I tried to install pygments-ipython-console.
In requirements it says:
This needs IPython 1.0+ for sphinxext module
How can I install this module?
I dont find anything in my packet manager (yum).
The following error indicates that the module is not installed:
An error occurred in an add-on.

Thanks to pokoli I realized that my version was not recent enough.
In the README of pygments-ipython-console it still says version 1.0+ is required, that's a mistake.
I have now updated to version 2.2 but still got an Error:
ImportError: cannot import name IPythonConsoleLexer.
That is because there was a renaming in IPython. There is a fork in the pygments-ipython-console repository where this is fixed. So I had to clone the forked repository instead of the initial one.
I reinstalled according to the readme and now everything works fine.

I'm currently following the Scrapy tutorial and am at the step where there's a creation of a project, however this error is produced everytime I run the command scrapy startproject tutorial.

I suspected that the issue is in my installation of Scrapy, so I tried reinstalling Scrapy(first via pip then conda) but it still doesn't fix the problem. I then tried to install the packages that Scrapy needed(one by one) but it's still not fixing anything.
How do I go about fixing this?
Can you try to install Win64OpenSSL_Light-1_0_2h and reinstall cryptography?
pip install -I cryptography

I'm using terminal on mac, and anytime I attempt to use pip, I get the following error message telling me that it cannot find a module named zlib:
$ pip --version

ModuleNotFoundError: No module named 'zlib'
I've read several SO posts with the same error message, and have tried their solutions, including attempting to install zlib using homebrew, which fails, and updating my Xcode developer tools. I also installed pip earlier using python get-pip.py, and it said it installed successfully.
The reason I need pip is to install a package for use on python 2.7, but doing $ pip install "package-name" produces the same error as above. I have both Python 2 and 3 installed on my machine, if that helps. I'm kind of new to pip and using the command line in general, and I'm super confused; if anyone could help me out I'd really appreciate it.
This is the OP. I was able to fix the issue, and wanted to post my solution here in case it would help others.
Essentially I believe it occurred because Python2 is default on my machine, but pip is by default pointing to resources pertaining to Python3, or something like that. Doing pip2 --version instead provided the expected response.
I'm a beginner in OpenGL/OpenCL.
I'm trying to execute code from this

As I understand, WGL is an API for Windows OS and not for Linux. Should I somehow specify my platform before? Or how can I fix this?
Thanks in advance!
The code you are using (PyOpenGL 2014.1) is importing two platform-specific modules (WGL and GLX). PyOpenGL should have raised that error as an ImportError (rather than the AttributeError), but it still would have failed.
PyOpenCL has, in the meantime, worked around the issue in their github repository. If you have git installed (and pip) then this should get you a new version (note: not set up for OpenCL development here, so can't actually test this):
pip install git+https://github.com/pyopencl/pyopencl#egg=pyopencl
I installed twill by using pip, and another try using easy_install, I want to play around with it in Powershell. Following this page - http://twill.idyll.org/ I wanted to play around with it.
To start using twill, install it and then type twill-sh. At the prompt type:
go http://www.slashdot.org/
show
showforms
showhistory
When I type twill-sh it doesn't work. I have typed it in power shell, tried it after loading python, and tried it after using import twill and trying it. I only get errors.
Traceback (most recent call last):

How do I just load modules so I can play with them without writing scripts?
I had the same problem. Further down the log I found the following:
File "C:\Anaconda\lib\site-packages\lxml\cssselect.py", line 18, in <module> raise ImportError('cssselect seems not to be installed. '
ImportError: cssselect seems not to be installed. See http://packages.python.org/cssselect/
Which I fixed by installing package cssselect (using conda as I have an Anaconda installation, pip should do the same).
conda install cssselect
I am completely newbie to Python and just trying to install Dynamic-DynamoDB python package on RHEL5 Linux for very first time. I didn't have pip on my system so I followed instructions as in asnwer to What is the official "preferred" way to install pip and virtualenv systemwide?
Now when I try to install dynamic-dynamoDB as mentioned in installing instructions, it gives me error.
pip install dynamic-dynamodb

Any suggestions on what am I missing here?
I'm the author of Dynamic-DynamoDB. Sorry for a late answer, I wanted to answer anyway in case anyone else has the same problem later on.
The reason is that the Python version is too old. Dynamic DynamoDB supports Python >2.6.
