How Can I Install pip on Python Versions Below 3.6?

pip Installation Issues in Python < 3.6

When attempting to install pip using the standard steps on bitbucket CI, you may encounter a SyntaxError. This error arises because pip 21.0 and later versions only support Python 3.6 and above, as they utilize syntax not supported in earlier versions.

For Python 2.7 and 3.5, you'll need to install pip from the appropriate URL:

• Python 2.7: https://bootstrap.pypa.io/pip/2.7/
• Python 3.5: https://bootstrap.pypa.io/pip/3.5/

To install pip for Python 2.7:

- curl -O https://bootstrap.pypa.io/pip/2.7/get-pip.py
- python get-pip.py
- python -m pip install --upgrade "pip < 21.0"

Note that the last command upgrades pip to the latest supported version for Python 2.7, which is currently pip 20.3.4.

For Python 3.6 or above, the installation can proceed as usual. However, remember that you cannot use pip 21.0 or later on older Python versions due to the syntax incompatibility.
