alpine package py-pip missing

For me --no-cache option worked.

apk add --no-cache py-pip

For python3 on alpine edge:

apk add py3-setuptools

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

Do update first:

apk add --update py-pip

Or:

apk update
apk add py-pip
