It’s your system problem.
try reinstall python-dev

sudo apt remove libpython3.x-dev // x is version which you installed
sudo apt install libpython3.8-dev

If it doesn’t work, reinstall the system

I followed your advice and ran sudo apt remove libpython3.8-dev, but when I type sudo apt install libpython3.8-dev it prints {package ‘libpython3.8-dev’ has no installation candidate}.

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

Is your os ubuntu 20.04 ?

try

sudo apt-get update
sudo apt-get upgrade
sudo apt install python3-pip

then reinstall libpython3.8-dev
