php - Install third party library using composer

Question

Centos6.8
PHP version

1. Use composer to install a third-party library, and an error message appears: SHA384 is not supported by your openssl extension

2. When installing directly, an error will be reported: Segmentation fault

The original poster doesn’t understand composer very well. What’s going on?

Answer 1

mv composer.phar /usr/local/bin/composer

Then execute composer to see if the installation is successful

Answer 2

1. First check whether openssl expansion is enabled

2. If it is enabled, it means that your openssl version is too low. Upgrade your php. I also encountered this last time and directly installed php5.6. Problem solved
