我是Rails开发人员，正在尝试安装名为Liveblog的开源应用程序
在台式机上一切正常，但它们还提供了适用于iOS和Android的移动应用程序，我无法将其用于错误提示。
我使用nginx记录了发布请求，这就是日志。
{\"username\":\"xxxxx\",\"password\":\"xxxxx\"}
37.117.49.57 - - [24/Dec/2018:16:59:20 +0100] "POST /api/auth HTTP/1.1" 500 157 "-" "Live Blog Reporter/org.sourcefabric.LiveBlogReporter (22; OS Version 12.1.2 (Build 16C101))" "-"
带有用户和密码的哈希参数看起来不错。
在应用程序日志中，我出现此错误：

在Rails日志错误中，我可以理解问题出在哪里，在这里我无法理解python中的路由是如何工作的，因此无法调试问题。日志中是否有任何我可以用来开始调试的提示？
答案 0 :(得分：0)
用2018-12-24 16:01:56.101 UTC [main] InitCmd -> ERRO 001 Cannot run peer because cannot init crypto, folder "/etc/hyperledger/msp/users/Admin@gov.snts.com/msp" does not exist
=>进行了解释，您可以查看回溯的最后一行，以检查引发（抛出）异常的代码行。
如果未在异常本身中记录运行时值，则在此处添加调试器断点。
在您的情况下：Traceback (most recent call last):是raise NotImplementedError()中抛出的手动异常。
