从 Megento 2.0.2 升级失败 "An error has happened during application run. See exception log for details."

Question

使用 Bitnami 堆栈的 CentOS 上的 Magento 2.0.2。使用 Composer 进行命令行升级。

尝试在升级后加载店面（按照没有错误的步骤）导致上述错误。 /var/log/exception.log 文件显示：-

[2016-06-09 15:18:04] main.CRITICAL: exception 'Magento\Framework\Exception\LocalizedException' with message 'Source class "" for "Magento\Framework\App\Response\Http\Interceptor" generation does not exist.' in /opt/bitnami/apps/magento/htdocs/lib/internal/Magento/Framework/Code/Generator.php:171

10 {main} [] []
}

已检查权限并手动清除 var/cache，但无济于事。

有什么办法可以解决这个错误吗？

Answer 1

这应该有帮助：

cd <your magento root>
rm -Rf var/generation/* var/di/*
bin/magento cache:clean

Answer 2

对于 ubuntu： 1) 转到 var/www/html/magento（你的 magento 所在的根文件夹）或者如果你已经安装了 lampp，则在 htdocs 中。 2) 须藤 rm -Rf var/generation 3) 须藤 bin/magento cache:clean 4)须藤bin/magentocache:flush

完成.....
