Fatal error call to undefined function imagecreatefromjpeg

I’ve searched for this and the solutions provided in past questions are completely incomprehensible to me. Whenever I run functions like imagecreatefromjpeg , I get this:

Fatal error: Call to undefined function imagecreatefromjpeg() .

I’m working on a new install of PHP; my last installation never had this problem. I don’t get what’s going on.

Погуглив, нашла только варианты, когда надо добавить в докерфайл библиотеки libjpeg-dev и libpng-dev, но они уже есть.
