[chuhemiao]

1.错误如下： 2016/03/30 13:51:18 [error] 19169#0: *193 FastCGI sent in stderr: "PHP message: PHP Warning: require(/var/www/baqiye/bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in /var/www/baqiye/bootstrap/autoload.php on line 17PHP message: PHP Fatal error: require(): Failed opening required '/var/www/baqiye/bootstrap/../vendor/autoload.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/baqiye/bootstrap/autoload.php on line 17" while reading response header from upstream, client: 106.2.166.202, server: baqiye.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "www.baqiye.com" 2.查看 /var/www/baqiye/bootstrap/../vendor/autoload.php,这里没有 autoload.php 这个文件，是引入错误了吗？还是其它的什么情况 3.用 composer 安装的 laravel 、服务器 centos6.5 ， php 环境 5.6.18 ， nginx1.8.1

[chenset]

composer install
composer update
composer dump-autoload

执行后再看看

[aaronly]

php artisan clear-compiled
php artisan optmize

[run2]

呃，这么基础的东西 可以先 bing Google 么 谢谢 怪不得社区里面歧视 PHP 群体
看到 vendor/autoload.php 不可能搜不出 composer 相关消息

[chuhemiao]

@chenset 执行了，出现这个 https://segmentfault.com/q/1010000004734238
@aaronly 执行没反应啊
@sobigfish 好忧伤。。。。

试试看国内镜像
