requires ext-fileinfo. How do I add that into my composer.json file?

Question

I am trying to install intervention/image. After running the composer update, I get:

This is my composer file:

{     "name": "laravel/laravel",     "description": "The Laravel Framework.",     "keywords": ["framework", "laravel"],     "license": "MIT",     "require": {         "laravel/framework": "4.1.*",         "intervention/image": "2.*"     },     "autoload": {         "classmap": [             "app/commands",             "app/controllers",             "app/models",             "app/database/migrations",             "app/database/seeds",             "app/tests/TestCase.php"         ]     },     "scripts": {         "post-install-cmd": [             "php artisan clear-compiled",             "php artisan optimize"         ],         "post-update-cmd": [             "php artisan clear-compiled",             "php artisan optimize"         ],         "post-create-project-cmd": [             "php artisan key:generate"         ]     },     "config": {         "preferred-install": "dist"     },     "minimum-stability": "stable" } 

Answer 1

Nothing to do with your composer.json.

You need to install & enable FileInfo PHP extension, which is installed by default starting with PHP 5.3.0. Versions prior to 5.3+ may use the discontinued PECL extension.

To enable FileInfo extension, you need to edit your php.ini and change a single line.

1. Locate the line:

   ;extension=php_fileinfo.dll 

2. Remove the starting comment:

   extension=php_fileinfo.dll 

---

To find out where your php.ini is located, you can run the following command from a terminal:

$ php --ini 

and search for "Loaded Configuration File".

Please note that the PHP CLI can load a different php.ini file than the web, so don't rely on the path provided in phpinfo(). Run the command specified above in a terminal to find out the file loaded by PHP CLI.

Answer 2

We dont need to do anything in composer.json

Windows

Enable fileinfo extension in php.ini

extension= php_fileinfo.dll 

In Linux

1) Download and untar the package

wget http://pecl.php.net/get/Fileinfo-1.0.4.tgz

tar -zxf Fileinfo-1.0.4.tgz

cd Fileinfo-1.0.4

2) Generate the extension for compiling

phpize

3) Configure the module

./configure

4) generate the install files and install it

make

make install

5) Now the extension will be available under the /usr/lib64/php/modules directory. You now need to add the extension somewhere in the php configuration file. Edit /etc/php.ini and add the following: extension=fileinfo.so 6) Save the file and restart the webserver

service httpd restart

To verify fileinfo module is enabled properly, execute:

php -i | grep fileinfo

fileinfo support => enabled

Alternate method

Just an FYI, the module can also be installed using the PECL command i.e.

pecl install fileinfo

Once done, just follow steps 5 and 6 mentioned above to enable it. That’s it.
