momentjs Deprecation Warning

Question

Moment.js运行时，刷新页面后出现Moment Deprecation Warning

用moment对象代替Date()对象，用toDate()转换成Date()对象，还是继续有错误

报错信息如下

Deprecation warning: dates accessor is deprecated. Use date instead.

这样问题应该如何处理。

Answer 1

答案很明显：你用的moment库旧了，使用了一个过时方法moment().dates，最新是用moment().date。（2.16之前的版本）
解决方式： 升级Moment库到最新版（目前2.22.2）
至于怎么升级，修改一下项目根目录下的package.json，找到其中的moment，换上最新版本号
