Can't install SonataAdminBundle for Symfony 4

Question

Have installed via Composer clear Symfony 4.1

Then i try to install via Composer SonataAdmin but get error with message:

sonata-project/admin-bundle 3.38.3 requires symfony/class-loader ^2.8 || ^
3.2 -> satisfiable by symfony/class-loader[3.4.x-dev] but these conflict with yo
ur requirements or minimum-stability.

In symfony 4 documentation says, that symfony/class-loader component deleted in this version.

How can i install SonataAdmin for Symfony 4.1 using Composer?
