在 go 中删除跟踪中的模块路径

Question

我需要删除跟踪中与导入模块相对应的绝对路径。即使我这样编译我的程序：go build -gcflags=-trimpath=$GOPATH -asmflags=-trimpath=$GOPATH 我仍然得到模块文件的完整路径，出现恐慌的地方，尽管程序的非模块文件没有显示完整路径：

goroutine 1 [running]:
monitors/fibre_monitor/logging.FileHandler(0x5e6755, 0x1a, 0x441, 0x0, 0x6fc23ac00, 0x1, 0x500000, 0xc000000002, 0xb)
        /home/gtristan/go/src/monitors/fibre_monitor/logging/file_handler.go:182 +0x11f
main.python_logger(0x5e1383, 0x5, 0x5e6755, 0x1a, 0x101)
        src/monitors/fibre_monitor/fibre_monitor.go:73 +0x1b5
main.main_check(0x0, 0xc00008e058)
        src/monitors/fibre_monitor/fibre_monitor.go:343 +0x65
main.main()
        src/monitors/fibre_monitor/fibre_monitor.go:428 +0x56

有什么解决方案可以摆脱跟踪中各处的 GOPATH？

Answer 1

将 -trimpath 参数用于 go build（而不是 gcflags 或 asmflags）：

没有-trimpath:

$ go build .
$ ./panic 
panic: bleh

goroutine 1 [running]:
main.example(0xc000046738, 0x2, 0x4, 0x473f2b, 0x5, 0xa)
    /home/me/stuff/src/github.com/me/testing/panic/main.go:9 +0x39
main.main()
    /home/me/stuff/src/github.com/me/testing/panic/main.go:4 +0x72

与-trimpath:

$ go build -trimpath  .
$ ./panic 
panic: bleh

goroutine 1 [running]:
main.example(0xc000046738, 0x2, 0x4, 0x473f2b, 0x5, 0xa)
    github.com/me/testing/panic/main.go:9 +0x39
main.main()
    github.com/me/testing/panic/main.go:4 +0x72

根据 go help build:

    -trimpath
        remove all file system paths from the resulting executable.
        Instead of absolute file system paths, the recorded file names
        will begin with either "go" (for the standard library),
        or a module path@version (when using modules),
        or a plain import path (when using GOPATH).
