Use virtualenv in production without python-dev

Question

I have a python web project and I use virtualenv with pip on my dev server. Some python packages require compilation, so I should have python-dev in order to pip install them. Is there a way to reproduce my requirements stack in production keeping virtualenv, but no python-dev, as I am dealing with no dev server ?

Answer 1

pip 1.4 added support for installing and building wheel package.

"Wheel" is a built, archive format that can greatly speed installation compared to building and installing from source archives.

procedure

1. Install/upgrade to pip 1.4. (one time only)

2. Install wheel in both dev, production server. (one time only)

   pip install wheel
   

3. Build wheel package in dev server:

   pip wheel --wheel-dir=/local/wheels -r requirements.txt
   

4. Transfer /local/wheels packages to production server.

5. Install packages in production server:

   pip install --use-wheel --no-index --find-links=/local/wheels -r requirements.txt
   

Reference

See pip documentation about building and installing wheels for more detail.
