我正在使用 homestead 环境，命令行“php artisan -V”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):

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

还有..甚至是我在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

最佳答案

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

此问题的解决方案是插入本应存在的代码 (found in bootstrap/autoload.php here)。

文件最终丢失的原因尚不清楚。
