基本上，我在Windows 10机器中使用基本模板开发yii2没有问题。但是现在，我继续将这个 yii2 应用程序开发到 ubuntu 16.04 中
。我把yii_folder放到/var/www/html/yii_basic 中，然后访问它本地主机/yii_basic/网络，可悲的是它查看了一个空白页面。
我不知道检查 .htaccess 在yii_basic/Web 文件夹中没有问题，也启用mod_rewrite。
然后我尝试由作曲家检查，
它给了我：
Problem 1

To enable extensions, verify that they are enabled in those .ini files:
- /etc/php/5.6/cli/php.ini
- /etc/php/5.6/cli/conf.d/10-mysqlnd.ini
- /etc/php/5.6/cli/conf.d/10-opcache.ini

请告诉我我应该这样做。
显然安装缺少的PHP扩展。
sudo apt-get install php5.6-xml
尝试在
索引中使用此代码进行调试.php
ini_set('error_reporting', E_ERROR);
register_shutdown_function("fatal_handler");
function fatal_handler() {
$error = error_get_last();
echo("<pre>");
print_r($error);
}
您的 php 扩展未安装或配置。
