How reliable is it to copy the .julia folder as a way to install packages without internet access? That is, can this procedure work, assuming that computers A and B have the same OS and processor?
Computer A has access to internet. I install several packages on computer A.
Computer B does not have internet access. I copy the .julia folder from computer A and place it in the default location in computer B.
To get Julia working on a computer without internet access:
Install desired packages onto a computer with internet access.
Copy entire .julia directory and transfer onto the computer without internet access.
This works for me when both computers are running Windows10. I assume you could do the same with other operating systems as long as the operating system on both computers is the same.
