looks like the framework hasn't finished loading. Try the full version of composer


I think it may be because of the php version that something parses differently. This problem may occur


phpstudy can switch between php versions on your own, you can try to change some environment first, change to 5.4or 5.6to determine whether it is caused by the PHP version problem. It is initially suspected that this class could not be found because there may be a problem with the automatic loading of the framework. And that's all you gave me. It's hard to guess a specific problem.
