1.composer install或者其他操作报:

A version is required for an API group definition.

可能1：.env文件没有

2.laravel-admin 显示图片在图片地址前添加admin域名，例如：

127.0.0.1:8000/admin/127.0.0.1:8000/uploads/images/1.jpg

原因：.env设置APP_URL错误

错误：APP_URL=127.0.0.1:8000

正确：APP_URL=http://127.0.0.1:8000

3.模仿dingoapi 返回分页


 $dataList = $paginator->transform(function ($item){
                 $data = $transformer->transformData($item);
                 return $data;
          });

4.laravel-admin上传多张图片

controller：

 $form->multipleImage('images', '上传图片');

model：

 public function getImagesAttribute($value){ 
    $array = explode(',', $value); 
    return $array; 
 } 
 public function setImagesAttribute($value){ 
    $this->attributes['images'] = implode(',', $value); 
 }

5.接口请求数据库写字段写入不进去

model中$fillable添加字段

6.composer 无法下载扩展文件的问题

 [Composer\Downloader\TransportException]                                                                                     
  The "https://packagist.laravel-china.org/packages.json" file could not be downloaded: Peer certificate CN=`*.phphub.org' di  
  d not match expected CN=`packagist.laravel-china.org'                                                                        
  Failed to enable crypto                                                                                                      
  failed to open stream: operation failed

原因：composer 全局下载换成中国镜像.

解决：下载源换回默认。修改 composer 配置

composer config -g repo.packagist composer https://packagist.phpcomposer.com

7.报bootstrap/cache directory must be present and writable.错误

mkdir cache

php artisan cache:clear

8. 报这个错误 Missing BC Math or GMP extension.

Hashids requires either theBC MathorGMPextension in order to work.

yum install php-bcmath
chown -R -v nginx:nginx /run/php-fpm/php-fpm.sock

9.file_put_contents(/): failed to open stream: Permission denied

1）php artisan cache:clear 2）chmod -R 777 storage

10.composer update报错
