This is not implemented, as it is not possible to implement Argon2i with acceptable performance in pure-PHP

hello ; how can i fix this

See #27375

You need to install ext/sodium through PECL or compile PHP with Argon support enabled (both of which require libsodium installed).

The sodium_compat library cannot polyfill all functions in pure PHP, you have hit one of those cases.

@bybilgili Does that help you? Please report back so we know if we can close this issue, or close it yourself if the above hint helped you to msolve it. Thanks in advance.

ON Your Xampp control panel click on the first config TAB.
Open PHP (php.ini) on your notepad
Ctrl+F and seach for sodium
Enable the extension bearing the name sodium by DELETING the SEMICOLON at the beginning.
Save
Restart Apache by Stopping and Starting Again.
Then try to RUN C:\xampp\htdocs\magento2>
php bin/magento setup:install --base-url=“http://localhost/magento2/” --db-host=“localhost” --db-name=“magento2” --db-user=“root” --db-password=“” --admin-firstname=“admin” --admin-lastname=“admin” --admin-email=“[email protected]” --admin-user=“admin” --admin-password=“admin123” --language=“en_US” --currency=“USD” --timezone=“America/Chicago” --use-rewrites=“1” --backend-frontname=“admin” --search-engine=elasticsearch7 --elasticsearch-host=“localhost” --elasticsearch-port=9200

Goodluck.

This will work for magento - not joomla :)

If you are using LAMPP then this answer can help.

There are 4 solutions to resolve this error on WINDOWS XAMPP.

Solution 1:-

One of the reason for this error is sodium extension not enabled in php.ini file, so we need to enable it and re-run install command in the command prompt.

To enable:-

Go to C:\xampp\php\php.ini, find "extension=sodium" in it and then remove semicolon from beginning of this line to enable PHP extensions sodium. Save the file.

Then restart Apache means stop and start Apache from the Xampp Control Panel.

That’s it.
