Answer 1

You probably need to enable the extension in your php.ini file. To find out where that is for command line PHP, do

php --ini

You should see a line like

Loaded Configuration File: /path/to/php.ini

Open that file and look for extension=json.so. If it's there, uncomment it. If not, add it in. Now you should see json listed when you do php -m and composer should work.
