phpunit no phpstorm

Question

I’ll run unit tests for phpunit in my stage and I can’t put it in the project. I added the file composer.json and when I will try to add dependency phpunit/phpunit, it presents the following error:

composer require phpunit/phpunit:8.0.4 -n --no-progress --no-interaction
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- Installation request for phpunit/phpunit 8.0.4 -> satisfiable by phpunit/phpunit[8.0.4].
- phpunit/phpunit 8.0.4 requires php ^7.2 -> your PHP version (7.0.33) does not satisfy that requirement.

Installation failed, reverting ./composer.json to its original content.

Answer 1

When I see your code, I see that your machine does not have the mbstring extension.

phpunit/phpunit 8.0.4 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.

You must install this extension (or activate it) before trying to install Phpunit.

Solution 1 - Activating the extension:

Look for the php.ini configuration file on your machine. To find where it is, type the command in the terminal php -i.

Search in the first lines a line started like this: Configuration File (php.ini) Path. What comes next indicates the folder where your configuration file is.

Locate this folder and open the file php.ini. Then add the following line:

(If you are on Windows)

extension=php_mbstring.dll

(If you are on Linux)

extension=php_mbstring.so

Run the installation command again. If you are giving error, let’s go to the 2nd solution:

Solution 2 - Activating mbstring

In Ubuntu you must execute the following command:

sudo apt install php-mbstring

I think with that, you should solve your problem.

I hope I’ve helped.

Issue #1 to reflect changes to the question

The mistake: Problem 1 - Installation request for phpunit/phpunit 8.0.4 -> satisfiable by phpunit/phpunit[8.0.4]. - phpunit/phpunit 8.0.4 requires php ^7.2 -> your PHP version (7.0.33) does not satisfy that requirement. indicates that the PHP version is not supported by the latest version of Phpunit.

You can solve it in two ways:

• Installing an old version of Phpunit or,
• Installing a newer version of PHP.

I hope I’ve helped.
