بعد از نصب سرور مجازی (در اینجا xampp) مسیر php رو به کامپیوتر دادم
بعد خواستم کامپوزر رو نصب کنم که یه همچین خطایی میده:
The Composer installer script was not successful [exit code 1].
Your proxy settings may be causing this error.
Script Output:
The "https://getcomposer.org/versions" file could not be downloaded: Failed to open stream: No connection could be made because the target machine actively refused it
