no interest in building anything on Termux.

[linusjf]

I've closed the other two issues.

pip install prospector==1.2.0.dev3

Is the solution for now.
