Incompatible with use-package?

[seagle0128]

After enabling feather-mode, I tried to install some packages like this:

(use-package exec-path-from-shell
    :init (exec-path-from-shell-initialize))

I got the error: exec-path-from-shell-initialize cannot be found. I guess it's related to the behavior of the parallels installation. Can you please let me know how to handle this?

Ref: README - notice.

When feather-mode is enabled, package-install will change to a promise function, which will not block the main Elisp thread.
With feather-add-after-installed-hook-sexp, you can register S-expressions to be evaluated after installation.

However, the syntax is redundant, so using leaf.el is the better way to go.
