找出构建二进制文件的版本吗？

Question

Is there a way to tell what go version a binary was built with?

I have multiple go instances on my workstation, so I want to verify that the correct one was used.

Answer 1

Use runtime.Version() at runtime to figure out what version of Go your binary was built with:

func Version() string

Version returns the Go tree's version string. It is either a sequence number or, when possible, a release tag like "release.2010-03-04". A trailing + indicates that the tree had local modifications at the time of the build.
