I am going through a tutorial, but it is not working and I can’t figure out why.
It is “Python + JavaScript – Full Stack App Tutorial”
https://www.youtube.com/watch?v=PppslXOR7TA
I downloaded the files whole sale, but when I use ‘npm run dev’ command it says
usage: vite [options]
A simple and minimal static site generator.
positional arguments:
{init,new,build,serve}
Options to help create, build and serve your project.
options:
-h, –help show this help message and exit
-v, –version show program’s version number and exit

When I try to go through the whole thing myself, it has a problem with line 70 is ContactList.jsx
{contacts.map((contact) => (
error is
Uncaught TypeError: Cannot read properties of undefined (reading ‘map’)
It looks like contact doesn’t exist, and it is empty because I am just starting the program, but I have no idea what the problem could be.
