I decided to give pelican a try, but when I run pelican-quickstart, I get the following dialog:
$ pelican-quickstart
Traceback (most recent call last):

There was a similar error message in this post, and since I'm running Python 2.7.6 on OS X 10.10 (Yosemite), there may be a similar issue.
What's the best way to address this?
Reinstall Pelican doesn't help me, so I made a little fix in pelican
Modifications were made in following file
/Library/Python/2.7/site-packages/pelican/readers.py
at line 24 place
from six.moves import html_parser
instead of
from six.moves.html_parser import HTMLParser
and at line 299
class _HTMLParser(html_parser.HTMLParser):
instead of
class _HTMLParser(HTMLParser):
Modification actual for pelican 3.6.0, but seems to applicable for other version if search for this lines in readers.py file. This is just quick workaround, hope this problem will be solved at pelican's side.
This error seems to come from Python 2.7.6 on OSX. When I install python via Homebrew and reinstall this module I got rid of this error.
$ pip uninstall pelican
$ brew install python
$ which python # should show /usr/local/bin/python
$ python -V # should show Python 2.7.8
$ pip install pelican
I think that you've probably encountered with version conflict problem in module six.
Try sudo pip install virtualenv to create an isolate python environment.
start
create your pelican path mkdir /path/to/pelican
go to /path/to/pelican and create an isolate python environment with virtualenv venv
activate virtualenv source venv/bin/activate
install pelican under the venv(without sudo!) pip install pelican markdown
done
and now you are free to any problem mentioned above. all the dependencies in the venv are isolated from the global environment.
To quit the venv, type deactivate
I was running into the same error message.
six was also already installed, but an old version (1.4.1)
pip install six --upgrade
Installed six 1.10.0, which made pelican-quickstart finally work :)
You may need to install six.
if you're using pip, try
pip install six
and then restart pelican-quickstart

ImportError: cannot import name 'IncompleteRead'
On Ubuntu 15.10; tried removing python 3 completely and reinstalling, still having issues. Help?
Edit: UPDATE: Tried using my bootable USB to repair Ubuntu and get back to original config and reinstalled via sudo apt-get install python3-pip, but now it generates a crash report saying:
Sorry, the application pip3 has unexpectedly crashed.
This seems to be an issue with pip's interaction with the requests package. requests dropped the IncompleteRead module but older versions of pip, which you have, still rely on it, newer versions don't.
You should try updating pip via easy_install-3.5 (if you have Python 3.5) or easy_install-3 for other versions:
sudo easy_install-3.5 -U pip
or:
sudo easy_install-3 -U pip
and you should be good to go.
Had similar error on Raspberry Pi. The solution was a combination of all proposals above:
sudo pip install --upgrade pip
sudo pip install --upgrade requests
sudo easy_install3 -U pip
It happened me when I tried to install a pip module to my Python3 installation. I mistakenly run pip instead of pip3 and it installed Python2 modules into Python3 installation. After that I realized command was wrong, I run pip3 this time. But, it was no good, installation was blown up, there were errors in Python2 like parenthesis missing in print statement(obviously this is an error for Python3). Eventually, it blown up my terminal too, I needed to install another terminal.
Like you did, I tried to install and reinstall everything, but it didn't work. Fix needed to be done manually. After trying several days and failing, I backed up my files and reinstalled Ubuntu.
I know this is not what you want, but maybe you can save your time by accepting that reinstalling the OS is the easiest solution.
Make sure you install newest versions of pip and requests:
pip install --upgrade pip
pip install --upgrade requests
Tonight I am trying to get the package called "requests" installed and have begun fumbling around with the terminal and do not have very much intuition when it comes to this sort of thing.
Computer is a mac mini, osx version 10.9.4
In /Library/Python I have 4 folders: 2.3 2.5 2.6 and 2.7.
In /Applications I have "Python 2.7" and "Python 3.4"
I can open IDLE and type 8+8 and I get 16 just fine.
Here is the error I am getting in terminal:
host-210-117:~ Mario$ python
ImportError: No module named site
host-210-117:~ Mario$ pip
ImportError: No module named site
My goal is to run this command in the terminal:
pip install requests
I believe pip is already installed. I run the file "get-pip.py" in IDLE and this is what it says:
Requirement already up-to-date: pip in /Library/Python/2.7/site-packages/pip-1.5.6-py2.7.egg
Cleaning up...
This may have something to do with paths? I would appreciate some guidance/hints/tips, thanks!
Oh and just a little more info that might help solve this question. Here is the first few lines of the program I'm running:
import base64
import hmac
import json
import requests
import time
import urllib
import os
Which gives me this error in IDLE (so I guess it importing those first few packages with no problem?) :

