Error installing Symphony: fopen failed to open stream: Unable to find the socket transport "http"

Question

I’m following the tutorial for the installation of symfony, but an error occurs while running it

  [GuzzleHttp\Exception\RequestException]
  Error creating resource: [message] fopen(https://get.symfony.com/symfony.version): failed to open stream: Unable to find
   the socket transport "http" - did you forget to enable it when you configured PHP?

I have installed apt-get install php5-Curl and even then, the problem remains

Answer 1

This might be your SSL not activated, to activate with PHP5 no Ubuntu va no php.ini and uncomment (remove the ; in front of the extesion=) the line:

;extension=openssl.so

Should stay like this:

extension=openssl.so

If it’s Windows uncomment:

;extension=php_openssl.dll

If it is PHP7.2 (windows and linux):

;extension=openssl

Another solution you can try is to activate CURL using the following command:

 sudo apt-get install php5-curl

If it’s already installed and still doesn’t work, you can edit it in php.ini and uncomment the line (if it’s php5 with linux):

;extension=php_curl.dll

If it is windows:

;extension=curl.so

If it is PHP7.2 (windows and linux):

;extension=curl
