小编mik*_*olu的帖子

In my Angular-12 project I installed file-saver:

npm install file-saver@2.0.5

npm install --save exceljs

ng generate service services/export-excel

Then in the export-excel service, I added:

import * as fs from 'file-saver';

I got file-saver highlighted

with this error:

Could not find a declaration file for module 'file-saver'. 'c:/xampp/htdocs/myapp/node_modules/file-saver/dist/FileSaver.min.js' implicitly has an 'any' type. Try npm i --save-dev @types/file-saver if it exists or add a new declaration (.d.ts) file containing declare module 'file-saver';

But I didn't use:

@types/file-saver

How do I …

使用 Laravel-5.8 发送通知，我收到此错误：

在我的 Laravel 5.8 应用程序中，我有：

config/app.php

'date_format' => 'd/m/Y',
'date_format_js' => 'dd/mm/yy',

模型

use Carbon\Carbon;

class HrHolidayDate extends Model
{
    protected $table = 'hr_holiday_dates';

    protected $fillable = [
        'holiday_name',
        'holiday_date',

    ];

    protected $dates = [
        'holiday_date'
    ];


    protected $casts = [];


    public function setHolidayDateAttribute($input)
    {
        $this->attributes['holiday_date'] =
            Carbon::createFromFormat(config('app.date_format'), $input)->format('Y-m-d');
    }


    public function getHolidayDateAttribute($input)
    {
        return Carbon::createFromFormat('Y-m-d', $input)
            ->format(config('app.date_format'));
    }
}

我尝试在 Blae 视图中对其进行格式化，如下所示：

view

@foreach($holidays as $key => $holiday)
    <td>
        {{Carbon\Carbon::parse($holiday->holiday_date)->format('d-m-Y') ?? '' }}
    </td>
@endforeach

当我想渲染视图刀片时，出现此错误：
