2. Installing semver¶
2.1. Release Policy¶
As semver uses Semantic Versioning, breaking changes are only introduced in major
releases (incremented X
in “X.Y.Z”).
Refer to section Version Policy for a general overview.
For users who want or need to stay with major 3 releases only, add the
following version restriction (setup.py
, requirements.txt
,
or pyproject.toml
):
semver>=3,<4
This line avoids surprises. You will get any updates within the major 3 release like 3.1.x and above. However, you will never get an update for semver 4.0.0.
For users who have to stay with major 2 releases only, use the following line:
semver>=2,<3
2.2. Pip¶
pip3 install semver
If you want to install this specific version (for example, 3.0.0), use the command pip with an URL and its version:
pip3 install git+https://github.com/python-semver/python-semver.git@3.0.0
2.3. Linux Distributions¶
Note
Some Linux distributions can have outdated packages. These outdated packages does not contain the latest bug fixes or new features. If you need a newer package, you have these option:
