I ran into a similar issue when trying to get composer to install some dependencies. It turns out the .dll my version of Wamp came with had a conflict, I am guessing, with 64 bit Windows.

This url has fixed curl dlls: http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

Scroll down to the section that says: Fixed Curl Extensions.

I downloaded "php_curl-5.4.3-VC9-x64.zip". I just overwrote the dll inside the wamp/bin/php/php5.4.3/ext directory with the dll that was in the zip file and composer worked again.

I am running 64 bit Windows 8.

Hope this helps.

This worked for me  http   ubuntuforums org showthread php t 1519176  After installing composer using the command curl -sS https   getcomposer org installer   php just run a sudo apt-get update then reinstall curl with sudo apt-get install php5-curl  Then composer s installation process should work so you can finally run php composer phar install to get the dependencies listed in your composer json file

if use wamp go to   wamp bin php php 5 x x php ini find   extension php curl dll remove

According to https   github com composer composer issues 2119 you could extend your local composer json to state that it provides the extension  which it doesn t really do - that s why you shouldn t publicly publish your package  only use it internally

I ran into the same issue trying to install Dropbox SDK   CURL was indeed enabled on my system but this meant by the php ini in the wamp bin apache folder   I simply had to manually edit the php ini situated in wamp bin php  uncomment the extension php curl dll line  restart Wamp and it worked perfectly   Why there are those 2 php ini and only one is used is still a mystery for me     Hope it s helpul to someone

I have Archlinux with php 7 2  which has Curl integrated  so no amount of configuration voodoo would make Composer see ext-curl  that PHP could see and work with happily  Work around is to use Composer with --ignore-platform-reqs   eg composer update --ignore-platform-reqs  Reference   https   github com composer composer issues 1426

Not sure why an answer with Linux commands would get so many up votes for a Windows related question  but anyway     If phpinfo   shows Curl as enabled  yet php -m does NOT  it means that you probably have a php-cli ini too  run php -i and see which ini file loaded  If it s different  diff it and reflect and differences in the CLI ini file  Then you should be good to go   Btw download and use Git Bash instead of cmd exe

This is caused because you don t have a library php5-curl installed in your system  On Ubuntu its just simple run the line code below  in your case on Xamp take a look in Xamp documentation sudo apt-get install php5-curl  For anyone who uses php7 0 sudo apt-get install php7 0-curl  For those who uses php7 1 sudo apt-get install php7 1-curl  For those who use php7 2 sudo apt-get install php7 2-curl  For those who use php7 3 sudo apt-get install php7 3-curl  For those who use php7 4 sudo apt-get install php7 4-curl  Or simply run below command to install by your version  sudo apt-get install php-curl

As Danack said in comments  there are 2 php ini files  I uncommented the line with curl extension in the one in Apache folder  which is php ini used by the web server    Composer  on the other hand  uses php for console which is a whole different story  Php ini file for that program is not the one in Apache folder but it s in the PHP folder and I had to uncomment the line in it too  Then I ran the installation again and it was OK
