下载了完整webrtc代码后，node.js 报错，代码在同事机上能跑，我机子报错

Question

在 github上下载了别人的完整代码后，运行服务器，总是报错
const TRAILER = Buffer.from([0x00, 0x00, 0xff, 0xff]);

                   ^

TypeError: this is not a typed array.

Process finished with exit code 1

求问，如何解决这个问题，

PS:代码在同事机子能跑，我机子失败，我是Win10， 他Win7 但是我不觉得是这个原因

Buffer.from() This method was introduced in node 6.0. Websocke uses this method so. The solution is to upgrade the local nodejs version to 6.0+
