Can't install some melpa packages in emacs

I'm just trying out emacs (coming from vim).

I've run M-x package-refresh-contents multiple times but still, many packages that I'd like to install aren't listed. For example, go-mode

trying to install go-mode

Any idea where I've messed up? Thanks!

EDIT

I just tried out spacemacs, and the packages I want show up in the list...

Solution

  • As explained in the comments, the behavior you got is just a feature of package.el (not a bug :)

    Namely, after installing a MELPA package with M-x package-install RET …, this package is not proposed anymore for installation.

    To check whether a package has indeed been installed, you can either:

    Side notes

    It may be useful to upgrade all installed MELPA packages from time to time, by typing:

    Also, beyond the builtin Emacs package manager, you may be interested in the use-package tool:
