Laravel自学第一课:laravel下载与安装

本地安装laravel,php环境要配置好,推荐xmapp一键搭建。

1、程序包直接从官方下载,官方开源地址:https://github.com/laravel/laravel(当然也可从此网站:http://www.golaravel.com/download/ 下载一键安装包,下载下来就可以看到页面,这里不讨论)。

2、解压后的文件夹放置本地环境目录,访问http://localhost/laravel/是无法访问的,laravel将起始页面放在了public目录,访问如下地址开始吧。

http://localhost/laravel/public/,很不幸,报错了,如下图,意思是没有找到vendor目录下的autoload.php目录。当然你是怎么也找不到这个文件的,因为根本就没有。

 

3、接下来需要安装composer(自行安装吧),运行命令行,转到laravel目录,输入

composer install

命令,如下图:

等待安装完成,laravel文件夹就出现了wendor目录。

4、你发现你依然不能访问,出现了两行大大的“Whoops, looks like something went wrong.”。这是我们没有开启debug,所以看不到错误提示。

打开laravel\config目录的app.php,修改

'debug' => env('APP_DEBUG', false), 为 'debug' => env('APP_DEBUG', true),

我们就看到了错误信息:’No supported encrypter found. The cipher and / or key length are invalid.‘。

不要着急,这是因为我们没有配置.env文件。找到laravel目录下的.env.example将其重命名.env即可。如果你是window系统,会弹出下图提示

解决方法很简单:用记事本另存,重命名即可。

现在依然不能访问,因为.env的app_key没有设置。在命令行输入:

php artisan key:generate

.env文件会自动生成app_key,偷懒的方法是随便搞一个32个字符。

 

看到’Laravel 5‘这几个大字就说明安装成功了。
