问题描述
我正在跟着这个webpack4/react教程:
I am following along with this webpack4/react tutorial:
https://www.youtube.com/watch?v=deyxI-6C2u4
我一直严格遵循直到他运行npm的那一部分开始.不同之处在于,他的应用程序运行了,而我的却得到了错误:
I have followed it exactly up until the part where he runs npm start. The difference is, his app runs, and mine gets the error:
找不到模块'@ babel/core'
Cannot find module '@babel/core'
完整错误:
ERROR in ./src/index.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):

我尝试重新安装babel-core,但仍然找不到.这是我的package.json:
I have tried to reinstall babel-core but is still not being found. Here is my package.json:

我的webpack.config.js:
My webpack.config.js:
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
entry: './src/index.js',
output: {
path: path.join(__dirname, '/dist'),

},
module: {

test: /\.js$/,

},
plugins: [
new HtmlWebpackPlugin({
template: './src/index.html'
})
]
}

任何人都知道发生了什么事吗?谢谢.
Anyone know whats going on? Thanks.
推荐答案
尝试运行此代码.
npm install @babel/core --save
babel更改了他们的包裹,因此您的babel-core
将与@babel/core
不同.
babel changed their package so your babel-core
will not be the same as @babel/core
.
