1623544 - `mach install-moz-phab` after `mach bootstrap` fails due to missing `python3-pip` on Debian

Status: RESOLVED FIXED

(Firefox Build System :: Bootstrap Configuration, defect, P3)

Description

[Nick Alexander :nalexander [he/him]]

Setting up a new Debian 10 (buster) box, after cloning and running bootstrap I still don't have enough. Maybe we should install python3-pip during bootstrap as well?

nalexander@nanger:~/Mozilla/gecko$ ./mach install-moz-phab
 0:00.29 Installing moz-phab
Error running mach:

    ['install-moz-phab']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.
You can invoke |./mach busted| to check if this issue is already on file. If it
isn't, please use |./mach busted file| to report it. If |./mach busted| is
misbehaving, you can also inspect the dependencies of bug 1543241.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

FileNotFoundError: [Errno 2] No such file or directory: 'pip3': 'pip3'

  File "/home/nalexander/Mozilla/gecko/tools/phabricator/mach_commands.py", line 71, in install_moz_phab

Python started bundling pip with Python 3.4 (source) however: "Appropriately versioned pip commands may also be available" (emphasis mine).

Does python3 -m pip work? It should output the help for pip.

I just installed Debian 10 to test this - python3 -m pip doesn't work either.
Debian have decided to remove a core feature of Python from their Python package. I'm at a loss for words.

Sorry for not helping here -- technically I've been on parental leave so things have been pretty wild re: child-care.
