install_extras¶

ExtrasCommand.install_extras()[source]¶

Installs extras requirements using python -m pip install -U -r requirements.txt

The python executable is determined using sys.executable, and the requirements.txt file is generated into a temporary file which is deleted after the install is finished.

If the argument --extra / -e ( extra ) is passed, then this will install only the requirements for that extra.

Example (assuming this class is registered as extras)

# Install ALL extras requirements
./setup.py extras --install

# Install only the requirements for the extra 'cache'
./setup.py extras --install --extra=cache
# Shorthand version (YMMV based on setuptools/distutils version)
./setup.py extras -i -e cache
