我应该在我的 package.json 文件中放入什么来让“纱线开始”工作？

Question

I am currently following a tutorial on how to setup and use toastify, and I have followed the tutorial up to the point where the person in the tutorial inputs yarn start into the terminal, and his code output opens in his browser. but when I do it the terminal outputs this: yarn run v1.22.4 warning package.json: No license field error Command "start" not found. info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command. yarn run v1.22.4 warning package.json: No license field error Command "start" not found. info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command. and nothing happens. I followed the tutorial exactly and the person in the tutorial does not do anything with packag.json and his code still works. Why isn't my code working? and how do I fix it?

Answer 1

You should have a start script defined in your package.json

Ex:

{
  "scripts": {
    "start": "You should write your start script here"
  }
}

Answer 2

I've been in the same situation before， Maybe you'd better check that you're running the command in the right directory.

Answer 3

you should write 'start' in package.json

if you have a react-native app,

"scripts": {
"start": "react-native start"
}

Answer 4

npm run start with the definition at the package.json like this:

"start": "react-scripts start",
