I am getting an error when trying to install the squizlabs/php_codesniffer package via composer into my WordPress plugin.

I am using Flywheel for the local server, with composer 1.8.6 installed globally at /usr/local/bin/composer.phar

I have also tried using the composer file locally in the plugin folder, but I still get the same error. This is the command I run while in the plugin directory

composer require --dev squizlabs/php_codesniffer

• Should this question rather be on the main stack overflow site? or is it fine here? – Warwick Commented Jun 28, 2019 at 8:15
• Yes, better on Stack Overflow. – norman.lol Commented Jun 28, 2019 at 8:16
• Also better put the error message in a blockquote. Screenshots are a pain to read. Especially on mobile. – norman.lol Commented Jun 28, 2019 at 8:18
• 1 @Warwick I guess you need to update OpenSSL. – Sally CJ Commented Jun 28, 2019 at 8:19

I managed to fix the error by updating openssl as @Sally Cj said. I was still using Mac OS El Capitan, so I tried the Homebrew method of updating it, but that didnt fix it.

I eventually ended up just upgrading to the latest "Mojave" OS version, and it works 100% now.
