Composer install failed
Solution 1
I solved the issue by downloading https://curl.haxx.se/ca/cacert.pem and giving it's path in my etc/php/5.6/cli/php.ini
and etc/php/5.6/apache2/php.ini
.
Then after running sudo service apache2 restart && sudo apt install composer
just worked fine.
Solution 2
Open terminal and run php -r "var_dump(openssl_get_cert_locations());"
Note the location of default_cert_file
. It might say \usr\local\ssl\cert.pem
Verify that that file exists. If not, download the cacert.pem file from https://curl.haxx.se/ca/cacert.pem and place it in somewhere preferably in /usr/local/ssl
You now have a file is usr/local/ssl/cacert.pem
Open your php.ini and add the location of the file openssl.cafile=cacert.pem
Install composer
Run composer config --global cafile "/usr/local/ssl/cacert.pem"
Solution 3
It looks like a misconfiguration of PHP/openssl on your host.
My workstation is Ubuntu 16.04.3, php 7.0.22 and openssl-1.0.2g - the installer worked fine.
Try with TLS disabled:
curl -sS https://getcomposer.org/installer | php -- --disable-tls
Solution 4
I experienced this problem while using Laravel Homestead after I’d accidentally emptied the contents of this file: /etc/ssl/certs/ca-certificates.crt
What fixed it for me was:
sudo apt-get purge ca-certificates
sudo apt-get install ca-certificates

.I used:
curl -sS https://getcomposer.org/installer | php
. But it is giving me error as follows:All settings correct for using Composer Downloading...

I do not have composer installed previously.
