Error: Un-handled python exception while installing through vcpkg about meson HOT 7 CLOSED

@amitdo,

Actually Ubuntu bionic provides backports of 3.7 and 3.8

@amad-haseeb,

Ubuntu mutilates their python package and only half of it is installed by default. You need to get the other half with apt install python3-distutils IIRC (plus another couple of packages for the other missing bits).

from meson.

Main binary: /usr/bin/python3

In Ubuntu 18.04, python3 points to python 3.6 which is not supported in meson 1.3.

Also, the cmake version in the Ubuntu 18.04 repo is too old and is not supported by meson 1.3.

@amitdo,
The system alternative were updated to point to python 3.7 instead of 3.6, so python3 was pointing to 3.7.5.

:

@eli-schwartz: Thanks mate, I was missing the one you mentioned, rest were installed,
those other packages are python3.x-dev and python3.x itself.

PS: It compiled successfully after installing python3-distutils

from meson.

The other packages I'm referring to are things like "venv" (important but not specifically for meson). There's also tkinter but to be fair lots of distros make that optional.

Okay, But I was building these packages inside a container so it was already a contained environment.

@amitdo,

Yes, I know, but this does not invalidate what I said. python3 will still point to the default python version in the distro, which is python 3.6, after installing python 3.7/3.8.

from meson.

As the OP noted, Ubuntu itself was configured to select the backported 3.7 as /usr/bin/python3 using standard dpkg technologies.

Meson CI does the same thing, as it happens, on our single runner for Ubuntu Bionic.
