2 个解决方案

#1

In png-stream.js change the following lines:

在png-stream。js修改如下行:

server.listen(8080, function() {
  console.log('Serving latest png on port 8080 ...');
});

To a different port, 8081 for instance:

到另一个端口，例如8081:

server.listen(8081, function() {
  console.log('Serving latest png on port 8081 ...');
});

#2

You need sudo/admin priviliges on your machine to run it on port 8080 or any port used. You will need to start with sudo on linux.

您需要在机器上的sudo/admin特权才能在端口8080或使用的任何端口上运行它。您需要从linux上的sudo开始。
