- Installation request for facade/flare-client-php 1.3.2 -> satisfiable by facade/flare-client-php[1.3.2].
But mbstring is already installed in php72. First I check the version of the php --v and it returned
PHP 7.2.24
then checked the loaded modules php72 -m and there was mbstring no problem there too... After that I checked the mbstring is enabled or not php72 -i | grep mbstring and it's enabled
Multibyte decoding support using mbstring => enabled
In the end why composer is not seeing the mbstring? I check the modules of composer show -p seeing. And NO there is no mbstring! Any idea why composer not seeing the mbstring and how can I fix this issue?
Additionally I am in Centos 7
Your mbstring extension is missing for php7.2
Run sudo apt-get install -y php7.2-mbstring
Edit
Also, mockery/mockery 1.4.0 requires php ^7.3.0.
I suggest upgrading your project php version.
Log speaks for itself.

try this command

What is that error means? I have all extensions mentioned above are available and enabled in my php.ini.
Try running:
sudo apt install php7.2-mbstring php7.2-xml
You are missing these extensions from your system and/or they are not configured to be enabled with php. This will install and enable them in your php.ini file.
I have already installed these packages.

step1: first better to remove the php from your ubuntu using this command.
it will only remove php and its modules
sudo apt-get purge `dpkg -l | grep php| awk '{print $2}' |tr "\n" " "`
step2: PHP 7.1 isn’t available on Ubuntu default repositories… in order to install it,
you will have to get it from third-party repositories.
Run the commands below to add the below third party repository to install PHP 7.1
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
step:3
now install the required modules.
sudo apt-get install php7.1 libapache2-mod-php7.1 php7.1-common php7.1-mbstring php7.1-xmlrpc php7.1-soap php7.1-gd php7.1-xml php7.1-intl php7.1-mysql php7.1-cli php7.1-mcrypt php7.1-zip php7.1-curl composer
I got the same error, using this command error is resolved
sudo apt-get install php-bcmath php-soap

C:\wamp\www>*
I am using windows.
I have tried installing a fresh composer, I have tried copying a laravel directory and placing it in my /www manually.
I've made sure that WAMP is using all modules and extensions according to what I read.
I've edited the php.ini file and taken of the semi-colons where necessary.
And now after a bit of Google Searching, I am lost.
Could anybody help me with this problem please, I would appreciate it.
Thanks in advance!
Below is my PHP.ini file
So I couldn't paste the whole thing, but take a look at it here:
http://jpst.it/AAhW
I had the same problem. Here's the solution.
Go to your php.ini file.
Locate the extension "extension=php_mbstring.dll". (ctrl+f might not work, just locate the long list with extensions in php.ini)
Uncomment the extension, you do this by removing the semicolon in the same line.
Save your php.ini file.
This probably won't be the last time you'll encounter something like this. As a rule of thumb, read the error carefully and make the appropriate change to your php.ini file.
Good luck!
Installing php-mbstring using,
sudo apt-get install php-mbstring
should fix this.
There are couple of errors when i was trying to install on my linux machine :
laravel/framework v5.4.9 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.

sudo apt-get install php-mbstring

jenssegers/mongodb v3.2.2 requires mongodb/mongodb ^1.0.0 -> satisfiable by mongodb/mongodb[1.0.0, 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.0.5, 1.1.0, 1.1.1, 1.1.2].
mongodb/mongodb 1.1.2 requires ext-mongodb ^1.2.0 -> the requested PHP extension mongodb is missing from your system.
you can simply run the following commands:
sudo apt-get install php-*
Thanks
