How do I transfer my packages after installing a new Julia version?

Question

I recently updated my Julia installation (to v1.3), but my packages didn't transfer automatically. What's the easiest way to transfer/add them all to the new version?

Answer 1

Go into the environments folder in your .Julia folder and then copy and paste the Project.toml and Manifest.toml file into the 1.3 environment folder.

Note that if the 1.3 folder doesn’t show up initially, just add something random in the package manager to generate the Project and Manifest file.
