I have installed robotframework and robotframework-ride using pip. All the other required components are also updated. I am using Python 3.7.6 and Windows 10.
When I run RIDE, I get the following error:

I can't deduce whether I am doing something wrong. I have installed RIDE previously on this PC and others as well and this is the first time I am running into this error.
Kindly help.
To use newest wxPython version 4.1.0, you will have to install the current development version of RIDE (2.0b1.dev1) from source code, Otherwise, you should install version 4.0.7.post2.

It fails using pylint version 2.9.0 and 2.9.3. With version 2.8.3 it still works though.
See GitHub-issue under the provided link.

EDIT on different attempts producing the same error:
Installing pylint=2.9.3
Installing astroid and pylint (latest versions, no version specification)
Installing astroid and pylint and upgrade astroid to latest version during build-process (in AWS test-buildspec.yml) via pip install --upgrade astroid (suggested here)
It look like you found a bug/crash in pylint 2.9, you can open an issue here. You can downgrade to 2.8.3 while it's being fixed.
Thanks to the work of #Pierre.Sassoulas this issue has been resolved (see here).
After having proven that the following combination of pylint - and astroid - versions worked well together without producing the OP-error, new commits have been made to the GitHub-project to fix the problem:
pip install pylint==2.9.3
pip install git+git://github.com/PyCQA/astroid.git#c37b6fd47b62486fd6cbe77b913b568b809f1a6d#egg=astroid
From here going forward, the issue should not occur again installing the latest version of pylint combined with astroid. Yet, if the issue returns, I'll let you know here.
When compile chromium, I get the following error messages:

I was not sure if it's related to the version of jinja2.
And mine is v2.8 for sure.
autoninja -C out/Default is OK with me.
This question appears when I try to compile CrOS on my Ubuntu 16.04.
And autoninja -C out/Cros chrome is also fine. #_#
Find the reason!
It was because that ninja used jinja2 in the system instead of the version under src/third_party dir.
I solved this problem by uninstalling system jinja2.
Thanks for the guidance of tikuta#chromium.org. \o/

Is there any ideas how I can avoid it?
Looks like cryptoconditions library is doing it wrong.
You should file a bug asking to update required version of base58 and review all the calls to it. Usual behavior for Python3 is to return bytes on some_encoder_library.encode() and str on some_encoder_library.decode(). New versions of base58 module follow this rule although base58-encoded objects never contain any special symbols of course. cryptoconditions are still using previous version where b58encode were returning str.
Meanwhile you can make local modifications to the installed library or for it and install your fork instead.
It is likely that everything will work OK with encode() call removed from this line.

I cannot find any previous evidence of anyone hitting this error. I noticed from the celery site that only python 3.5 is mentioned as supported, is that the issue or is this something I am missing?
Any help would be much appreciated!
UPDATE: Tried with Python 3.5.5 and the problem persists. Tried with Django 4.0.2 and the problem persists.
UPDATE: Uninstalled librabbitmq and the problem stopped. This was seen after migration from Python 2.7.5, Django 1.7.7 to Python 3.6.4, Django 2.0.2.
After uninstalling librabbitmq, the problem was resolved.
I am running a code to connect Keithley multimeter to my laptop. I am using windows 10 and python 2.7. But when I try to run the code, this appears. Help me, i am very basic in programming and computer and I am in need of help. I have been searching for solution for days but to no avail , after I have fixed one error, another error pops up. this is the latest error. I hope after this one is solved i can use it .
