我是vue.js的新手，我无法将新用户添加到用户数组中。当我在提交时调用函数时，我使用console.log记录"this. user"，但我没有得到另一个包含新用户的框，也没有在用户数组中找到新用户。
我确实收到一条错误消息，内容如下：

vue.runtime.esm.js?c320:3049 Error: Cannot find module './undefined'

有人知道我该怎么解决吗

通过执行this.users.push({ user: this.user })，你实际上是在推送一个以'user'为键、'this.user'为值的对象：

改做this.users.push(this.user)！

尝试在装载或创建时从userData进行深度克隆，而不是在"数据"中引用。
就像这样：

data() {
    return {
      users: []
 }
}
mounted() {
  this.users = structuredClone(userData)
}

如果成功了告诉我。
