Answer 1

Open php.ini and increase the default_socket_timeout value. For example: default_socket_timeout=360 (default is -1 or 60)

Answer 2

I think this is a weird situation, either

• Climb the wall

• Use domestic composer image

Answer 3

Try changing to domestic mirror

Answer 4

Try using a browser to request https://install.phpcomposer.com/installer, download the file and transfer it to the server and rename it to composer-setup.php

Answer 5
