Ao tentar instalar o composer no Windows, não sei se é por estar numa rede que utiliza proxy, aparece a seguinte mensagem de erro no início da instalação:
"The Composer installer script was not successful [exit code 1].
Script Output: The "https://getcomposer.org/versions" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages: error:1408F10B:SSL routines:ssl3_get_record:wrong version number Failed to enable crypto failed to open stream: operation failed"
Sabem o que pode ser?
