Golang Revel Assertf 引起恐慌

Question

我创建了 revel 测试套件，我使用 Assertf 检查错误。

t.Assertf(err == nil, "error occurred: %v", err)

它在我的 Windows 和 Mac OSX 中没有任何问题。但是在我的远程服务器 Ubuntu 16.04 中，每当断言错误时，我都会收到这样的错误消息。

Answer 1

断言触发恐慌，恐慌过滤器失败，因为它无法找到导致错误的 go 代码的源文件。如果您从部署中删除了源文件，这可能会导致这种情况（恕我直言，它确实不应该）但是查看它试图加载堆栈说有错误的文件的代码。

Answer 2

这是由于 revel 中的错误 - https://github.com/revel/revel/issues/1287

问题是您的服务器将 GOPATH 设置为 /go，并且 Revel 错误地将堆栈跟踪的第一帧 (/usr/local/go/src/runtime/debug/stack.go:24) 识别为在 GOPATH 中，因为它包含 /go/src.您可以通过在您的服务器上手动 setting/maintaining 一个不包含 /go 路径中任何地方的不同 GOPATH 来解决这个问题。这也是在 https://hub.docker.com/_/golang/

找到的官方 docker 容器的问题
