I have tried to run pip install --upgrade setuptools and sudo easy_install -U setuptools but neither works. How can I solve this problem?
wsgiref is already been included as a standard library in Python 3...
So in case if you are trying with Python 3 just go ahead and import wsgiref thats it.
According to this line SyntaxError: Missing parentheses in call to 'print', I think it needs Python 2.x to run the setup.py. Whether to use parentheses in print is the different syntax of Python 2 and Python 3.
This is the solution from the Github issue:
There are a few fixes that will get you running, in order of least work to most:
Switch over to python2.7 for your will installs.
Try to upgrade wsgiref with pip install --upgrade wsgiref, and see if the latest version works with your setup, and with will (if it doesn't, you'd notice the http/webhooks stuff not working.
If you try 2) and it works, submit a PR here with the upgraded version in requirements.txt. (You can find out what versions you've got by using pip freeze).
You can find more about the syntax difference here
Solution:
Flask-restful is deprecated, use version flask-restx

According to Django 2.0 release notes Django 2.0 onwards will only support python 3, making the 1.11.X the last release series to support python 2.
See quote from the release notes page:
Django 2.0 supports Python 3.4, 3.5, and 3.6. We highly recommend and only officially support the latest release of each series.
The Django 1.11.x series is the last to support Python 2.7.
However when running pip2 install Django, django version 2 is being installed (which then fails because it assumes functionality not available in python 2):

I know I can manually specify requirement version below 2, making pip install a version valid for python 2, however that will complicate the installation process if I want to support both python2 and python3, and would have assumed pip will know to install only versions compatible with the python it's running from.
My questions, therefore, as the following:
Why is pip attempting to install Django2 with python2 instead of automatically picking the last compatible version? Isn't that part of pips capabilities?
Is there a way to make a single requirements.txt that will install Django<2.0 when running from python2 and Django>=2.0 when running with python3?
Why is pip attempting to install Django2 with python2 instead of automatically picking the last compatible version? Isn't that part of pips capabilities?
As Alasdair pointed out in the comments already, this is a known bug in Django: bug #28878.
Is there a way to make a single requirements.txt that will install Django<2.0 when running from python2 and Django>=2.0 when running with python3?
You can use the environment markers (see PEP 508):
# requirements.txt
django>=1.11,<2.0; python_version<"3.4"
django>=2.0; python_version>="3.4"
This will install one and skip another django dependency, depending on what python you are using:
$ pip2.7 install -r requirements.txt
Ignoring django: markers 'python_version >= "3.4"' don't match your environment

I am new to Python and I am trying to install recsys package.
http://ocelma.net/software/python-recsys/build/html/installation.html
For this i need to install some pre-requiste packages, so i have to run this using pip
pip install csc-pysparse networkx divisi2
But whenever i run this i get the following in logs

I checked that setuptools exist in my python installation here
C:\Python34\lib\site-packages
I have ran everything from unstinalling setuptools to install it again, upgrade command, but it does not work.
Not able to figure out why setuptools is not found. Is it not found in the path of where pip resolves it from ?
cheers,
Saurav
The code triggering the error is Python 2-specific and is illegal in Python 3.
Apparently, csc-pysparse doesn't support Python 3 (its README only mentions 2.6) and looks abandoned (6 years since last commit).
Some guys out there suggest replacing it with SciPy.
The error is coming from the installation code of recsys package. In order to avoid this error, you need to install setuptools separately.
For debian machines, the below command will work.
sudo apt-get install python3-setuptools
For other machines, please checkout installation instructions at the link
Once setuptools package is installed, you can proceed with csc-pysparse installation.
So, I've been trying to install the gutenberg module for python pip install gutenberg using the directions at this site (using brew instead of pip since I'm on a mac). Every time I try do do it, it returns with this:

I tried doing easy_install, re-installing setup-tools, and a bunch of other stuff. Here's the links to all the things I've tried:
Can't install via pip because of egg_info error

When I say I've tried all of them, I really do mean all of the suggestions in the links above, so maybe I messed something up in that process. I'm not entirely sure what's going on, I've been working on it for hours and haven't been able to discover with any successful solutions. I'm not sure if I'm missing something here but if anyone has any suggestions it would really help.
Just an addition from my side...
I fixed this issue on my Windows 10 for python 3.4:
Go to Powershell Window and type below:
1) Update pip >>>>> py -3.4 -m pip install --upgrade pip
2) Install Numpy >>>>> py -3.4 -m pip install numpy
3) Install Matplotlib >>>> py -3.4 -m pip install matplotlib
I am trying to build a script that makes use of scikit-image on Travis-ci. It complains that six is not up to date. Just to be sure, I tried to replicate the .travis.yml of the scikit-image project on github, but it did nothing to change the situation. I also tried to update six, but to no avail...
Does someone know how to build scikit-image on travis?

You are using pip version 6.0.7, however version 6.0.8 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Your build has been stopped.
If you get an error that a specific dependency isn't being met, being more specific about that dependency usually helps. I like to put dependencies that I don't directly use in a before_install section.
before_install:
pip install six>=1.3
install:
pip install -r requirements.txt
pip allows you to specify constraints on the versions of packages you install. If you had to use 1.3 exactly you could use ==.
Trying to install oursql driver for python3x and sqlalchemy0.8 on ubuntu 12.10. It fails with the following error.

When I try to install cython I seem to already have it:
sudo pip-3.2 install cython
Requirement already satisfied (use --upgrade to upgrade): cython in /usr/local/lib/python3.2/dist-packages
Cleaning up.
What can I do to make it run?
Had the same error when running pip-3.2.
This is how I made it work:
Created my env using python-3.2:
virtualenv -p /usr/bin/python3.2
Installed the required packages:
sudo apt-get install python-dev
sudo apt-get install libmysqlclient-dev
Then installed:
sudo pip install cython
sudo pip install oursql
Edit1:
I was able to get pass you error with my above recomendations, but i was wrong (python3.2 was unable to read oursql). I tried the following and was able to make a connection:
First:
sudo apt-get install python3.2-dev
Then installed oursql for Python 3 from source (as suggested by it's maintainer here):
Get the Python 3 version of oursql from here and compile it from source (Don't have enough reputation to post the link, just go to oursql official site for installation instructions).
The maintainers have two packages, one for python 2.x and one for python 3.x, you should run:
pip install oursql3
There is nothing about cython.
You just encoutered a syntax error in print, because the print statement doesn't use brackets there. They were optional in Python 2's print statement, but are required in Python 3's print() function.
install it manually - reqs: python-dev, cython
then download oursql package (try 0.9.3.zip)
and
python setup.py install
