Enviro Hat Modules not found

I am trying to use a new Enviro Hat with both Pi 4 and Pi Zero 2.
The Pi’s are running Buster.
I have try installing with both:
curl -sSL https://get.pimoroni.com/enviroplus | bash
and
git clone https://github.com/pimoroni/enviroplus-python
cd enviroplus-python
sudo ./install.sh

In both case I get Module not found errors for all sensors:
eg ImportError: No module named bme280

With much Googling I had to run the following:
sudo pip install ltr559
sudo pip install ST7735
sudo pip install pms5003
sudo apt install clang -y
sudo pip install enviroplus
pip install pimoroni-bme280==0.0.2

The examples now run but why did the recommended installation process not work? What am I doing wrong?

Thanks,
Julian

I’ve got the same issue. LCD is working just fine. But the sensors seems to malfunctioning. Running the same commands did not help.
Trying on a Pi400 and 3
