Thanks a lot ! I read up a bit about go module, but I'm still not able to solve this problem. when I'm running `go build`, I'm getting this error
```
go: github.com/ipfs/go-ipfs@v0.4.22 requires
        github.com/go-critic/go-critic@v0.0.0-20181204210945-ee9bf5809ead: invalid pseudo-version: does not match version-control timestamp (2019-02-10T22:04:43Z)
