When run krakenuniq-build I get this error message:

Hi, thanks for creating such a useful tool!
When I use krakenuniq(version 1.0.4), I download the database first by code:
When run
krakenuniq-build
I get this error message:So I gave up building it myself and used the built database. But the running result was unclassified.(https://benlangmead.github.io/aws-indexes/k2)
When run
krakenuniq
I get this error message:can you help point out the reason why the build failed?
Secondly, I hope you can point out why when downloading the built database and running it, all the results are unclassified.
Thank you very much.
