[Solved] G++ Error: Command ‘g++‘ not found, but can be installed with:

And you go through it

sudo apt-get install g++

It shows that you have installed the latest version of G + +, but you just can’t use G + +++

In fact, I accidentally deleted the G + + script file under/usr/bin, leaving a bunch of G + + 7.4, G + + 4.8, etc. enter the command line:

cd /usr/bin
sudo ln -s g++-7.4 g++

That’s all
