react native项目运行报错
Unhandled JS Exception: Unexpected identifier ‘_classCallCheck’. import call expects exactly one argument. no stack
解决办法
1.升级 metro-react-native-babel-preset 版本 为0.59.0
2.修改babel.config.js 生效
之前:
module.exports = {
presets: ['module:metro-react-native-babel-preset'],
};
修改后:
module.exports = {
presets: [['module:metro-react-native-babel-preset', {
unstable_disableES6Transforms: true
}]],
};
然后重新运行项目即可
