add package problem

[userchba]

when I add any package, this issue will occur, but at fist time of installing julia, I can add the package. I don't know the reason. I have tried to delete the julia(~/.julia) and reinstall the julia, but the issue is still here. Appreciate it if there is anyone can give a helping hand.

This is not an issue with this package in particular. I've seen people run into this when interrupting a download but restarting julia fixed it then. Anyway, nothing that can be fixed here.
