I am trying to install adafruit-circuitpython-mlx90640, a library for the MLX90640 thermal camera. When I run sudo pip install adafruit-circuitpython-mlx90640 I get an error that no matching distribution is found for Adafruit-Blinka. So I tried to pip install Adafruit-Blinka and get the same error: no matching distribution is found for Adafruit-Blinka. Any ideas on how to get it to work?

One more thing that I have tried: The default version on my raspberry pi is 3.4. I have installed Berryconda, which is a version of Anaconda for the RPi. In Berryconda the Python version is 3.6 and pip (not pip3) works with it. Pip3 installs Adafruit-Blinka but it goes into python 3.4. I would like it to be installed into Python 3.6. I think if I were to point Pip3 to the Berryconda version of Python, my problem would be solved (but not sure).

    pip is for python 2. If you want to install it for Python 3, use pip3. Commented Jul 1, 2020 at 15:58

As ben_nuttall says, you must use pip3. Circuitpython is Python 3 only!

sudo pip3 install adafruit-circuitpython-mlx90640
