react native項(xiàng)目運(yùn)行報(bào)錯(cuò)
Unhandled JS Exception: Unexpected identifier ‘_classCallCheck’. import call expects exactly one argument. no stack
解決辦法
1.升級(jí) metro-react-native-babel-preset 版本 為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
}]],
};
然后重新運(yùn)行項(xiàng)目即可
