Error Installing Adafruit_DHT for python on Raspberry Pi 400

Question

I need to use a DHT-11 for a school project and I am getting a weird error trying to install the packages for it.

Following the instructions I used sudo pip3 install Adafruit_DHT and that resulted in this output:

sudo pip3 install Adafruit_DHT

  note: This error originates from a subprocess, and is likely not a problem with pip.

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

I also tried running sudo pip3 install Adafruit_DHT --install-option="--force-pi" which output:

WARNING: Disabling all use of wheels due to the use of --build-option / --global-option / --install-option.

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv

However, when I run my python code I get this

  import Adafruit_DHT
ModuleNotFoundError: No module named 'Adafruit_DHT'

I've updated pip and the setup tools and I'm pretty new to all of this. This assignment is due soon and I just want to get this DHT working. Thanks in advance.

Answer 1

I had the same problem when I tried to install the Adafruit_DHT on my py.

When I reinstalled wheel with:

sudo python3 -m pip install --upgrade pip setuptools wheel

and then:

sudo pip3 install Adafruit_DHT

it worked for me.
