ERROR: expected package `PkgAuthentication [4722fa14]` to be registered

Question

I am using JuliaPro v1.4 on Windows 10. I was trying to install a package but the REPL got stuck so I interrupted it. Since then I'm no longer able to install any package due to this error. Any ideas?

Answer 1

If you are in the right directory (where the manifest/project file are), just doing up and resolve in the package manager will resolve this.

Answer 2

In the REPL (in the repo where you'd like to install the package):

• Switch to "Pkg mode" by typing ]
• Type up + enter
• Type resolve + enter
• Try re-installing the desired package
