I've recently tried to install package through Composer, but I have got an error the requested PHP extension mbstring is missing from your system. I removed semicolon from php.ini, but it still doesn't work. What should I do?

I have it in php /ext directory.

@joci, see this answer.

What OS are you using (linux/mac/windows)? What webserver are you using (iis/nginx/apache/etc)? Have you restarted the webserver software since updating the php.ini file?

I'm using Windows with apache server(MAMP). Yes, I restarted server.

mbstring settings uncommented in php.ini?

sudo apt-get install php-mbstring

# if your are using php 7.1
sudo apt-get install php7.1-mbstring

# if your are using php 7.2
sudo apt-get install php7.2-mbstring

# if your are using php 7.4
sudo apt-get install php7.4-mbstring

This worked but I had to install the specific php version: sudo apt-get install php5.6-mbstring. Do a search with apt-cache search mbstring to see which versions are available for your system.

also apt-get install php7.1-mbstring works for me

If running this returns an error of Unable to locate package php-mbstring, try running sudo apt-get update first.

And of course, apt-get install php7.2-mbstring

confirmed working (sudo apt-get install php7.2-mbstring) on ubuntu php 7.2.24

find your php.ini make sure the directive extension_dir=C:\path\to\server\php\ext is set and adjust the path (set your PHP extension dir) make sure the directive extension=php_mbstring.dll is set (uncommented)

If this doesn't work and the php_mbstring.dll file is missing, then the PHP installation of this stack is simply broken.

I reinstalled server, but nothing has changed.

That's odd. Maybe ask for support over at MAMP or simply switch the stack.. XAMPP, WPN-XM.

I finally solved it. I set PHPRC variable and uncommented zend_extension=php_opcache.dll in php.ini.

And also I installed C++ redistributable and directx. I don't know where was a problem, but it works perfect now.

In my case there was no line for the extension php_mbstring in php.ini file. So I installed it using sudo apt-get install php7.3-mbstring. My php version is 7.3 and it worked like charm.

For php 7.1

sudo apt-get install php7.1-mbstring

Cheers!

this do not work for me, which repo are you using?

On Ubuntu 18 it worked as above.

cchapman

I set the PHPRC variable and uncommented zend_extension=php_opcache.dll in php.ini and all works well.

Can you explain better what you did please?
