laravel5.3搭建過程中出現問題

composer install命令出錯-->

 [Composer\Downloader\TransportException]
  Your configuration does not allow connections to http://packagist.phpcomposer.com/packages.json. See https://getcom
  poser.org/doc/06-config.md#secure-http for details.

解決方法:因為鏡像使用用的是http，而原地址是需要https，所以配置下關掉https就好了。

    {  
        "config": {  
            "secure-http": false  
        }  
    }

解決方案:修改php.ini開啟openssl拓展

 

Laravel 出現"RuntimeException inEncrypter.php line 43: The only supported ciphers are AES-128-CBC and AES-256-CBC with the correct key lengths."問題的解決辦法——>

首先在cmd命令行下定位到項目所在的根目錄下，接着輸入：

php artisan key:generate 

這時候項目根目錄下的.env文件里的APP_KEY應該會有值了：

若沒有，將上面的key輸入進去
