初投稿です。
情報不足でしたら非常に申し訳ないのですが、ご指摘頂いてもよろしいでしょうか。

aws無料利用枠でLaravel5.1の環境を構築しようとしていたところ、以下のようなエラーが出ており、困っております。

[ec2-user@ip-172-31-25-222 ~]$ composer create-project laravel/laravel:5.1 test

To enable extensions, verify that they are enabled in those .ini files:
- /etc/php.ini
- /etc/php.d/20-bz2.ini
- /etc/php.d/20-calendar.ini
- /etc/php.d/20-ctype.ini
- /etc/php.d/20-curl.ini
- /etc/php.d/20-exif.ini
- /etc/php.d/20-fileinfo.ini
- /etc/php.d/20-ftp.ini
- /etc/php.d/20-gettext.ini
- /etc/php.d/20-iconv.ini
- /etc/php.d/20-phar.ini
- /etc/php.d/20-sockets.ini
- /etc/php.d/20-tokenizer.ini
- /etc/php.d/40-json.ini
- /etc/php.d/40-zip.ini
You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.

PHPの問題だと思いますので、インストールされているPHPのversionも載せます。
[ec2-user@ip-172-31-25-222 ~]$ yum list installed | grep php
php.x86_64 5.6.18-1.el6.remi @remi-php56
php-cli.x86_64 5.6.18-1.el6.remi @remi-php56
php-common.x86_64 5.6.18-1.el6.remi @remi-php56
php-fpm.x86_64 5.6.18-1.el6.remi @remi-php56
php-pecl-jsonc.x86_64 1.3.9-1.el6.remi.5.6 @remi-php56
php-pecl-zip.x86_64 1.13.1-1.el6.remi.5.6 @remi-php56

自前でも調べて試したのですが、解決できず...
何卒よろしくお願いします。

Answer 1

php-mbstringとphp-opensslを入れたら良いと思います。

$ yum install --enablerepo=remi-php56 php-mbstring php-openssl

お返事ありがとうございます。
早速試してみましたところ、無事パッケージがダウンロードできた...と思いきや、途中でエラーを吐き出しました。

Writing lock file
Generating autoload files
> php artisan clear-compiled
PHP Fatal error: Class 'PDO' not found in /home/ec2-user/careereat/config/database.php on line 16
Script php artisan clear-compiled handling the post-install-cmd event returned with an error

database.php の16行目は以下の通りです。
'fetch' => PDO::FETCH_CLASS,

質問に質問を重ねて申し訳ありませんが、もし分かりましたら回答いただけると嬉しいです。

ではphp-pdoも入れてくださいー

$ yum install --enablerepo=remi-php56 php-pdo
