Installation environment issue

[beaker1306]

Firstly let me say how brilliant this project is. At the beginning of 2024 I put 2 of these together and they've been working brilliantly. So a massive thank you for sharing this project.
Everything has been working fine until the prices stopped updating. Unbeknownst to me is was the AGILE_TARIFF_BASE which required updating. So I just assumed something had corrupt and happily went about reinstalling everything from scratch.
This issue I've run into is when I run the curl https://get.pimoroni.com/inky | bash it gets all the way to the end until it fails with an environment error as follows

python3-numpy is required
Installing python3-numpy...
python3-pil is required
Installing python3-pil...
python3-lxml is required
Installing python3-lxml...
python3-smbus is already installed

Installing Inky pHAT & wHAT library for Python 3...

error: externally-managed-environment

× This environment is externally managed
╰─> 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.

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.
Python 3 library install failed!
If problems persist, visit forums.pimoroni.com for support

I admit that any further than following instructions bemuses me at the moment so I wondered if anyone else has come across this issue and what did you do to solve it?

Any help appreciated please. //

Hi beaker1306, I recently installed this and I had some problems. You should use virtual env.

Here some ideas how to fix it:
https://stackoverflow.com/questions/75608323/how-do-i-solve-error-externally-managed-environment-every-time-i-use-pip-3

or you can modify .bashrc to turn on permanently venv like this: line source [~/.virtualenvs/pimoroni/bin/activate] should be added into the .bashrc file in the /home/pi users folder.

I had to modify the following lines:
294 size issue
font = ImageFont.truetype (FredokaOna, 72) --- original
font = ImageFont.truetype (FredokaOna, 62) --- modified

from line 296 each w and h to _, _, w, h and the font.getsize to font.getbbox
w, h, = font.getsize(message)
_, _, w, h = font.getbbox(message)

354 chart_base_loc = 104 + lowest_price_next_24h*pixels_per_h - 2 # if we have any negative prices, shift the base of the graph up!
354 chart_base_loc = chart_base_loc + lowest_price_next_24h*pixels_per_h - 2 # if we have any negative prices, shift the base of the graph up!

398 time_of_cheapest_formatted = "at " + (str(time_of_cheapest.time())[0:5])
399 font = ImageFont.truetype(FredokaOne, 16)
400 draw.text((right_column,101), time_of_cheapest_formatted, inky_display.BLACK, font)
398 time_of_cheapest_formatted = "Updated " + (str(the_now_local.time())[0:5])
399 font = ImageFont.truetype(FredokaOne, 11)
400 draw.text((right_column,105), time_of_cheapest_formatted, inky_display.BLACK, font)

Also I modified little bit the crontab

I had to disable line 372 due to error message. "ValueError: x1 must be greater than or equal to x0"
At the moment the chart is not working
372 draw.rectangle((pixels_per_wi,chart_base_loc,((pixels_per_wi)-pixels_per_w),(chart_base_loc-scaled_price)),ink_color)

I hope this helps

The install part for the phat has changed.

git clone https://github.com/pimoroni/inky
cd inky
./install.sh
Once that's all done, type sudo reboot to reboot your Pi and apply the changes to the Pi's interfaces.

[quote]The install script enables and configures I2C and SPI and also (optionally) will set up a virtual environment for you, which you will need to be able to install Python packages in recent versions of Pi OS. If you'd like to read more about virtual environments check out the Raspberry Pi documentation or our overview.[/quote]
