Could you please once remove _vendor?

Could you please once remove vendor

I still get error even if _vendor is removed.

Did you set GO15VENDOREXPERIMENT=0 ?

In this environment, moveSrcToVendor is called twice at this line and this line

[mattn]

Yes, moveSrcToVendor is called after build/install.

[mattn]

But your gom command (I don't know the version of gom) may be do it because behavior moveSrcToVendor was changed in few days ago.

[syohex]

I use latest gom.

In this environment, moveSrcToVendor is called twice at this line and this line

Before first moveSrcToVendor call

% ls _vendor
bin/  pkg/  src/

After first moveSrcToVendor call

% ls _vendor
bin/  github.com/  pkg/

Before second moveSrcToVendor call

% ls _vendor
bin/  github.com/  pkg/

_vendor/src is already moved, so second moveSrcToVendor is falied.

[mattn]

What do you mean second?

When gom install,

1. move _vendor/github.com to _vendor/src (moveSrcToVendorSrc)
2. go get
3. move _vendor/src/* to _vendor/ (moveSrcToVendor )

[syohex]

Sorry for confused. Second means moveSrcToVendor at this point(https://github.com/mattn/gom/blob/a2d474243cd5b5b6c4aa5abdf344a0040225f0fe/install.go#L568). (first call is here(https://github.com/mattn/gom/blob/a2d474243cd5b5b6c4aa5abdf344a0040225f0fe/install.go#L316)

[mattn]

could you please update gom?

[syohex]

Error is gone. Thanks.
