I am trying to set up a python environment on a remote computer via ssh (with no root access). I am following the instructions below:
Download the virtualenv script:
wget -O /tmp/virtualenv.py https://raw.github.com/pypa/virtualenv/master/virtualenv.py
Run the virtual env script
python /tmp/virtualenv.py $HOME/pyenv/
which will setup the environment in the "pyenv" directory in your $HOME space
Update the environment
If you are using bash (I hope you do), then you should add:
. $HOME/pyenv/bin/activate
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/ioa//lib:/usr/local/lib64
to your .bashrc
And when I run python /tmp/virtualenv.py $HOME/pyenv/, I am getting the error
New python executable in /home/lht26/pyenv/bin/python
Cannot find a wheel for setuptools

What should I do?
Here are the steps to run virtualenv.
First, install pip (pip3 if you have 3 version of python):
sudo apt-get install python-pip
Then run the following:
sudo pip install virtualenv
mkdir myproject
cd myproject
virtualenv venv
. venv/bin/activate

I recently upgraded python from 2.7.6 to 2.7.9 using homebrew. I then tried to 'revirtualise' an existing virtual environment:
sudo virtualenv -p python2.7 existingvenv
But am getting this error:

I also get the above error when running any pip install x inside the above active virtual environment.
I don't get the error when creating a new virtualenv:
$ virtualenv -p python2.7 newvenv
Running virtualenv with interpreter /Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7

Is there an old symlink or something inside the existing virtualenv causing the issue and how can I resolve this?
This is because of a new feature in Python, which wheel 0.24 is not compatible with. You'll find a folder called virtualenv_support containing base install files for setuptools, pip, and wheel under your Python 2.7 system install. There are a few solutions. The easiest is to just remove wheel-0.24* from the virtualenv_support folder. If you want to go a step farther, you could download version 0.26 of the wheel .whl file and replace it.
did you try:
sudo virtualenv --clear -p python2.7 existingvenv
?
I'm new to Python development and I'm trying to instal virtualenv in my project directory.

I installed pip with
easy_install pip
Then I installed virtualenv with
pip install virtualenv
Without any errors. However I'm still getting this. I didn't want to try it with sudo. Should I?
UPDATE: I installed them with sudo, and I got rid of this error. However another one when trying to install something with pip:
air:dashboard alexandrurada$ pip install flask
-bash: /usr/local/bin/pip: "path_here": bad interpreter: No such file or directory
UPDATE 2: The earlier error was because of a space inside a directory name. Looks like path doesn't work with such names.
Anyway, the error I'm getting now is
File "/usr/local/bin/pip", line 7, in <module>
from pip import main
ImportError: No module named pip
I checked my /usr/local/bin/pip and the file exists.
You need sudo pip install virtualenv to install virtualenv globally. When setting up your virtualenvs make sure you don't use sudo and that you activate your virtualenv before trying to install.
[Errno 13] Permission denied: means you don't have write permissions.
Install a newer version of pip and avoid using easy_install.
Download pip from: https://bootstrap.pypa.io/get-pip.py
and then run Python on it:
$ python get-pip.py
If you want to install pip to the global path, you likely want to run that last command with sudo. Without using sudo, pip will get installed for use with whatever Python interpreter is in your path.
From here, you can install virtualenv with pip:
$ pip install virtualenv
From your responses, it seems like you'd be best served by getting your system in a known state: Download that file, then run sudo python get-pip.py so you're running with a known-working pip install.

You have to install openssl first, than python. So openssl support will work (python compiles with ssl support if openssl is available at install time.).
In addition to Mathias' answer, you also need to make sure that the following environment variables are set before compiling python3:
LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include
I need virtualenv for Pyramid on XP.
pip installs fine and so does virtualenv
But when I try to create an instance directory, virtualenv bombs.
I uninstalled and re-installed virtualenv, but I keep getting the same problem.
Any ideas?

I am using Ubuntu 11.10 and Python 2.7.
EDIT:
Figured it out.
I originally installed it with pip, so I uninstalled via pip and that reinstalled via apt-get.
I had the same on debian. Upgrade python-virtualenv resolves the problem.
apt-get upgrade python-virtualenv
virtualenv looks to be trying to install pip using easy_install from a local archive. Can you verify that it exists at /usr/local/lib/pytho...pport/pip-1.1.tar.gz ?
You may want to ensure that you have pip properly install beforehand. Try: easy_install -U pip first.
In mac run pip install virtualenv virtualenvwrapper to install virtualenv.
You should make sure the path to easy_install does not have spaces in it: /home/zach/School/CS...env/bin/easy_install
If you are Debian user, then this command should resolve the problem:
sudo apt-get upgrade python-virtualenv
