gcc: error trying to exec 'cc1plus': execvp: No such file or directory

This link helped me to fix this issue.

You need to run below command to get g++ installed

yum install gcc-c++

The following worked for me:

sudo apt-get install g++

The routine commands that saved me time after time for such errors:

sudo apt update
sudo apt upgrade
sudo apt install gcc python3-dev python3-pip libxml2-dev libxslt1-dev zlib1g-dev g++

Hope it works.
