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

Question

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.

Answer 1

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

Or simply run below command to install by your version:

sudo apt-get install php-curl

Answer 2

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.

Answer 3

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.

Answer 7

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"
}

Answer 8

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).

Answer 9

Enable in php 7 try below command

sudo apt-get install php7.0-curl

Answer 10

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.

Answer 11

if use wamp go to:

wamp\bin\php\php.5.x.x\php.ini find: ;extension=php_curl.dll remove (;)

Answer 12

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

Answer 13

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 :)

Answer 14

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!

Answer 15

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.
