Installing semver¶

Release Policy¶

As semver uses Semantic Versioning, breaking changes are only introduced in major releases (incremented X in “X.Y.Z”).

For users who want to stay with major 2 releases only, add the following version restriction:

semver>=2,<3

This line avoids surprises. You will get any updates within the major 2 release like 2.9.1, 2.10.0, or above. However, you will never get an update for semver 3.0.0.

Keep in mind, as this line avoids any major version updates, you also will never get new exciting features or bug fixes.

You can add this line in your file setup.py, requirements.txt, or any other file that lists your dependencies.

Pip¶

For Python 2:

pip install semver

For Python 3:

pip3 install semver

If you want to install this specific version (for example, 2.10.0), use the command pip with an URL and its version:

pip3 install git+https://github.com/python-semver/python-semver.git@2.10.0

Some Linux distributions can have outdated packages. These outdated packages does not contain the latest bug fixes or new features.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:
