I’m trying to install composer on my Ubuntu 13.10 machine but the following error occurs:
Some settings on your machine make Composer unable to work properly. Make sure that you fix the issues listed below and run this script again: The json extension is missing. Install it or recompile php without --disable-json
php --version gives me
PHP 5.5.3-1ubuntu2 (cli) so I think it should have the json extension installed.
just install the module:
sudo apt-get install php5-json
EDIT – Reason:
See Heanzo Beanzo Comment:
It has been removed in recent packages due to a license conflict see
bug on php.net.
