无法安装Laravel Package - 干预图像

Question

So I am following the tutorial on tuts+ Premium from Jeffrey Way - Creating an Ecommerce App in Laravel 4 and I am stuck with this problem. He is installing a package by just editing the composer.json file with this line "intervention/image": "dev-master" and then just types 'composer update' into his console. I try the same but it won't work.

It displays this error

" Problem 1 - intervention/image 2.0.2 requires ext-fileinfo * -> the requested PHP exte nsion fileinfo is missing from your system. - intervention/image 2.0.1 requires ext-fileinfo * -> the requested PHP exte nsion fileinfo is missing from your system. - intervention/image 2.0.0 requires ext-fileinfo * -> the requested PHP exte nsion fileinfo is missing from your system. - Installation request for intervention/image 2.* -> satisfiable by interven tion/image[2.0.0, 2.0.1, 2.0.2]."

I have tried following their instructions on http://image.intervention.io/getting_started/installation but it wouldn't work.

I don't know how to handle this issue. Please help. I also read somewhere that I should edit the php.ini file and uncomment a line for fileinfo but after restarting Apache again it did not work.

I am using Windows 8 with wamp and Laravel.

Any help would be appreciated greatly.

Answer 1

Make sure that, you have php_fileinfo.dll is installed/available in your php\ext folder and also make sure that, the following line is not commented in php.ini file:

extension=php_fileinfo.dll

If it's commented like this:

;extension=php_fileinfo.dll

Then just remove that ; from the beginning of the line and then restart the wamp/apache server.

Update:

However, some web servers are confusing because they do not use the php.ini located alongside your PHP executable. To find out where your actual php.ini resides, look for its path in phpinfo():

After activating an extension, save php.ini, restart the web server and check phpinfo() again. The new extension should now have its own section.
