How to force virtualenv to install latest setuptools and pip from pypi?
Solution 1
It's not supported for security reasons.
Using virtualenv.py as an isolated script (i.e. without an associated virtualenv_support directory) is no longer supported for security reasons and will fail with an error. Along with this, --never-download is now always pinned to True, and is only being maintained in the short term for backward compatibility (Pull #412).
I can't use the --extra-search-dir
option either because it's currently broken https://github.com/pypa/virtualenv/issues/327
Looks like the only option is to simply wait for the virtualenv maintainers to update the bundled packages?
Solution 2
You can upgrade pip after installing your virtualenv by using pip install -U pip
.
I'm sure you could write a bootstrap-script to automate this step.
Solution 3
I needed the latest setuptools library, and the --extra-search-dir
flag wasn't working for me (even though it's been fixed apparently).
However, making a virtualenv without setuptools and then installing directly from PyPi worked great.
E.g. to set up a virtualenv called test
:
virtualenv --no-setuptools test
source test/bin/activate
wget https://bootstrap.pypa.io/ez_setup.py -O - | python
easy_install pip
Testing with
python -c 'import setuptools; print setuptools.__version__'
shows the right version.
Solution 4
I ran into the same problem, and I fixed it by upgrading setuptools
.
If env
is your virtual env, run the following:
$ env/bin/pip install --upgrade setuptools

Is it possible to force virtualenv to use the latest setuptools and pip available from pypi? Essentially, I'm looking for the opposite of the
--never-download
flag.Currently, when I make a new virtualenv, it uses the local (old) versions that come bundled with virtualenv.
$ v.mk testvenv New python executable in testvenv/bin/python Installing setuptools............done. Installing pip...............done. $ pip show setuptools --- Name: setuptools Version: 0.6c11 Location: /Users/cwilson/.virtualenvs/testvenv/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg Requires: $ pip search setuptools [...] setuptools - Easily download, build, install, upgrade, and uninstall Python packages INSTALLED: 0.6c11 LATEST: 0.7.2 [...]
