I get, but what gives me trouble is that npm package isn't updated yet

This means that react-lazyload is defined to be compatible with earlier versions of react (0.14.0, 15.x, 16.x, 17.x).

To solve this problem, you can try the following methods:

1. using the legacy-peer-defs option
   With this option, npm ignores incompatible peer dependencies and attempts to install them. This is one of the simplest solutions.

npm install --save react-lazyload --legacy-peer-deps

2. --using the force option
   This option ignores any conflicts that occur during the installation process and forces the installation to proceed. However, this method should be used carefully as it can potentially result in broken dependencies.

npm install --save react-lazyload --force

3. Use compatible libraries
   You can use another library that is compatible with React 18 instead of React-lazyload. For example, you can use libraries such as React-lazy-load-image-component or React-intersection-observor.

react-lazy-load-image-component

npm install --save react-lazy-load-image-component
