Composer install error - requires ext_curl when it's actually enabled

I'm trying to install Facebook PHP SDK with Composer. This is what I get

$ composer install
Loading composer repositories with package information
Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages. Problem 1 - Installation request for facebook/php-sdk dev-master -> satisfiable by facebook/php-sdk[dev-master]. - facebook/php-sdk dev-master requires ext-curl * -> the requested PHP extension curl is missing from your system.

Problem is, I have curl extension enabled (uncommented in php.ini). When I run phpinfo(), it says it's enabled. Only clue I have is that when I run $ php -m, 'curl' line is missing but I don't know what to do about it.

I have wamp 2.4 on Win8 and I'm running composer in 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

For those who use php8.0

sudo apt-get install php8.0-curl

For those who use php8.1

sudo apt-get install php8.1-curl

Or simply run below command to install by your version:

sudo apt-get install php-curl

This worked for me:

After installing composer using the command curl -sS | 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.

on php7 run for example:

> sudo apt-get install php-curl
> sudo apt-get install php-mbstring

for every missing extension. Then:

> sudo apt-get update

and finally (in the project's root folder):

> composer install

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.

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 had this problem after upgrading to PHP5.6. My answer is very similar to Adriano's, except I had to run:

sudo apt-get install php5.6-curl

Notice the "5.6". Installing php5-curl didn't work for me.

For anyone who encounters this issue on Windows i couldn't find my answer on google at all. I just tried running composer require ext-curl and this worked. Alternatively add the following in your composer.json file:

"require": {
"ext-curl": "^7.3"
}

According to 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 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:

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.

if use wamp go to:

wamp\bin\php\php.5.x.x\php.inifind:;extension=php_curl.dllremove (;)

Enable in php 7 try below command

sudo apt-get install php7.0-curl

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!

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 =

try install php5-curl by using below snippet.

sudo apt-get install php5-curl

if it won't work try below code i m sure it will work fine.

sudo apt-get install php-curl

for me it worked... all the best :)

If you are ubuntu, this will work for you.

composer update --ignore-platform-reqs

for ubuntu 20.* this will work.

sudo apt-get install php-curl

In my case I moved from PHP5 to PHP7 and I ve got this error, Simply go to your /bin/php/php7/php.ini , then uncomment extension=php_curl.dll and restart your server, re-run your composer install.

If you getting error like php7.2-curl doesn't have installable candidate or not locate any package or dependencies is php7.2-common Or libcurl3 Do this

You have to tackle in mature way. Install aptitude these ubuntu package manager will finds all dependencies, and will install one by one.

apt-get install aptitude

Now you have to check if aptitude can download it or not if download it follow instructions

sudo aptitude install php7.2-curl

If you have gotten any error like this

E: Unable to locate package php7.2-curl
E: Couldn't find any package by glob 'php7.2-curl'

Any type on error i'm not talking about proper these errors

Try to add php package again

sudo apt-add-repository ppa:ondrej/php
sudo apt-get update

Now try this command

sudo aptitude install php7.2-curl

Aptitude will ask you you want to keep current version of all dependencies

The following actions will resolve these dependencies: Keep the following packages at their current version:
1) php7.2-curl [Not Installed]
Accept this solution? [Y/n/q/?]

Type n then Enter

Aptitude will find all dependencies and ask you to install all package type

y

Again

y

Then

systemctl restart apache2

For centos of rhel

systemctl restart httpd

It will Not enabling PHP 7.2 FPM by default. NOTICE: To enable PHP 7.2 FPM in Apache2 do

a2enmod proxy_fcgi setenvif
a2enconf php7.2-fpm

This method is not only for this error you can find any of php apache2 or ubuntu system package solution using aptitude.

Upvote if you find your solution

If you have any version of php installed on your OS, you just have to install: sudo apt-get install php-curl

The system configures the rest in your available PHP version.
