Fatal error: Uncaught exception in aws.phar

[mayng0702]

Hi, I use aws php sdk and aws.phar but I got a error msg. I changed ";extension=php_mbstring.dll" to "extension=php_mbstring.dll" in php.init-development but it cannot run successfully. The error message is "Fatal error: Uncaught exception 'Aws\DynamoDb\Exception\DynamoDbException' with message 'Error executing "ListTables" on XXXXXx ; AWS HTTP error: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)' GuzzleHttp\Exception\RequestException: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) in phar /aws.phar/GuzzleHttp/Handler/CurlFactory.php(155): GuzzleHttp\Handler\CurlFactory::createRejection(Object(GuzzleHttp\Handler\EasyHandle), Array). Does anyone can give me a solution?
