It looks like you 1.13 installation is somehow messed up. Did this start immediately after upgrading to 1.13 ? Can you run other programs using 1.13 ?

[orange-jacky]

yes, i run gomobile after upgrading to 1.13, and i can run my other go code using 1.13 without wrong info, only runing gomobile it failed.

Please try go install golang.org/x/mobile/cmd/... to rebuild the gomobile (and gobind) tool.

[orange-jacky]

thanks, i rebuild the gomobile (and gobind) tool, it works
