pip-update-requirements
Update the packages in a requirements.txt file.
Installation
pip install pur
Usage
Give pur your requirements.txt file and it updates all your packages to
the latest versions.
For example, given a requirements.txt file:
flask==0.9 sqlalchemy==0.9.10 alembic==0.8.4
Running pur on that file updates the packages to current latest versions:
$ pur -r requirements.txt Updated flask: 0.9 -> 1.0.2 Updated sqlalchemy: 0.9.10 -> 1.2.8 Updated alembic: 0.8.4 -> 0.9.9 All requirements up-to-date.
Pur never modifies your environment or installed packages, it only modifies
your requirements.txt file.
You can also use Pur directly from Python:
$ python
Python 3.6.1
>>> from pur import update_requirements
>>> print([x[0]['message'] for x in update_requirements(input_file='requirements.txt').values()])
['Updated flask: 0.9 -> 1.0.2', 'Updated sqlalchemy: 0.9.10 -> 1.2.8', 'Updated alembic: 0.8.4 -> 0.9.9']
>>> print(open('requirements.txt').read())
flask==1.0.2
sqlalchemy==1.2.8
alembic==0.9.9
