Installation on Debian 10 (buster) failed

[googlegitter]

I tried to follow the installation description but it will not work.

First i have to install the following packages:
python3-pip python3-distutils python3-setuptools python3-wheel

Then i could start

# python3.7 -m pip install .

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-el3apevh/PyQt5/

that failed!

Afterwards i tried to manually install the packages one after another with the given error messages trying to start "python3.7 nanovna-saver.py":
python3.7 -m pip install numpy
python3.7 -m pip install scipy
python3.7 -m pip install serial

But the last package could not be fixed:

$ python3.7 nanovna-saver.py

# python3.7 -m pip install serial.tools
Collecting serial.tools
Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/serial-tools/

Please - what mystic must be done to get it running?

I could found the solution here: espressif/esptool#350

So python3.7 -m pip install pyserial did fix it.
Now it starts. :-)

also upgrading pip before installing should fix this
