[Composer\Exception\NoSslException]
The openssl extension is required for SSL/TLS protection but is not available. If you can not enable the openssl ex
tension, you can disable this error, at your own risk, by setting the 'disable-tls' option to true.
打開php/php.ini
把大概901行前面的分號去掉
---------------------------------------下面是php_openssl.dll詳解,是一套用於SSL/TLS協議的加密工具---------------------------------------
