Problem ~ Composer Install

Setelah memasang ulang sisop pada laptop yang saya gunakan, waktunya oprak oprek lagi.

Ceritanya mau masang alat konversi data hasil olahannya Ido Alit yang bisa dilihat di sini:

https://github.com/idoalit/converter

Alat pengkonversi ini menggunakan alat yang dibuat oleh Hendro Wicaksono yaitu, Persneling:

https://github.com/hendrowicaksono/persneling

Nah, paket aplikasi yang diperlukan untuk menjalan aplikasi konversi di atas adalah composer. Karena komponen yang harus dijalankan pertama kali setelah klon data adalah:

$ composer install

Pada sisop yang saya gunakan, ternyata ada masalah yang terjadi yaitu:

"...the requested PHP extension dom is missing from your system."

Lengkapnya begini:

buitenzorg812@theminion:/var/www/html/converter$ composer install

  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
    - /etc/php/5.6/cli/conf.d/10-pdo.ini

    - /etc/php/5.6/cli/conf.d/20-sysvshm.ini
    - /etc/php/5.6/cli/conf.d/20-tokenizer.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Panjang khan? Iya. Lantas solusinya adalah, dengan memasang paket ini:

  • php5.6-xml; atau
  • php7.0-xml
Silahkan disesuaikan dengan versi php yang digunakan. Karena saya menggunakan PHP 5.6, maka saya memasang yang versi php5.6.

Udah, gitu ajah ;).
