Answer 1

Make sure a bash executable actually exists at the path output by npm. You can update the path that npm uses for the script shell using:

npm config set script-shell "C:\\Program Files\\git\\bin\\bash.exe"

or check your current script-shell with:

npm config get script-shell

Answer 2

npm don't like the space in C:\Program Files\git\bin\bash.exe when he try to spawn bash

try to change the location of bash.exe in a path without space

don't forget to update your PATH env
