Wrong version of pip in virtualenv

Question

I have defined a Python v-env and activated it through:

python3 -m venv myvenv
source myvenv/bin/activate

Before running this command, my pip3 version is 19.0.2, but once the command is run, the version changes to 18.1. What am I doing wrong?

is a screenshot from my terminal.

Editing this answer to serve as placeholder and preserve the comments, but:

This question is answered in this previous question, and is therefore a clear duplicate:

The relevant section:

It is an expected behavior. python -m venv calls python -m ensurepip to install pip and This answer shows that ensurepip would only install the bundled version even with --upgrade option. There isn't any official option to update the bundled pip and setuptools.

The referenced question from that question:

`python -m ensurepip --upgrade` does not seem to be upgrading pip and setuptools
