我是laravel框架甚至web开发的绝对初学者。
我的PHP版本是5.6。我在AmazonLinux服务器上安装laravel框架时遇到问题。
以下是我遇到的第一个错误。

To enable extensions, verify that they are enabled in those .ini files:
- /etc/php.ini
- /etc/php-5.6.d/20-bz2.ini
- /etc/php-5.6.d/20-calendar.ini
- /etc/php-5.6.d/20-ctype.ini
- /etc/php-5.6.d/20-curl.ini
- /etc/php-5.6.d/20-dom.ini
- /etc/php-5.6.d/20-exif.ini
- /etc/php-5.6.d/20-fileinfo.ini
- /etc/php-5.6.d/20-ftp.ini
- /etc/php-5.6.d/20-gettext.ini
- /etc/php-5.6.d/20-iconv.ini
- /etc/php-5.6.d/20-phar.ini

You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
经过几次研究，我似乎不得不取消对"extension=php.mbstring.dll这一行的注释。所以我试图找到它，但我的AWS服务器中的php.ini文件中甚至没有这一行。然后我自己放了这一行，但现在我必须处理另一个错误。
我不知道该怎么办了。以前有人遇到过类似的问题吗？如果你有，你能帮我解决这个问题吗？
我的英语不是我的第一语言，所以如果这篇文章没有意义，或者你需要更多信息，也请告诉我！
任何建议都将不胜感激！提前感谢！
您需要PHP exsion mbstring。
//if your using ubuntu or debian
sudo apt-get install libapache2-mod-php5
//or if your using centos this should install it
yum install php
如上所述，唯一的问题是您没有在linux机器中启用mbstring扩展。由于您已经安装了php5.6，因此需要运行以下命令：
sudo apt-get install php5.6-mbstring->安装php5.6的mbstring扩展systemctl restart apache2或sudo service apache2 restart->重新启动服务器以应用更改
这应该可以解决问题。
