webpack中react一直配置失败?

Question

错误信息如图

想问一下是不是少了什么配置?

Answer 1

还需要安装npm install --save-dev babel-preset-react,然后在webpack中配置   {      test: /\.js$/,     exclude:/node_modules/,     loader:'babel-loader',     query:{       presets:['react']    }

Answer 2

少了babel的配置        {                           test:/\.jsx?$/,             loader:'babel',             query:{                 presets:['es2015','react']             }         }记得先安装babel-preset-es2015,babel-preset-react
