What's the best way to install packages in spacemacs?
1. Using M-x package-install
2. Include the packages to be installed in dotspacemacs-additional-packages
3. (use-package )
I couldn't find a definite answer anywhere.
Using the package-install to install packages modified the package-selected-packages automatically. Shall I remove all the packages there and include them in dotspacemacs-additional-packages?
I want to keep my .emacs synchronised between my local mac and my home directory in a linux server. So, I was wondering about removing this automatically modified package-selected-packages variable.

I am using spacemacs and I am attempting to install packages with M-x "package install $package-name". The particular package I am trying to install is SLY, A newer implementation of The SLIME REPL for Common Lisp. When I Install the package when I start up spacemacs it works fine. However when exiting spacemacs it somehow gets deleted. After googling this issue I found this page https://develop.spacemacs.org/doc/FAQ.html. I followed the instructions and changed my .spacemacs config. I added the line dotspacemacs-install-packages 'used-but-keep-unused. What am I doing wrong.
You should add your personal packages to dotspacemacs-additional-packages
Recently I pass to Emacs org because is really convenient to me to write note there.
So I installed all packages I needed (principally ORG and EVIL) but I didn't understand how to setup everything.
I installed emacs from brew without using cask, I linked it, and I'm sure that I'm using the version that I installed (26.1).
So in my ~/ folder I have a .emacs file in which I set up evil mode, and I have a /.emacs.d/ in which I have a lot of file. The problem is: whatever I wrote in a ~/.emacs.d/init.el seems doesn't effect emacs.
So I said "whatever, I'm going on github and I installed some complete configurations and then I customized them myself". I tried to install these two configurations.
https://github.com/hrs/dotfiles
https://github.com/larstvei/dot-emacs?files=1
But for some reason, after doing exactly what they say on README.org
nothing happens.
In particular the second link, after install and open emacs said I need to have ~/.cask/.cask.el but I don't have it.
Advice?
So I downloaded an .el file, I put it on the ~/.emacs.d/elpa/ folder, but it won't appear on the M-x list-packages. How do I make it appear there or how can I install this file/package?
There are two ways of installing an Emacs package: either type M-x list-packages and install it from the list, letting Emacs download it for you, or download the package yourself and install it with M-x package-install-file.
Installing from a package archive
In the first case, note that there are several different package archives. The default value for the variable package-archives only contains GNU ELPA, but most people want to add MELPA to that list since it has more packages. To do that, you need to add the following to your .emacs file (copied from the MELPA web page):
(require 'package) ;; You might already have this line
(add-to-list 'package-archives
'("melpa" . "https://melpa.org/packages/"))
(when (< emacs-major-version 24)
;; For important compatibility libraries like cl-lib
(add-to-list 'package-archives '("gnu" . "http://elpa.gnu.org/packages/")))
(package-initialize) ;; You might already have this line
After that, typing M-x list-packages should list more packages than you'll ever need :)
Installing from a downloaded file
There are two types of packages: single-file packages and multi-file packages. The former can be downloaded as a single .el file, while the latter are distributed as tarballs (.tar). Both types can be installed with M-x package-install-file.
Note that not every .el file can be installed as a package. The comments at the beginning of the file need to follow a certain convention, documented in the Simple packages node of the Emacs Lisp reference manual.
That leaves the possibility that the .el file you've downloaded is not installable as a package. In that case, you should put it in some other directory (~/.emacs.d/elpa is meant for installed packages only), add that directory to the load-path variable, and require the package. If you have foo.el and put it in ~/path/to/foo, it would look something like this:
(add-to-list 'load-path "~/path/to/foo")
(require 'foo)
An .el file is not a package. Installing it via ELPA is probably vastly preferrable to manually downloading a static .el file; perhaps the maintainer has a home page with ELPA (or Marmalade, etc) instructions.
In particular, a package will receive updates as they are made available, so you will not be forever stuck on an increasingly obsolete, unmanaged version (though quiet, fully automatic updates are not yet available or feasible, AFAICT).
But if you have to get by with just the file you already downloaded, you can put it pretty much anywhere you like, as long as that directory is included in the load-path. Manually mucking with the elpa directory is a bad idea, though; put it somewhere else.
Look for comments near the top of the file for any additional instructions; any autoloads, for example, will probably have to be configured separately, and usually completely manually.
This used to be how you always did things in older versions of Emacs, so you should find that the Internet is still practically bulging with guides and tutorials which explain the finer details of this mechanism, if this answer alone isn't sufficient.
When I tried to install flycheck package on emacs24, it show error that let-alist1.0.1 unavailable. But I heard that let-alist is built-in package of emacs25, I wonder is there any work-around for emacs24?
let-alist is available from ELPA. Use
M-x list-packages
to pull up a list of available packages, then search for let-atlist (C-M-s as usual). Then install it. See also here.
Alternatively, you can download it from here and install it manually. ELPA is easier, though.
I'm pretty new to emacs and I'm currently trying to configure it properly for my needs, but I can't make it load web-mode at all.
So, this is what I've done:
Downloaded web-mode.el from GitHub
Made sure the file is located in the correct directory: ~/.emacs.d/web-mode.el
Used the installation instructions from the official page
My .emacs file now looks like this
Issue:
When I'm trying to edit any of the file types specified in the .emacs file, it only runs the default modes. PHP Abbrev for PHP etc... I'm not receiving any error messages and when I'm running --debug-init it does not give any output.
Emacs version: GNU Emacs 23.1.1 (x86_64-redhat-linux-gnu, GTK+ Version 2.18.9) of 2012-03-01 on sl6.fnal.gov
OS: Scientific Linux
Does anyone know how I can troubleshoot this further, or have solved similar issues?
You should let el-get install it for you. El-get is a package manager for emacs. It can install packages from github, emacswiki, elpa, an url, … http://wikemacs.org/index.php/El-get
It's very handy, you can update scripts easily, it manages dependencies, it lets you discover many stuff, you can easily share your config accross machines, etc.
Emacs 24 has package.el or ELPA by default. One can install it on emacs 23, but my experience isn't conclusive so I'd advise sticking with el-get, which is great.
