This page describes the requirements and procedure to be followed to install the RepEx package.

Note

Pre-requisites.The following are the minimal requirements to install the RepEx package.

  • python >= 2.7
  • virtualenv >= 1.11

The easiest way to install RepEx is to create virtualenv. This way, RepEx and its dependencies can easily be installed in user-space without clashing with potentially incompatible system-wide packages.

Tip

If the virtualenv command is not available, try the following set of commands:

wget --no-check-certificate https://pypi.python.org/packages/source/v/virtualenv/virtualenv-1.11.tar.gz
tar xzf virtualenv-1.11.tar.gz
python virtualenv-1.11/virtualenv.py --system-site-packages $HOME/repex-env/
source $HOME/repex-env/bin/activate

Step 1 : Create and activate virtualenv:

virtualenv $HOME/repex-env/

source $HOME/repex-env/bin/activate

Step 2 : Install RepEx:

pip install radical.repex

If installation was successful, you should be able to print the installed version of RepEx:

repex-version

Installation is complete!
