Question

我正在尝试通过使用以下方法从Github存储库进行克隆来运行示例cordapp-example代码：

git clone https://github.com/corda/samples

我遵循了文档中提到的所有步骤，以从IntelliJ运行应用程序。

[ERROR] 14:54:18,832 [main] internal.DriverDSLImpl. - Driver shutting down because of exception [errorCode=1crywct, moreInformationAt=https://errors.corda.net/OS/4.3/1crywct]

我看到以下描述：

[ERROR] 14:13:50,501 [main] internal.DriverDSLImpl. - Driver shutting down because of exception [errorCode=1crywct, moreInformationAt=https://errors.corda.net/OS/4.3/1crywct]

以前是否有其他人看到过这种情况，是否有解决此问题的建议或关于如何进一步调试的线索？

Answer 1

从错误消息中，我将看到以下内容：

"Unable to start notaries. A required port might be bound already"

这意味着公证人使用的端口正在由其他应用程序使用，或者很可能正在由其他正在运行的公证人使用。

如何解决？

在您的公证文件夹中打开node.conf，然后检查列出的端口，例如

address : "localhost:10006"

然后检查系统中的端口使用情况，要么终止正在运行的进程，要么更改公证node.conf中的端口，然后再次运行。

祝你好运。
