php -v

ERROR:

Old question, but I stumbled upon the same error.

You might be missing igbinary

Install it with:

apt-get install php-igbinary

(You may need to use php7.X-igbinary, depending on your version)

My installation was also missing msgpack, which I installed as well:

apt-get install php-msgpack
