How to solve Installing pip is not working in python < 3.6 ?

solutions

question: Installing pip is not working in python < 3.6

solution:1

pip 21.0 dropped support for Python 2 and 3.5. The later versions require Python 3.6+. The syntax f"" is supported by Python 3.6+.

To install pip for Python 2.7 install it from https://bootstrap.pypa.io/pip/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"

The last command is to upgrade to the latest supported version. For Python 2.7 the latest supported is currently pip 20.3.4.

For Python 3.4 install from https://bootstrap.pypa.io/pip/3.4/ . For Python 3.5 — https://bootstrap.pypa.io/pip/3.5/ .

For Python 3.4 the upgrade command is

- python -m pip install --upgrade "pip < 19.2"

solution:2

I have also tried all thing but my solution was download old get-pip version and install.

  1. download: curl -O https://bootstrap.pypa.io/2.7/get-pip.py the file get-pip.py
  2. install: python get-pip.py or python2 get-pip.py
  3. enjoy

This is worked on Debian systems.


Edit: A better solution is always to install a Python version that is long supported. If at all you need to work with an older version – only then must one resort to the above workaround
