Question

在我的项目文件夹中尝试运行“ npm run start”时，我不断收到此错误消息：

myLaptop:app-name userName$ npm run start

> app-name@0.1.0 start /Users/userName/My Documents/app-name
> node scripts/start.js

Cannot destructure property `compile` of 'undefined' or 'null'.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! app-name@0.1.0 start: `node scripts/start.js`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the app-name@0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/userName/.npm/_logs/2018-12-09T16_26_00_758Z-debug.log

基本代码是从此Medium post复制而来的，并且在我开始工作时就可以使用，但是我想我可能已经更改了某些地方，使它无法正常运行。

请将webpack-dev-server的版本降级为3.0.0。

由于对等方的依赖性，webpack-dev-server 3.x仅与webpack 4.x兼容。

尝试使用最新的webpack版本，因为您使用的是2.x.x的webpack版本，因此最新版本是4.27.1

我希望这能解决问题。

尝试运行“ npm run start”脚本时出现“ errno 1”
