[FIXED] The composer does not see php-curl

Issue

Good afternoon at installation drupal 8 by use composer screenshot. I get the following dependency error. screenshot error

On my local machine installation was successful and without a problem. But I do not want to work on the server. At what on another user, the co-op is working like normal.

As far as I understood, he asks for the installation of a php-curl. But he is clever. I was eating to reset the php-curl and php-cli and restart the server and also run from the user root but nothing helped.

  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Solution

I corrected this problem as follows. 1) Found the extension Curl file

ls /usr/lib/php/20151012/ | grep curl
- result:
curl.so

2) Change path in /etc/php/7.0/cli/php.ini

extension=php_curl.dll --> change on
extension=curl.so
