I want to learn django so I tried to create a virtual env and I am getting this error:
mkvirtualenv django
Traceback (most recent call last):

I haven't used python in a while so i'm not sure what the issue is:
virtualenv --version

You're using mkvirtualenv which is a virtualenvwrapper command. You probably do not have virtualenvwrapper installed.
Type virtualenvwrapper in your command line and observe the input. If you get something like command not found, then you should install it first.
You should install it with pip like so pip install virtualenvwrapper.
There are some post-installation steps, the most important one being source /usr/local/bin/virtualenvwrapper.sh that makes commands like mkvirtualenv, rmvirtualenv available.
See virtualenvwrapper's documentation.
Alternatively, you can also just make use of virtualenv. Check that you have it installed like so
virtualenv --version
If you do not, you can install it with pip. Once you have it installed, you can create your virtualenv like so
virtualenv <name> in the directory of your choice.

Using OSX El Capitan. Just installed a bunch of pip module and was following a few online tutorials, must have broken something as now I get the following error whenever I try to use pip (although python seems to run fine).
$ pip install pandas

Any helping fixing would be much appreciated.
Thanks.
Reinstall using easy_install. Close the terminal and reopen. Pip should now work.
Try updating pip first by typing pip install -U pip and the try pip install pandas. I myself use Anaconda/Miniconda. Most of the packages are well handled and the dependencies are taken care of as well by the conda package manager.
I am running python based software that requires a virtualenv with various additional python packages installed therein. Here are the install instructions:
Clone the repository to a shared filesysem on a cluster
>git clone https://github.com/jgurtowski/nanocorr
>cd nanocorr
Create a virtual environment to install python dependencies
>virtualenv nanocorr_ve
>source nanocorr_ve/bin/activate
install the following packages using pip:
pip install git+https://github.com/cython/cython
pip install numpy
pip install h5py
pip install git+https://github.com/jgurtowski/pbcore_python
pip install git+https://github.com/jgurtowski/pbdagcon_python
pip install git+https://github.com/jgurtowski/jbio
pip install git+https://github.com/jgurtowski/jptools
#Finally install the nanocorr package itself
> python setup.py install
I achieved this with no problems. However, While running the software, I found that it was failing with the following traceback.

I have found details as to the specific error itself, but I think the source of the problem is that the traceback clearly shows a transition from modules being imported from the /local virtualenv site-packages to another site-packages directory in /programs.
My question is the following: Given that I have the same python packages installed in two separate places, 1 in the system wide location and one in virtualenv, how do I ensure that other programs properly import all modules from within the same virtualenv sit-packages directory. I thought this would have been done automatically. I am not 100% sure that this is the sole reason for the error, but being able to fix this would help me to further debug.
It depends on how you set up your env. virtualenv has a flag option that forces it to not use the system site packages
virtualenv --no-site-packages my_env
It is the default behavior for recent versions (>=1.7).
If you've defined a PYTHONPATH environment variable, that will affect your virtualenv environment as well.
I updated setuptools using:
easy_install -U setuptool
This ran fine. I then realized I did not want to use the most recent version of setuptools and deleted setuptools-18.3.2-py2.6.egg file from /usr/lib/python2.6/site-packages. After I did this I am getting the following errors when trying to install anything using easy_install shown below.
easy_install ReviewBoard-1.7.6-py2.6
Traceback (most recent call last):
File "/usr/bin/easy_install", line 5, in <module>
from pkg_resources import load_entry_point

File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 546, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: setuptools>=0.7
Looks like ReviewBoard needs setuptools as a dependency. When you ran easy_install ReviewBoard-1.7.6-py2.6, it would have detected that this dependency is already installed but actually it wasn't.
One reason could be that deleting the .egg file was not the complete process of getting rid of a package installed with easy_install. You also need to remove the corresponding line from site-packages/easy-install.pth. Refer: https://stackoverflow.com/a/1233282/4045754
I'm trying to use the virtualenvwrapper to make a python 3 based virtualenv. However,I'm when I pass the optional interpreter argument, I'm seeing this error. I'm running Ubuntu 15.04. I tried reinstalling virtualenv and virtualenvwrapper without success. Thanks for all your help!

I come across same issue, but after I downgrade virtualenv to 12.0.2, this problem disappears.
This is sort of a workaround for now.
Create a virtualenv using pyvenv.
# install pyvenv on Ubuntu
sudo apt-get install python3-venv
To minimize disruption in your normal workflow, pass a destination directory that is the same as the one used by virtualenvwrapper Like so,
pyvenv example ~/.virtualenvs/example
This is automatically working with workon and cdproject commands. I don't use much else that is provided by virtualenvwrapper
Hope this helps.
You can upgrade to the most recent version of virtualenv, with:
sudo pip install --upgrade https://github.com/pypa/virtualenv/archive/master.zip
virtualenv --version
# Returns 15.2.0.dev0 when I ran it
The following command then works:
mkvirtualenv scriptcutter --python=/usr/bin/python3
Apparently, the develop branch was dropped, so the URL with "develop" will no longer work. My answer was based off of #pjotr_dolphin's comment, with the URL updated.
I have a rhel machine with python2.6 installed on it. I've been trying to have an alternate install of python2.7 and set up a virtualenv for using 2.7. I installed python2.7 by building from source as follows:
./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make && make altinstall
I already had virtualenv installed on the system so I used it to create a venv for 2.7 as follows:
virtualenv -p python2.7 --no-setuptools py27
. py27/bin/activate
Now when I try to install pip inside the venv, it fails like so:
python get-pip.py
Traceback (most recent call last):

I've installed python 2.7.8.

I was in a situation similar to yours, and I eventually found the fix. At least in my case the root problem was that when I compiled python 2.7.8 the build process didn't find the proper OpenSSL libraries (because they were not installed on my system). After make finished running it showed a summary similar to this:
Failed to find the necessary bits to build these modules:
_bsddb _curses _curses_panel
_hashlib _sqlite3 _ssl
This doesn't prevent make install from working, and after that Python works just fine, except that it can't access https URLs and other related functionality. You can tell if this is your case by starting python and then typing
import ssl
If you see an ImportError, then the ssl module is missing. Otherwise, you see no message at all.
I fixed this by installing the OpenSSL libraries by running (as root):
yum install openssl-devel
After this was in place, I rebuilt Python with make (now _ssl was not listed as missing), followed by make install. After this, running get-pip.py worked without a hitch.
Hope this helps!
