What did you do?

ran gomobile version after go get golang.org/x/mobile/cmd/gomobile go init

What did you expect to see?

the version number

What did you see instead?

gomobile version gomobile version unknown: mobile repo git log failed: exit status 128, fatal: not a git repository (or any of the parent directories): .git

[hyangah]

This seems to be another part of gomobile that does not work with the workflow assumed in the module mode. For version, it assumes there is a git repository checked out under GOPATH, which is no longer true in the module mode.

@mandelmonkey What will happen if it is built with GOPATH mode?

GO111MODULE=off go get golang.org/x/mobile/cmd/gomobile

[mandelmonkey]

@hyangah I get package golang.org/x/mobile/cmd/gomobile: cannot find package "golang.org/x/mobile/cmd/gomobile" in any of: /usr/local/go/src/golang.org/x/mobile/cmd/gomobile (from $GOROOT) /Users/chris/go/src/golang.org/x/mobile/cmd/gomobile (from $GOPATH)

[hyangah]

I cannot reproduce it.
@mandelmonkey Have you checked if go get fetched the source file in your $GOPATH/src/.. directory? Or is your $GOPATH not writable?

@hyangah so the error says cannot find package "golang.org/x/mobile/cmd/gomobile" in any of: /usr/local/go/src/golang.org/x/mobile/cmd/gomobile

but I dont have go installed in the /usr/local/ directory is is in the go is installed in /Users/chris/

I need to install go globally?

[hyangah]

@mandelmonkey No. /usr/local/go/ is your GOROOT which you don't ever want to have gomobile source code at all. The second one (/Users/chris/go/...) is from your default GOPATH. Please check whether go get successfully cloned the git repo under /Users/chris/go/src/golang.org/x/mobile/. go get -x -v will show the details.

[mandelmonkey]

@hyangah
here are the results

[hyangah]

Some strange shell issue? -x and -v are valid flags and it seems that it's not recognized.

[mandelmonkey]

hmm not sure, something changed I get Christians-MacBook-Pro:go chris$ gomobile version gomobile version unknown: binary is out of date, re-install it now a few other coworkers have the same issue, is it a MACOS thing?

[hyangah]

Again try
GO111MODULE=off gomobile version

Or go to an empty directory and run gomobile version.
From your go env output, I guess the go command is operating in module mode due to the presence of a go.mod file.

This time, try to avoid copy and paste. Seems like the copy-and-paste inserted extra characters like non-breaking space characters.

[mandelmonkey]

no prob, I tried again Again try GO111MODULE=off gomobile version

And got

Christians-MacBook-Pro:~ chris$ GO111MODULE=off gomobile version
gomobile version unknown: cannot test gomobile binary: exit status 1, can't load package: package golang.org/x/mobile/cmd/gomobile: cannot find package "golang.org/x/mobile/cmd/gomobile" in any of:

	/Users/chris/go/src/golang.org/x/mobile/cmd/gomobile (from $GOPATH)

moved to an empty directory and ran these

Maybe try go get golang.org/x/mobile/cmd/gomobile again from outside any directory that has go.mod. Then run gomobile version from any path. It could be you have to rebuild the binary because it wasn't installed correctly the first time (e.g. fetched from a directory that has go.mod in it).
