alpine package py-pip missing

Im trying to install python pip in my alpine using Docker compose file but get the following error.

ERROR: unsatisfiable constraints:
  py-pip (missing):
    required by: world[py-pip]
ERROR: Service 'web' failed to build: The command '/bin/sh -c apk add py-pip' returned a non-zero code: 1

Solution 1:

Do update first:

apk add --update py-pip

Or:

apk update
apk add py-pip

Solution 2:

For python3 on alpine edge:

apk add py3-setuptools

Solution 3:

You have to use appropriate pip version depending on Alpine branch:

• Alpine v3.12 or newer, use apk add --update py3-pip
• Alpine v3.5 - v3.11, use apk add --update py2-pip
• Alpine v3.3 - v3.4, use apk add --update py-pip
