Ionic Python2 Erreur: Non trouvé: Python2

in my ionic project it is so old and it need python for build

to do this first we need o install python 2.7 

then set the path for npm node config

like this
we also need node-gyp

=> npm i -g node-gyp 
Set the path =>. node-gyp --python  /usr/local/bin/python2.7
