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
Or simply run below command to install by your version:
sudo apt-get install php-curl
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.
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!
$ php -S localhost:8000
in the console
;
in the php.ini file ...
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"
}
ext-curl
is already missing, how could adding it to the composer.json
resolve the problem? That doesn't magically install cURL (as Composer does not install extensions)
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).
provide
a package that is named the same as a PHP extension would also satisfy the requirements, because at the stage of comparing required and existing stuff, an extension is simply a string just like a library package name.
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.
if use wamp go to:
wamp\bin\php\php.5.x.x\php.ini
find: ;extension=php_curl.dll
remove (;)
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

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 :)
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
sudo apt-add-repository ppa:ondrej/php
does not add any package, and this won't even work when using WAMP on Windows 8 with an already enabled cURL extension
