Error No system CA bundle could be found

I use Google API to write data to google sheet. I get this error:

No system CA bundle could be found in any of the the common system locations. PHP versions earlier than 5.6 are not properly configured to use the system's CA bundle by default.
...

Solved: Append this code:

# $client = new Google_Client(); #...
$client->setHttpClient(new GuzzleHttp\Client(['verify'=>false]));

Then my code works!
