Running into this when trying to install (macOS 10.12.6)

$ brew install socat datawire/blackbird/telepresence

That's unusual. The failing step is venv = virtualenv_create(libexec, "python3"), which is just an application of Homebrew's Python machinery.

Can you try installing a different package that uses Python, e.g., brew install awscli?

Possibly related is that Homebrew recently upgraded their Python3 to version 3.7. Maybe (re-)installing Homebrew's Python3 explicitly will address this problem.

@liorsbg Did you succeed in getting Telepresence installed?

I am running into this same issue. Tried installing awscli also, but didn't work.

[ravihugo]

I found that I needed to run this first:

brew postinstall python3
pip3 install setuptools

Then the command: brew install socat datawire/blackbird/telepresence works just fine

@ravihugo This solution worked for me as well, attempting to install QGIS 3 brew install osgeo/osgeo4mac/qgis3
