Gopls was built with Go version 1.17, which will be unsupported by gopls v0.13.0. Please upgrade to Go 1.18
or later and reinstall gopls. If you can't upgrade and want this message to go away, please install gopls v0.110. See
https://go.dev/s/gopls-support-policy for more detaails
升级了go、coc.nvim 版本后底下会一闪而过这段信息，全文大概是上面这样的。反正我去升级gopls解决了问题。
go install golang.org/x/tools/gopls@latest
