Composer installing: the json extension is missing
Solution 1
I encountered the same error, but the difference was that when I ran php -m
the json
module was not listed, so I just installed json PHP module using the command below:
sudo yum install php-json
the error was fixed and I was able to install composer. I was using CentOS 8 stream, PHP7.2.
Solution 2
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.
Solution 3
Bug php not load extension install
create file php.ini
# /etc/php/7.2/cli/conf.d/php.ini
extension=json.so
extension=phar.so
extension=iconv.so

I wrote in Linux Terminal:
curl -s https://getcomposer.org/installer | php
It said:#!/usr/bin/env php 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
I did this:
apt-get install php5-json
So, I think, it's installed. But the strange thing is, when I writephp -m
It gives me a list without json:[PHP Modules] bcmath bz2 calendar Core ctype date dba dom ereg exif fileinfo filter ftp gettext hash iconv libxml mbstring mhash openssl pcntl pcre Phar posix Reflection session shmop SimpleXML soap sockets SPL standard sysvmsg sysvsem sysvshm tokenizer wddx xml xmlreader xmlwriter zip zlib [Zend Modules]
And when I write
php5-fpm -m
It sends this:[PHP Modules] bcmath bz2 calendar cgi-fcgi Core ctype curl date dba dom ereg exif fileinfo filter ftp gettext hash iconv json libxml mbstring mcrypt mhash mysqli openssl pcre PDO pdo_mysql Phar posix Reflection session shmop SimpleXML soap sockets SPL standard sysvmsg sysvsem sysvshm tokenizer wddx xml xmlreader xmlwriter zip zlib [Zend Modules]
What am I doing wrong? I haven't found the solution at GitHub and Google
