Question

我是laravel框架甚至网站开发的绝对初学者。

我的PHP版本是5.6。我在我的Amazon Linux服务器上安装laravel框架时遇到了麻烦。

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
- /etc/php-5.6.d/20-posix.ini
- /etc/php-5.6.d/20-shmop.ini
- /etc/php-5.6.d/20-simplexml.ini
- /etc/php-5.6.d/20-sockets.ini
- /etc/php-5.6.d/20-sysvmsg.ini
- /etc/php-5.6.d/20-sysvsem.ini
- /etc/php-5.6.d/20-sysvshm.ini
- /etc/php-5.6.d/20-tokenizer.ini
- /etc/php-5.6.d/20-xml.ini
- /etc/php-5.6.d/20-xmlwriter.ini
- /etc/php-5.6.d/20-xsl.ini
- /etc/php-5.6.d/20-zip.ini
- /etc/php-5.6.d/30-wddx.ini
- /etc/php-5.6.d/30-xmlreader.ini
- /etc/php-5.6.d/40-json.ini
- /etc/php-5.6.d/php.ini
 You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

经过多次研究，似乎我必须取消注释行“extension = php.mbstring.dll 。所以我试图找到它，但我的php.ini文件AWS服务器甚至没有该行。然后我自己放线，但现在我必须处理不同的错误。

我不知道该怎么做了。以前有没有人遇到类似这样的问题？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您需要更多信息，请告诉我！

任何建议将不胜感激！提前谢谢！

Answer 1

你需要PHP exstion 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

Answer 2

如上所述，唯一的问题是您还没有在Linux机器上启用mbstring扩展。由于您已经安装了php5.6，因此您需要执行以下命令：

sudo apt-get install php5.6-mbstring - ＆gt;安装php5.6的mbstring扩展 systemctl restart apache2或sudo service apache2 restart - ＆gt;重新启动服务器以应用更改

那应该解决它。

LARAVEL安装：“PHP.INI”中没有“EXTENSION = PHP_MBSTRING.DLL”
