我克隆了我的旧项目并运行npm install,然后我跑了ionic serve
我发现了这个错误
[ERROR] @ionic/app-scripts is required for ionic serve to work properly.
Looks like @ionic/app-scripts isn't installed in this project.
This package is required for ionic serve in ionic/angular 4 projects.
我想添加两个时间戳,如下例所示:
$created_at = "2018-07-23 12:15:43";
$is_expired = $created_at + 30mins;
内容$is_expired应该是2018-07-23 12:45:43
