Fatal error: Uncaught ReflectionException: Class log does not exist in /home/liuman/jlcloud2/vendor/laravel/framework/src/Illuminate/Container/Container.php:736 Stack trace: #0 /home/liuman/jlcloud2/vendor/laravel/framework/src/Illuminate/Container/Container.php(736): ReflectionClass->__construct(‘log’) #1 /home/liuman/jlcloud2/vendor/laravel/framework/src/Illuminate/Container/Container.php(626): Illuminate\Container\Container->build(‘log’, Array) #2 /home/liuman/jlcloud2/vendor/laravel/framework/src/Illuminate/Foundation/Application.php(674): Illuminate\Container\Container->make(‘log’, Array) #3 /home/liuman/jlcloud2/vendor/laravel/framework/src/Illuminate/Container/Container.php(837): Illuminate\Foundation\Application->make(‘log’) #4 /home/liuman/jlcloud2/vendor/laravel/framework/src/Illuminate/Container/Container.php(800): Illuminate\Container\Container->resolveClass(Object(ReflectionParameter)) #5 /home/liuman/jlcloud2/vendor/laravel/framework/src/Illuminate/Container/Container.php(769): Illuminate\Container\Container in /home/liuman/jlcloud2/vendor/laravel/framework/src/Illuminate/Container/Container.php on line 736

解决方案：

删除vendor文件夹和composer.lock

composer install

laravel 500错误是storage没有权限

解决方案：chmod -R 777 storage

cache错误

file_put_contents(/..cache/services.json): failed to open stream: Permission denied

解决方案：sudo php artisan cache:clear

php composer.phar install报错

先安装composer，然后运行php composer.phar install –no-scripts

PDO错误，已安装PDO还提示

[PDOException]
SQLSTATE[HY000] [2002] No such file or directory

解决方案：将.env下的DB_HOST＝localhost改为DB_HOST＝127.0.0.1

SQLSTATE[HY000] [1045]

解决方案：
php artisan cache:clear
php artisan config:clear

php artisan 没反应

composer dumpautoload
