How to install a julia package offline in Julia 1.0?

I have my own julia package works well on Julia 0.6. When I try to upgrade to julia 1.0, I found it's more difficult to add my own package in Julia 1.0. I cannot just put it under pkg.dir(). In my situation, the package is just several files on my local disk and don't rely on anything else except julia itself. I could use it with 'generate' and 'activate' in the new package manager, however, after restart the REPL, I have to redo the 'generate' and 'activate'. Is there a way to install the package perpetually? Thank you!

I tried put my own package files under JULIA_DEPOT_PATH/MyPackageName/src . I also tried put the files under MyPackageName/random-five-char/src/. Neither works.

In fact, you don't have to. Did you try activate /your/package/path/package_name instead of activate package_name?

IIUC, what you'd like is to install the package in the default environment(e.g. (1.0)). The simplest way to do this is dev /your/package/path/package_name.
