在使用 react-native run-android
打开我的项目后,我在我的 android 程序上使用 React-Native ,错误发生了。同样的错误信息出现了两次。
Unexpected identifier '_classCallCheck'.import call expects exactly one argument
Unexpected identifier '_classCallCheck'.import call expects exactly one argument

no stack
我用谷歌搜索了这个并尝试了一些解决方案,但仍然无法解决。这是我发现的类似问题:

我已经尝试过这个错误:
gradlew clean
react-native start --reset-cache
npm install -g react-native-cli

伙计们,我刚刚解决了这个问题。这是链接。https://github.com/babel/babel/issues/14139
从:
module.exports = {
presets: ['module:metro-react-native-babel-preset'],
};
至:module.exports = {
presets: [['module:metro-react-native-babel-preset', {
unstable_disableES6Transforms: true
}]],
};
最佳答案
我遇到了同样的问题,上面的步骤不起作用,所以我将 metro-react-native-babel-preset 从 0.56.0 更新到 0.59.0 并且它起作用了。
