Magento – problem when create a language package for Magento 2

languagemagento-enterprisemagento2theme

I try to create Arabic language package for Magento 2

I follow this tutorial

https://mage2.pro/t/topic/270

I did the following command to create language dictionary

./magento i18n:collect-phrases -o "/var/www/html/magento/app/i18n/AlMouje/ar_SA/dictionary.csv" -m "/var/www/html/magento/"

and this is app folder tree 

└── i18n
    └── almouje
        └── ar_SA
            ├── composer.json
            ├── dictionary.csv
            ├── language.xml
            └── registration.php

and this is the composer.json file 

{
    "name": "almouje/language-ar_sa",
    "description": "Arabic (Saudi Arabia) language",
    "version": "100.0.2",
    "license": [
        "OSL-3.0",
        "AFL-3.0"
    ],
    "require": {
        "magento/framework": "100.0.*"
    },
    "type": "magento2-language",
    "autoload": {
        "files": [
            "registration.php"
        ]
    }
}

and this is the language.xml file 

<?xml version="1.0"?>
<!--
/**
 * Copyright © 2015 Magento. All rights reserved.
 * See COPYING.txt for license details.
 */
-->
<language xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/Language/package.xsd">
    <code>ar_SA</code>
    <vendor>almouje</vendor>
    <package>ar_sa</package>
</language>

and this is registration.php file 

<?php
/**
 * Copyright © 2015 Magento. All rights reserved.
 * See COPYING.txt for license details.
 */

\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::LANGUAGE,
    'almouje_ar_sa',
    __DIR__
);

and when I try to load the home page I get this error

Best Answer

for some reason, your csv file seems to be not valid.

The error output relates to this line: https://github.com/magento/magento2/blob/develop/lib/internal/Magento/Framework/App/Language/Dictionary.php#L183

Each csv row must have at least 2 columns: 

"Original String","Translated String"

(Ok I bet you know that)

So you should check the csv File. You could also debug at the given Codeline and try to find out, on which line (in the csv file) this error occurs

===UPDATE===

It may also be an encoding Problem. Also, Microsoft Excel for Example almost always broke my csv Files somehow, often just by opening them. I would recommend to use Openoffice or Libreoffice Calc for editing csv files
