Hey, go get go.etcd.io/etcd/client/v3 should be the correct one, can you give that a try?

[linnv]

one way to solve this issue is to replace the etcd package with local dir, for example:

//clone the etcd package to your localhost
cd $GOPATH
git clone -b v3.5.0 https://github.com/etcd-io/etcd.git
cd etcd
pwd
// get the local dir of etcd: /Users/jialinwu/go12/etcd, it depends on your $GOPTAH

in go file import go.etcd.io/etcd/client/v3,then you need to add replace go.etcd.io/etcd/client/v3 => /Users/jialinwu/go12/etcd/client/v3 to go.mod

and there is a gist for more detail https://gist.github.com/linnv/aebee312b140dd4cee56e153a1a691e5

@linnv how come you need to do this? For me:

go get go.etcd.io/etcd/client/v3

works correctly and then following the rest of the README https://github.com/etcd-io/etcd/tree/main/client/v3#install. If there is an issue that we need to replace this, let us know so we can fix it!

It works for me too! Thanks for mentioning me!
@forging2012 just try go.etcd.io/etcd/client/v3 , no go.etcd.io/etcd/clientv3, they are different.

[forging2012]

Done
Thanks all!

Suggest:
ADD this FAQ to README file.

We have this in the client readme already https://github.com/etcd-io/etcd/tree/main/client/v3#install, where else would you like to have it for more visibility?

Nice job !
But, It does confuse people, like me.

@forging2012 feel free to open PR to correct how it could be more clear for everyone, thank you!
