I want to install composer for using laravel in Ubuntu 17.10, when I tried it gives me error.
I tried those methods;
- https://getcomposer.org/download/
- https://www.digitalocean.com/community/tutorials/how-to-install-and-use-composer-on-ubuntu-16-04 (I know it's for old version
Errors;
$ php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
PHP Warning: copy(): SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed in Command line code on line 1
PHP Warning: copy(): Failed to enable crypto in Command line code on line 1
PHP Warning: copy(https://getcomposer.org/installer): failed to open stream: operation failed in Command line code on line 1
And:
$ php -r "if (hash_file('SHA384', 'composer-setup.php') === '669656bab3166a7aff8a7506b8cb2d1c292f042046c5a994c43155c0be6190fa0355160742ab2e1c88d40d5be660b410') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
Installer corrupt
What I need to do ?
