在laravel 4中找不到“图像”类

Question

I downloaded a website developed on laravel4 on my system and runing it on my localhost . Some of the pages are not working .

When I am trying to upload an Image . following error is occurring.

Symfony \ Component \ Debug \ Exception \ FatalErrorException (E_UNKNOWN)
HELP
Class 'Image' not found

So I googled and got to know that I will have to add the intervention/image in my coomposer.json file i changed the code of json array from

"require": {
        "laravel/framework": "4.2.*",
        "intervention/image": "1*"
    },

to

"require": {
        "laravel/framework": "4.2.*",
        "intervention/image": ""2.3.0""
    },

Then I did composer update and I am getting following error

Any leads ??

C:\Users\User\Desktop\ideconnect>composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for intervention/image 2.3.0 -> satisfiable by interv
ention/image[2.3.0].
    - intervention/image 2.3.0 requires ext-fileinfo * -> the requested PHP exte
nsion fileinfo is missing from your system.

Thanks

The error you're getting is fairly clear:

the requested PHP extension fileinfo is missing from your system.

This means that the package you are trying to install relies on a PHP extension that your specific PHP installation does not have. This is fixable, but might be specific to your environment.

The first thing to do would be to check your php.ini and see if the extension is simply commented out. If you are using Windows, it might look like this inside php.ini:

;extension=php_fileinfo.dll

you should uncomment it like so:

extension=php_fileinfo.dll

After doing this you will need to restart your webserver.

If that doesn't work, you will need to look for more info in the PHP manual: http://php.net/manual/en/fileinfo.installation.php
