I am developing some PHP on Ubuntu 14.04.4 LS. Running composer install is failing and I can't figure it out. This was working earlier when I was using PHP 5.5.9, but I had to update to at least 5.6 in order to install phpunit.

Running php -v outputs:

PHP 5.6.23-1+deb.sury.org~trusty+2 (cli) 
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies

Running which php outputs:

/usr/bin/php

which is kind of suspicious as it doesn't match php -v (/usr/bin has: "php", "php5", and "php5.6")

Here is my composer.json:

{
    "require-dev": {
        "phpunit/phpunit": "5.4.*"
    },
    "require": {
        "silex/silex": "~1.3",
        "stripe/stripe-php": "3.*"
    }
}

Running composer install creates this output:

$ composer install
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

To enable extensions, verify that they are enabled in those .ini files:
- /etc/php/5.6/cli/php.ini
- /etc/php/5.6/cli/conf.d/10-opcache.ini
- /etc/php/5.6/cli/conf.d/10-pdo.ini
- /etc/php/5.6/cli/conf.d/20-calendar.ini
- /etc/php/5.6/cli/conf.d/20-ctype.ini
- /etc/php/5.6/cli/conf.d/20-exif.ini
- /etc/php/5.6/cli/conf.d/20-fileinfo.ini
- /etc/php/5.6/cli/conf.d/20-ftp.ini
- /etc/php/5.6/cli/conf.d/20-gettext.ini
- /etc/php/5.6/cli/conf.d/20-iconv.ini
- /etc/php/5.6/cli/conf.d/20-json.ini
- /etc/php/5.6/cli/conf.d/20-phar.ini
- /etc/php/5.6/cli/conf.d/20-posix.ini
- /etc/php/5.6/cli/conf.d/20-readline.ini
- /etc/php/5.6/cli/conf.d/20-shmop.ini
- /etc/php/5.6/cli/conf.d/20-sockets.ini
- /etc/php/5.6/cli/conf.d/20-sysvmsg.ini
- /etc/php/5.6/cli/conf.d/20-sysvsem.ini
- /etc/php/5.6/cli/conf.d/20-sysvshm.ini
- /etc/php/5.6/cli/conf.d/20-tokenizer.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

I followed these instructions but it doesnt work: Composer install error - requires ext_curl when it's actually enabled

Running php -i | grep php.ini outputs:

Configuration File (php.ini) Path => /etc/php/5.6/cli
Loaded Configuration File => /etc/php/5.6/cli/php.ini

Running: sudo apt-get install php5-curl outputs:

php5-curl is already the newest version.

Running curl -V outputs:

curl 7.35.0 (x86_64-pc-linux-gnu) libcurl/7.35.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 librtmp/2.3
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtmp rtsp smtp smtps telnet tftp 
Features: AsynchDNS GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP

Any help is appreciated.

Some notes:

  • Running php -i is good. It shows you the php.ini used, so that you know which file to edit.
  • Running curl -v is not needed, because that's the standalone curl for usage on the CLI and unrelated to the PHP Extension curl.
  • You checked for php5-curl, that's the needed package. Ok.

What's missing? You need to make sure the extension is also loaded by PHP!

Edit your /etc/php/5.6/cli/php.ini, search for extension, look for php_curl and enable it: extension=php_curl.so.

Then run php -m on the CLI to see the list of loaded modules and ensure that curl is loaded.

Finally, re-run your composer install.

Thank you for the response. The php.ini file does not have a php_curl.so -- it has php_curl.dll, but that's for windows and I'm on Ubuntu. Enabling this line did not work. The file only has two .so mentions, both for mysql. I got the "extensions_dir" from phpinfo(), and there is a "curl.so" in that directory. I followed the instructions from here as well: stackoverflow.com/questions/23233460/… and the file /etc/php5/mods-available/curl.ini does exist, and it does have "extension=curl.so" in it. Updating question above.
Right, when on Linux/Ubuntu you need to enable the .so file. I wonder why enabling that didn't work, when you already found the php_curl.so file in the extension folder. Please check with php -m, if it is loaded. -- If it is not loaded, i think you are still editing the wrong php.ini for the PHP you are using on the CLI. Keep in mind that there a differnt php.ini files - for web requests and for the CLI.
php -m does not list curl. The command php -i | grep php.ini makes me think I am editing the proper php.ini file. In that php.ini file I added extension=/path/to/extensions/curl.so (got the path from the output of phpinfo()) and now php -m lists curl. Now when I run composer install I am getting an error about another missing package (ext-mbstring), so that seems to work.
But the fact that I keep getting errors makes me think something is wrong. Typing dpkg -l | grep 'php5-curl' outputs: ii php5-curl 5.6.23+dfsg-1+deprecated+dontuse+deb.sury.org~trusty+1 amd64 CURL module for php5. Notice it has "deprecated+dontuse" in there. When upgrading my PHP version, it did not go smoothly, I saw this "deprecated" message and did another upgrade to a higher version. Perhaps I will uninstall all PHP and start again.
Glad it worked out. | Well, if the curl extension is properly loaded and you don't get an API conflict between PHP extension and PHP core displayed, when you run PHP, then it simply works - even if it is flagged as deprecated. | If you get an API mismatch, then reinstalling PHP with extensions might clear the situation.
