I’m wasn’t sure what to do with that.
Here is how I finally got it work after a bunch of trial and error:
In the error message it says about using export JULIA_SSL_CA_ROOTS_PATH="" .
On Windows, I took that to meaning using the Environmental variables in Windows GUI. So I created a variable for that and set it to “”. That didn’t work.
Solution
Works for both MacOS and Windows: It turns out adding the following to startup.jl works. I can now run the packages update from inside Terminus in Sublime Text.
ENV["JULIA_SSL_CA_ROOTS_PATH"] = ""
