I am struggling to setup pymunk on my Ubuntu 16.04. I am using virtualenv, I have Python 3.5.2, pymunk 5.3.0 and cffi 1.11.0 installed.
I tried a very simple code first; basically, I created an empty Space and called step on it and everything worked smoothly. However, when I try to visualize it and create DrawOptions instance, I get strange errors, which I can't decipher. Also, I tried matplotlib_util and pygame_util, but both failed to create DrawOptions.
This is the code snippet I used:
import pymunk
import pyglet
import pymunk.pyglet_util
s = pymunk.Space()
options = pymunk.pyglet_util.DrawOptions()
s.debug_draw(options)
# s.step(0.02)
This is the output I get:

What do you think is causing that? Is that the python version I use, or maybe cffi compilation is faulty?
This error happens because there was a new version of pycparser (which is used by cffi) released, and that version breaks pymunk 5.3.0 and earlier versions. Yesterday I made a new release of Pymunk, 5.3.1 with a workaround for the problem. If you try to update your Pymunk version to 5.3.1 it should work.

It fails using pylint version 2.9.0 and 2.9.3. With version 2.8.3 it still works though.

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.

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'm new to django and using the anaconda cloud environment. Its been working well for 3 months plus but as of 7-24-2018 it is just stop to launch the navigator or open through cmd. I can't manage environments or install packages. Using the anaconda prompt also gives me the same error upon launching. It started when I wanted to install django-Oscar, but not having its dependencies I was forced to install the packages manually which in turn needed cytoolz that needs Microsoft Visual C++ build tools which I got to install as well but the error persists. Please help me!

I've just found out that I cant even use any conda commands except the : >conda --version< command only.
Please help me resolve this issue without uninstalling then reinstalling anaconda completely
Sorry to waste your time, I solved it by reinstalling anaconda completely and every project started working again....thanks to those who read it, the effort is appreciated.
It usually happen when you directly download and insall anaconda normally form its website.
Updating anaconda solved this issue for me in Manjaro and will surely work on Windows as well.
use conda update anaconda-navigator command to Update Anaconda.
If it doesn't starts, restart your pc and try to open it again.
I am trying to get pyttsx3 up and running on my computer. I did pip install pyttsx3 and pip install pypiwin32 I can see both of them in my python directory.
I type this code in to test it:
import pyttsx3
engine = pyttsx3.init()
engine.say("I will speak this text")
engine.runAndWait()
This is what comes out:
Traceback (most recent call last):
File "C:\Users\Danny\AppData\Local\Programs\Python\Python36\lib\site-packages\pyttsx3__init__.py", line 44, in init
eng = _activeEngines[driverName]

During handling of the above exception, another exception occurred:

I tried the same thing on another computer that already had both installed, and got the same output. Any idea what is going on with the win32com? I have no experience with it and am pretty lost. Thanks.
Ok, so I found the answer looking at other problems that were related to the win32com module. Basically what you need to do is navigate to your python scripts folder (in my case: C:\Users\Danny\AppData\Local\Programs\Python\Python36\Scripts) and run pywin32_postinstall. Upon running that script, it works perfectly!
Cheers!
Trying to run the most basic test of add.delay(1,2) using celery 4.1.0 with Python 3.6.4 and getting the following error:

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.
