Not able to build the project.

[ejcasas]

Hi Team, I need help, I am not able to build the project, I uninstall/install the modules and follow up all of the instructions (clean, rebuild node-sass, etc.), but I've got the same error:

@ejcasas and @Naimas
Your cli uses the wrong version of python to execute that part of the script.

npm ERR! gyp verb which failed Error: not found: python2
Indicates that python2 path is not set so it uses python 3 but than fails.

npm ERR! gyp verb which succeeded python C:\Python310\python.EXE

This shows that it uses the python 2.x print function (3.x uses print() ):
npm ERR! gyp ERR! stack import sys; print "%s.%s.%s" % sys.version_info[:3];

So you need to set that straight first.

@jdh009 I am having the same problem as OP. I have installed Python 2.7, made a copy of the .exe named "python2.exe", and registered the path in PATH. Now I'm getting a different cascade of errors:
