Fatal error: Uncaught Error: Call to undefined function Spatie\ImageOptimizer\mime_content_type()

I am trying to use this package into wp-cli. When I try to optimize images, I am getting this error.

Fatal error: Uncaught Error: Call to undefined function Spatie\ImageOptimizer\mime_content_type() in /home/xxx/.wp-cli/packages/vendor/spatie/image-optimizer/src/Image.php:22
Stack trace:

#4 [internal function]: TypistTech\ImageOptimizeCommand\Operations\Optimize->TypistTech\ImageOptimizeCommand\Ope in /home/xxx/.wp-cli/packages/vendor/spatie/image-optimizer/src/Image.php on line 22

is there anything missing during installation?
My command is::
wp image-optimize find /home/xxx/public_html --extensions=gif,jpeg,jpg,png,svg

Thanks in advance.

Let's see how spatie/image-optimizer#76 works out.

Just in case you already have fileinfo installed: https://stackoverflow.com/a/24850235

Just configured php fileinfo extension. Looks like it's working now.

How did you configure the fileinfo extension?

Depends on your server.
