Symfony 4 nor install correct version

问题

So now I have been working with symfony 3.3 Try to follow the instructions to install symfony 4 with composer but install symfony 3.4.6 How can I achieve it?

回答1:

try :

composer create-project symfony/skeleton "dev-master"

if it doesn't work, so you should update your composer version

composer self-update

if the problem remains clear composer cache and retry

composer clearcache
