That's really strange. Nothing in the project should be loading anything from gx anymore.

@frrist, can you look into this one?

[frrist]

Hi @jscode017 this looks like it could be an issue with cached deps.

To clear your go mode cache you can run: go clean -n -modcache. Then rerun go run ./build deps and go run ./build build.

If the problem persists, please share the output of the three aforementioned commands here and we will investigate further.

This happens on 0.1.4(user devnet release), haven't seen this in master.
go run ./build deps would get the gx repo, but that branch seems to have other problems as well

end of go run ./build deps

I'm still installing deps not sure if it will work
But the comment of @kishansagathiya remind me something.
I has previously install the version of git tag 0.1.4, maybe that is what cause the problem?
sorry that I did not mention this

[jscode017]

After deleting the $GOPATH/bin/go-filecoin
and rerun the whole building process, it built successfully and tests seems to pass
So maybe should delete go-filecoin in $GOPATH/bin before reinstall?

[frrist]

@kishansagathiya I believe the errors you are seeing are due to the environment variable GO111MODULE being set to on when running deps on 0.1.4 (which doesn't use go mod, I have been able to reproduce the errors you are seeing by running deps with GO111MODULE=on on version 0.1.4). Can you set GO111MODULE to off (export GO111MODULE=off) and run deps again? I believe this will fix your problem when building 0.1.4.

@jscode017 did you clear your go mod cache (go clean -n -modcache) before running deps again on 0.1.4? I don't believe deleting your filecoin binary will have any effect on the issue you were facing.

[jscode017]

@frrist my scenario is that I built 0.1.4 first, and then built the newest commit
And somehow when I had go-filecoin(0.1.4 version) in my $GOPATH/bin, the building process won't compile files, maybe there is some setting I do causes it fail?
Kinds of weird, however, thankfully my issue is solved.

[kishansagathiya]

Can you set GO111MODULE to off

that worked, thanks @frrist

@jscode017 this behaviour is not something I am familiar with, but I am happy it resolved your issue. Since it sounds like this has fixed the problem I am going to close this issue. If the problem resurfaces feel free to reopen and share your output.
