How to have emacs, on startup, have the environment as if having read my bashrc?

In my .emacs, I have some stuff that uses environment variables defined by my .bashrc.

If I first open a terminal (which automatically reads me bashrc), and then open emacs from there, I can get everything to work. However, if I open if from GNOME's activities, it doesn't.

Is there a way to still open emacs from GNOME's activities, but have it have the environment of by .bashrc?

I wrote a tutorial about this. exec-path-from-shell can significantly increase Emacs's startup time. I prefer the Doom Emacs approach: save the shell environment to a file, and load it when Emacs starts. My article shows how to do that.

You can use exec-path-from-shell, this will load all your shell variables as like you start emacs from terminal.

Or you can add them manually. e.g :

(defun aza-latex-path ()
  (setenv "PATH" (concat "/usr/local/texlive/2018/bin/x86_64-linux:"
                         (getenv "PATH")))
  (add-to-list 'exec-path "/usr/local/texlive/2018/bin/x86_64-linux"))

(defun aza-go-path ()
  (setenv "PATH" (concat "/usr/local/go/bin:"
                         (getenv "PATH")))
  (add-to-list 'exec-path "/usr/local/go/bin"))

You should probably be defining your environment variables in your ~/.profile not your ~/.bashrc so they are just loaded once during login instead of every time you launch a shell and emacs would have access to them when launched from activities by default.

But you could set a custom shortcut to launch emacs from a login shell if that's how you want to do it: e.g, => settings -> keyboard -> create custom shortcut with command like bash -l -c 'emacsclient -nc -a "" &' to launch emacs from a login shell which should read your .bashrc.
