In my case, this was caused by Microsoft Defender, it may be any other firewall block.在我的情况下，这是由 Microsoft Defender 引起的，它可能是任何其他防火墙阻止。 Try running "firebase emulators:start" in the same cmd window, if you get a message from MS Defender, click "Allow".尝试在同一 cmd window 中运行“firebase emulators:start”，如果您收到来自 MS Defender 的消息，请单击“允许”。 Then you can stop the emulators and run "firebase functions:shell" in the same cmd window, it should work properly.然后你可以停止模拟器并在同一个 cmd window 中运行“firebase 函数：shell”，它应该可以正常工作。

In my case, after running "firebase emulators:start" everything worked.在我的例子中，运行“firebase emulators:start”后一切正常。 It appeared that the command installed a few.jar files and perhaps that was the reason.该命令似乎安装了几个 .jar 文件，也许这就是原因。
