无法在Node.js中创build〜1.2GB的Uint8Array

以下JavaScript代码：

new Uint8Array(1253377279) 

当运行node.js结果是：

 RangeError: length > kMaxLength at repl:1:2 at REPLServer.self.eval (repl.js:110:21) at Interface.<anonymous> (repl.js:239:12) at Interface.emit (events.js:95:17) at Interface._onLine (readline.js:202:10) at Interface._line (readline.js:531:8) at Interface._ttyWrite (readline.js:760:14) at ReadStream.onkeypress (readline.js:99:10) at ReadStream.emit (events.js:98:17) at emitKey (readline.js:1095:12) 

奇怪的是，考虑到我有8GB的内存，足以填满arrays几次。 我试过了： – --max-old-space-size=1900没有成功。 我能做什么？
