webpack4_@babel/core报错"Could not find plugin "proposal-class-properties""

目录

错误详情

  • 在使用babel-loader做js兼容性处理时，下载了如下三个包：
    "@babel/core": "^7.8.4",
    "@babel/preset-env": "^7.8.4",
    "babel-loader": "^8.0.6",
  • webpack.config.js配置如下：
{
            test: /\.js$/,
            exclude: /node_modules/,
            loader: 'babel-loader',
            options: {
                presets: ['@babel/preset-env']
            }
        }
  • 执行webpack报错：

ERROR in ./src/js/index.js
Module build failed (from C:/Users/12203/Desktop/daily/node_modules/babel-loader/lib/index.js):Error: [BABEL] C:\Users\12203\Desktop\daily\2.3\js兼容性处理\src\js\index.js: Could not find plugin "proposal-class-properties". Ensure there is an entry in ./available-plugins.js for it. (While processing: "C:\Users\12203\Desktop\daily\node_modules\@babel\preset-env\lib\index.js")

错误解决方法

1.配置package.json

    "resolutions": {
        "@babel/preset-env": "^7.8.4"
    }

在package.json中添加此配置

2.删除package-lock.json与node_modules文件夹

3.执行npm install重新安装
