So... (from pyvenv):
(weewx) bcm2709_/home/crichmon> pip3 cache list
Cache contents:
- CT3-3.3.3-cp311-cp311-linux_armv7l.whl (195 kB)
- args-0.1.0-py3-none-any.whl (3.3 kB)
- clint-0.5.1-py3-none-any.whl (34 kB)
- ephem-4.1.5-cp311-cp311-linux_armv7l.whl (1.7 MB)
- pillow-10.2.0-cp311-cp311-linux_armv7l.whl (1.0 MB)
My xterm history doesn't go back far enough to show the log when the pillow
build failed. It sounds like that
should have included getting libfreetype6 in the process.
As a reminder; this OS version or more likely python version doesn't
support adding non-OS supported python
modules (again, error not in xterm history), so anything the OS doesn't
support natively HAS to be in a pyvenv.
I'm guessing the only way to figure this out is to start from scratch. I'm
up for it if you think it's required.
And, FWIW, I tried this (outside pyvenv):
bcm2709_/home/crichmon> pip3 cache list
Cache contents:
- CT3-3.3.3-cp311-cp311-linux_armv7l.whl (195 kB)
- args-0.1.0-py3-none-any.whl (3.3 kB)
- clint-0.5.1-py3-none-any.whl (34 kB)
- ephem-4.1.5-cp311-cp311-linux_armv7l.whl (1.7 MB)
- pillow-10.2.0-cp311-cp311-linux_armv7l.whl (1.0 MB)
bcm2709_/home/crichmon> sudo tcsh
[sudo] password for crichmon:
root@bcm2709> cd
bcm2709_/root# pip3 cache list
No locally built wheels cached.
Here's how pip3 fails outside the pyvenv: (guessing this isn't news)
bcm2709_/home/crichmon> sudo pip3 install Adafruit_Blinka
error: externally-managed-environment
à This environment is externally managed
â°â> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.
If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.
If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.
See /usr/share/doc/python3.11/README.venv for more information.
note: If you believe this is a mistake, please contact your Python
installation or OS distribution provider. You can override this, at the
risk of breaking your Python installation or OS, by passing
--break-system-packages.
hint: See PEP 668 for the detailed specification.
Thx, Chris
