What dep command did you run?

dep ensure

$dep ensure -add github.com/braintree/manners

"github.com/braintree/manners" is not imported by your project, and has been temporarily added to Gopkg.lock and vendor/.
If you run "dep ensure" again before actually importing it, it will disappear from Gopkg.lock and vendor/.

$ dep ensure

I did a dep ensure -add without actually importing the package in my code. It threw a warning saying the package would be removed if I did a dep ensure without importing the package.

I imported the package in my code and ran dep ensure again.
dep status says it has the package installed. But the package is missing in the vendor directory.

hi, welcome! sorry you ran into this.

this is a bit odd. could you provide the output of dep hash-inputs?

[darkpssngr]

[darkpssngr]

Its weird. I see the package now after running dep hash-inputs.
Not sure what happened.

[sdboyer]

hmm, dep hash-inputs is a read-only operation, so that shouldn't have changed anything.

are you able to reproduce the original problem from scratch?

[darkpssngr]

No. I'm unable to reproduce it now. Will close this for now.

Thanks

I am facing the same issue.

$ dep ensure

The package github.com/streadway/amqp is not being fetched in the vendor directory.

[vaibhav-sinha]

So I start to see the package too after few minutes. Maybe the package is just taking time to get downloaded? Does ensure not wait until the download is over?

[sdboyer]

@vaibhav-sinha dep is pretty powerful, but it's not magical enough to do things when the process isn't running 😄

if you still have the terminal history, that'd help to figure out how you ran into this. the only known hole through which this should be able to occur is if you manually delete something out of your vendor directory - dep sometimes won't repopulate it if Gopkg.lock is already in sync, unless you run dep ensure -vendor-only.

we've chosen to leave that hole in place temporarily while we work on #121, because the alternative would entail absolutely always unconditionally repopulating vendor completely on every dep ensure run.

[beeekind]

I ran into a similar issue and found that deleting my vendor directory and running 'dep ensure' retrieved the missing package. Unfortunately I don't have steps to reproduce. I've run into the issue before and will be more diligent recording the steps next time.

Otherwise solid tool, very grateful to the devs/maintainers!

[halakaraki]

I faced the same issue. Deleting the vendor directory and then running dep ensure worked but I'm not sure what caused it.
