Learning from YouTube tutorials, I tried to make a whatsapp clone. I wanted to use babel cli and babel node to start the server in order to connect the database, so I wrote this code { "./node_modules/babel-cli/bin/babel-node.js --presets node8 ./server.js" } in the scripts, but it displays the above error. Please help me.

write this

"scripts": {
    "start": "node ./node_modules/babel-cli/bin/babel-node.js --presets node8 ./server.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  }, 

instead of this

"scripts": {
        "start": "./node_modules/babel-cli/bin/babel-node.js --presets node8 ./server.js",
        "test": "echo \"Error: no test specified\" && exit 1"
      },
