'Composer installing: the json extension is missing

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 write php -m It gives me a list without json:

And when I write php5-fpm -m It sends this:

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.

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.

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

On ubuntu 14.04 for me, I found that the default permissions for the php.ini file /etc/php5/cli/ restrict the file to Root user only, so if you run:

php -m

as non-root, you get far fewer modules than if you run sudo php -m

The fix for this was for me to perform:

sudo chmod a+rx /etc/php5/cli/* -R

which grants read and execute permissions for that folder and it's contents to everyone.

On Centos 8 with PHP 7.2, after comprehensive research, I have concluded that the only solid way to fix it is reinstalling PHP with its newest version. (7.4 was the latest version for me) Here you can find others who share the same conclusion; laracasts

Solution 6:[6]

you can use the :-

sudo apt-get install php-json

command. and correct the directory. so your error will resolved.
