Try this

composer require nwidart/db-exporter dev-master

[flaird]

No longer spits out that output, Thanks @jeff1326

[giolvani]

@jeff1326 it works for me, thanks!

But, why doesn't work without specifying the version?

I saw, this error happens with all lib that I try to install... :(

[nWidart]

Pretty simple, and probably should have done it already, but it's because there isn't a tagged version with the, yet.

Edit, I've just tagged this version. You can now use version ~1.1.
