Julia中调试函数的替代品是什么？

即使试过docker也找不到合适的替代品

julia> debug("hello")
ERROR: UndefVarError: debug not defined
Stacktrace:
 [1] top-level scope at REPL[6]:1

使用宏打印调试输出

您必须启用调试输出才能真正看到它。您可以使用env变量

JULIA\u DEBUG

启用它：

help?> debug
search: @debug

Couldn't find debug
Perhaps you meant @debug, @enum, big or detach
  No documentation found.

  Binding debug does not exist.

julia> @debug "hello"

julia> ENV["JULIA_DEBUG"] = "all"
"all"

julia> @debug "hello"
┌ Debug: hello
└ @ Main REPL[4]:1
