得到错误！ 缺少脚本：开始于 <npm start> 命令

Question

When I run npm start, I get the dreaded "npm ERR! missing script: start"

---

Already tried changing the "start" line in the package.json in every way shown here and on Google going back a full year.

Also tried installing just about every stable node/npm stable release from the current to 12.x. Deleted yarn just to be sure. Wnet back to current release.

Ran everything from npm init to npm create-react-app [project folder] node_modules are there.

The script for run does show up in the package.json.

Deleted the project directory,deleted the repository and re-cloned the depository fresh.

I've tried just about everything. I hope you all can help. npm start won't run, so I'm basically coding blind - nothing to the monitor, no Chrome React devTools.

Answer 1

Your scripts section looks off in your package.json perhaps you can change your start script to the following:

"start": "react-scripts start",

For full reference your scripts section should look similar to this, assuming you're trying to use react bootstrapped with the create-react-app cli:

package.json

"scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }

Hopefully that helps!
