Can´t start the server created from the express.js generator

I am trying to setup a express.js server using there generator. I have followed the documation and I have succesfully created the basic structure. However if I try to run the given command (SET DEBUG=transcriptverificationserver:* & npm start) to start the server I always get the following error:
npm ERR! Missing script: "start"
npm ERR!
npm ERR! Did you mean one of these?
npm ERR! npm stars # View packages marked as favorites
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR! npm run

I assume its an issue within the package.json file. The script part looks as following:
"scripts": {
"start": "node ./bin/www"
},
I haven´t change anything in the files or structure and I was simply copying the commands from the documentation (https://expressjs.com/en/starter/generator.html)
Thanks for any help in advance

I have tried it again and this time everthing works. I am not sure what has happend before but I might have used the old installation method.
$ npm install -g express-generator
$ express
With my secound try I ensured to use the new method:
$ npx express-generator

I also use Ubuntu 20.04 and I just had the same problem as you.
Here I just updated the npm package (via synaptic).
After this, sudo npm i -g #angular/cli worked ok.
This point solved my problem, maybe that can help you too.

I had a similar problem on Ubuntu 20.04, after I install nodejs (in my case 14.17 stable) and try install Angular.
I went to the directory /usr/bin and deleted the ng file,
after sudo npm i -g #angular/cli.
So ng --version to see if installed ok.
I hope help yo, bye.
