How to Update Requirements Files¶

The different requirements files introduced in Software Process section are the following:

requirements.txt¶

requirements.txt of the project can be created or updated and then captured using the following script:

mkvirtualenv hdmf-requirements

cd hdmf
pip install .
pip check # check for package conflicts
pip freeze > requirements.txt

deactivate
rmvirtualenv hdmf-requirements

requirements-(dev|doc|opt).txt¶

Any of these requirements files can be updated using the following scripts:

cd hdmf

# Set the requirements file to update
target_requirements=requirements-dev.txt

mkvirtualenv hdmf-requirements

# Install updated requirements
pip install -U -r $target_requirements

# If relevant, you could pip install new requirements now
# pip install -U <name-of-new-requirement>

# Check for any conflicts in installed packages
pip check

# Update list of pinned requirements
pip freeze > $target_requirements

deactivate
rmvirtualenv hdmf-requirements

requirements-min.txt¶

Minimum requirements should be updated manually if a new feature or bug fix is added in a dependency that is required for proper running of HDMF. Minimum requirements should also be updated if a user requests that HDMF be installable with an older version of a dependency, all tests pass using the older version, and there is no valid reason for the minimum version to be as high as it is.
