当您缺少结束方括号或额外方括号时，将生成此类错误，因此按ctrl+shift+f将代码格式化为可视代码，以查看缺少的方括号。

这是一个语法错误。发布整个代码。@hongdeveloper您好，我发布的完整代码在您的代码中缺少最终“}”。*不变冲突：元素类型无效：需要字符串（对于内置的“组件”）或类/函数（对于复合组件）但是得到：object。您可能忘记了从定义组件的文件中导出组件，或者您可能混淆了默认导入和命名导入。“我明白了，您可以帮助您导入ActionButton，但您在render方法中只使用了一些未知的按钮组件。考虑用ActuutBut纽替换按钮。@文达我更新了答案，所以你可以只复制代码。我试过了，但是我仍然得到相同的“不变违反”。error@Venda，我喜欢吃零食，这是正确的。请参阅此链接（），您应该重新加载项目。@Venda，您没有使用
