[Slackbuilds-users] libinput-1.15.4 build fails: no pkg_resources

[Rich Shepard]

I'm running Slackware-14.2/x86_64 and Python3-3.8.2 with current versions of
libinput requirements and libinput-1.15.3. When I try to build -1.15.4 the
process fails here:

Traceback (most recent call last):
   File "/usr/bin/meson", line 6, in <module>
     from pkg_resources import load_entry_point
ModuleNotFoundError: No module named 'pkg_resources'

Sure enough, I cannot import pkg_resources in Python3.

A StackOverflow thread taught me that pkg_resources is distributed with
setuptools; I have three of 'em here: python-setuptools-22.0.5-x86_64-1[1],
setuptools-git-1.1-x86_64-1_SBo, and setuptools-scm-3.3.3-x86_64-1_SBo. An
answer to the SO question says that:

"July 2018 Update

"Most people should now use pip install setuptools (possibly with sudo).

"Some may need to (re)install the python-setuptools package via their
package manager (apt-get install, yum install, etc.).

"This issue can be highly dependent on your OS and dev environment. See the
legacy/other answers below if the above isn't working for you.

"Explanation

"This error message is caused by a missing/broken Python setuptools package.
Per Matt M.'s comment and setuptools issue #581, the bootstrap script
referred to below is no longer the recommended installation method.

"The bootstrap script instructions will remain below, in case it's still helpful to
anyone."

Advice needed,

Rich

python3-setuptools.
