问题描述
在我删除 node_modules 文件并尝试重新安装 npm 包之前，我的项目运行良好.
on-rest my project was working great untill I delete my node_modules file and try to re-install npm package.
我收到此错误
./node_modules/react-event-listener/dist/react-event-listener.cjs.js
Module not found: Can't resolve '@babel/runtime/helpers/builtin/classCallCheck' in '/Users/suatkarabacak/Desktop/demarkedashboard/node_modules/react-event-listener/dist'
我的 package.json 看起来像这样.
My package.json is looking like this.
{
"name": "demo",
"version": "0.1.0",
"private": true,
"dependencies": {
"admin-on-rest": "^1.4.1",
"aor-dependent-input": "^1.2.0",
"aor-parseserver-client": "0.3.0",

"react-dom": "^15.6.2",
"react-image-lightbox": "^4.6.0",

"@babel/runtime": "^7.0.0-beta.56",
"aor-color-input": "^1.2.1",
"babel-polyfill": "^6.23.0",

},
"homepage": "demo.html",
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}
没有内置文件夹.
可能是什么问题?
推荐答案
由于 Babel 7.x 仍然是 Beta 版本，昨天发布的 beta.56 发生了重大变化.
Since Babel 7.x is still a beta version, there was a breaking change in beta.56, which was released yesterday.
"@babel/runtime": "^7.0.0-beta.56",
如果你使用的是测试版的东西，在你的版本号中使用 ^ 是危险的，因为这意味着它会接受任何最新的版本，无论它是否真的兼容以前的测试版.
If you're using a beta version of something, it is dangerous to use ^ in your version number, because that means it will accept any recent version, whether or not it is actually compatible with previous beta versions.
由于 react-scripts 使用 https://github.com/facebook/create-react-app/blob/1407287839f94151cec729bd89441d4eee7d9dd3/packages/babel-preset-react-app/package.json#L28
"@babel/plugin-transform-runtime": "7.0.0-beta.46",
你应该有
"@babel/runtime": "7.0.0-beta.46",
在您自己的 package.json 中进行匹配.
in your own package.json to match.