From what I can tell you have three versions of Python on your system.
The one that comes with OSX /Library/Frameworks/Python.framework/Versions/2.7/
Python 2.7 from python.org /Library/Python/2.7/site-packages
Python 3.4 from python.org
pip is installed against the Python 2.7 version you downloaded (the one you see in your Applications folder), unfortunately the default Python for your shell is the one that's bundled with OSX, and there is no pip installed there.
IDLE is also bundled with the Python that you downloaded, which is why it keeps telling you that pip is installed, but it doesn't work from the shell.
Since you are probably using the Python downloaded from python.org as your "primary" Python (after all, its the one with IDLE that you are using), you need to set your shell environment to point to this Python as default.
The easiest way to do that is to add a variable in .bashrc that creates an alias python and points it to the right binary. To do that, add this line to /Users/yourusername/.bashrc - files with . are hidden by default, so you'll have to write the entire file name in the command line to open it. Add the following line:
alias python=/Library/Python/2.7/python
Save the file and then close all terminal windows and open it again. Now type pip and it should work correctly, and then you can proceed to installing requests.
For future reference, try to stick with one version of Python. I personally ignore the bundled version and use the one from brew, but you can stick to the Python downloaded from python.org.
I fixed mine with:
brew reinstall python
It fixed all my broken paths. I think I broke it with a broken brew package that had a wrong python version dependancy or something like that.
site.py is a standard module that is run by python by default. It allows tweaking sys.path and running some code before your code starts running. It should live in the standard library and can hardly be somehow absent. However, you can disable automatic importing of the module by passing -S switch to python.
Anyway, you should somehow inspect why the module can not be imported. Try to examine sys.path list.
You are trying to install the package in '/Library/Python/2.7/site-packages/requests' but it requires root permissions to do so. This should do the trick:
$ sudo pip install requests
I did some reading. The command line,
python3.10 -m pip install pandas
as long as you have the latest version of pip updated, this will install pandas to the specific python that you wanted otherwise it defaults to the latest version installed in my case Anaconda. You can change the python3.10 for your desired version of python to install too.
sudo easy_install pip
sudo pip install requests
I have six installed (even reinstalled it).

This is on CentOS.
Uninstalling and reinstalling six using pip didn't work
sudo pip uninstall six
sudo pip install six
However, I was able to solve the problem using easy_install:
easy_install --upgrade six
Reason for this is when you install Six using PIP the location of the Six library isnt added to Pythons Path so when trying to use the commands, python cant find them. Installing with Easy_Install doesn't have this problem, when it is installing six it automatically updates the python path variable so python can find the library.
Installing by Easy_Install as answered before resolves this but you can alternatively add the location to the python path variable.
I came across the same problem today, reinstalling with pip did not work and i can not do it with easy_install as it a custom package
the solution was to point the PYTHONPATH variable to the site-packages that contains the package
export PYTHONPATH=$PYTHONPATH:/path/to/sites-package
you will face this problem if you work with virtual env
I'm completely new to programming. I've been trying various ways to install NLTK on my Mac (running OS 10.5.8), and none of them is working. Please help! Here's what I've done so far.
Since at first I didn't realize that newer versions of Python required OS 10.6 or higher, I first tried to install the latest versions of both Python 3 and Python 2, but this obviously didn't work. I then cottoned on and found an older installation (the filename is python-2.7.6-macosx10.3.dmg), which installed successfully.
I then tried to follow the instructions on this page, which I copy below:
Install Setuptools: http://pypi.python.org/pypi/setuptools
Install Pip: run sudo easy_install pip
Install Numpy (optional): run sudo pip install -U numpy
Install PyYAML and NLTK: run sudo pip install -U pyyaml nltk
Test installation: run python then type import nltk
Steps 1 and 2 worked fine, but when I try steps 3 and 4, I get an error. The error is the same whether I try step 3 or step 4:
unknown0021E9E0E476:~ Tom$ sudo pip install -U numpy

I then found a different set of instructions on this page. It first has you install Xcode and MacPorts, which I did (again finding older versions compatible with 10.5.8). I got through the next few steps successfully: installed python27, made it the system default (sudo port select --set python python27), and installed the dependencies py27-numpy, py27-yaml, and py27-scipy. However, I can't install one needed package, py27-matplotlib. Here's what happens when I try:

Without this package, I can't go on to install NLTK.
I've also tried installing NLTK in PyCharm, but that didn't work either: see this question. I'm at my wits' end here, so any help would be much appreciated!
ETA: Problem solved! I downloaded the tar.gz file from https://pypi.python.org/pypi/nltk and followed the install instructions in the package, and now I can import NLTK in the Python shell. Is it possible that I was simply trying to install things while in the wrong directory? (I'd still like to use NLTK in PyCharm, so answers to that question will still be welcome.)
Try installing the scipy package which includes matplotlib and numpy, I was a TA on a course where we used numpy and matplotlib quite a lot and using the scipy package to install was a solution for a lot of people.
The individual binary and source packages are available from: scipy docs
sudo port install py27-numpy py27-scipy py27-matplotlib py27-ipython +notebook py27-pandas py27-sympy py27-nose
I installed virtualenv using pip and now receive the following error whenever I actually try and use it:

Similarly, I installed django with pip, and when I try and import django in python I get: ImportError: No module named django.
I tried to install virtualenv again, this time using easy_install instead of pip. easy_install gave me an error saying that it was having issues with my PYTHONPATH environment variable. Lo and behold, after reading http://www.stereoplex.com/blog/understanding-imports-and-pythonpath, PYTHONPATH is what python uses to find modules, and my PYTHONPATH was unset.
After setting PYTHONPATH to /lib/python3.3/site-packages (where pip was installing my modules), both virtualenv and importing django functioned properly.
Note: because I have both python2.7 and python 3.3 installed, for me pip actually installs packages to /lib/python2.7/site-packages while pip3 installs packages to the aforementioned /lib/python3.3/site-packages.
