如何解决此webpack或babel错误？
我不明白终端对我说了什么！
也许这意味着webpack.config.js，但我无法理解。
我该怎么办？
这是错误代码。

这是webpack.config.js
module.exports = {
mode: 'production',
entry: './src/index.js',
output: {
path: __dirname + '/public',
filename: 'bundle.js'
},
module: {
rules: [
{
test: /.js$/,
loader: 'babel-loader',
exclude: /node_modules/,
options: {
cacheDirectory: true,
presets: ['es2015', 'react']
},
}
]
}
};
这是.babelrc
{
"presets": ["es2015"]
}
我希望这对你有效
.babelrc
{
"presets": ["react", "env"],
}
webpack.config.js
module.exports = {
mode: 'production',
entry: './src/index.js',
output: {
path: __dirname + '/public',
filename: 'bundle.js'
},
module: {
rules: [
{
test: /.js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader"
}
},
]
}
};
