修飾器報(bào)錯(cuò)

Module parse failed: Unexpected character '@' (50:4)

You may need an appropriate loader to handle this file type.

webpack.config.js文件也配置了

rules:?[{
????test:?/\.(js|jsx)$/,
????exclude:?/node_modules/,
????use:?{
????????loader:?'babel-loader',
????????options:?{
????????????presets:?['env','react'],
????????????plugins:?['transform-decorators-legacy','transform-class-properties']
????????}
????}
}]

index.js

class?Store{
????@observable?array?=?[];

}

請問還會(huì)報(bào)錯(cuò)的原因是什么
