When installing Symfony 4, some components did not download - Downloading (failed), how to fix it?

Question

symfony

Install Symfony 4:

composer create-project symfony/website-skeleton theproject

Most of the components installed, but an error occurred for four

Downloading (failed)

Specifically, failed to download:

symfony/expression-language
symfony/monolog-bridge
symfony/validator
symfony/profiler-pack

As far as I understand, this can lead to problems in the future, how to deal with it?
How can I install them if their download failed when installing symfony?
Thank you!
