【问题描述】：

我正在使用宅基地环境和命令行“php artisan -V”它不起作用。我用“laravel new test”创建了我的项目，所以..我想我的所有文件都已更新。

vagrant@homestead:~/Laracasts/test$ php artisan -V
PHP Warning:  require(/home/vagrant/Laracasts/test/bootstrap/autoload.php):         
failed to open stream: No such file or directory in         
/home/vagrant/Laracasts/test/artisan on line 16

Warning: require(/home/vagrant/Laracasts/test/bootstrap/autoload.php):     
failed to open stream: No such file or directory in 
/home/vagrant/Laracasts/test/artisan on line 16
PHP Fatal error:  require(): Failed opening required 
'/home/vagrant/Laracasts/test/bootstrap/autoload.php' 
(include_path='.:/usr/share/php') in /home/vagrant/Laracasts/test/artisan on 
line 16

vagrant@homestead:~/Laracasts/test$

.yaml 文件

ip: "192.168.10.10"
memory: 2048
cpus: 1
provider: virtualbox

authorize: ~/.ssh/id_rsa.pub

keys:
- ~/.ssh/id_rsa

folders:
- map: ~/Desktop/Arnau/dev/repositories/phpmyadmin
  to: /home/vagrant/phpmyadmin

- map: ~/Desktop/Arnau/dev/repositories/Laravel
  to: /home/vagrant/Laravel

- map: ~/Desktop/Arnau/dev/repositories/Laracasts
  to: /home/vagrant/Laracasts

sites:
- map: phpmyadmin.app
  to: /home/vagrant/phpmyadmin

- map: administracio.dev
  to: /home/vagrant/Laravel/administracio/public

- map: laracasts.dev
  to: /home/vagrant/Laravel/laracasts/public

databases:
- phpmyadmin
- administracio
- laracasts

而且.. 甚至我最后添加的主机文件。

192.168.10.10 administracio.dev
192.168.10.10 laracasts.dev

php composer.phar 安装后的下一个错误

vagrant@homestead:~/Laracasts/test$ php composer.phar install

【问题讨论】：

你也可以发布你的 homestead.yaml 文件吗？
我添加了更多信息
尝试在测试项目的根目录下运行 composer install。我猜作曲家还没有编译自动加载器。
我使用了在这里找到的命令行安装：getcomposer.org/download 使用 Composer 下载的所有设置都正确... Composer（1.4.1 版）已成功安装到：/home/vagrant/Laracasts /test/composer.phar 使用它： php composer.phar vagrant@homestead:~/Laracasts/test$ php -r "unlink('composer-setup.php');" vagrant@homestead:~/Laracasts/test$ 但还是一样的错误。
你有运行作曲家吗？进入php composer.phar install 类型的目录，看看是否有帮助。

【解决方案1】：

经过长时间的讨论和调试，问题变得清晰了； bootstrap/autoload.php 文件丢失。

解决此问题的方法是插入本应存在的代码 (found in bootstrap/autoload.php here)。

但文件丢失的原因尚不清楚。
