I was trying to install dash using elpa but failed.
I can't understand why it shows dash[no match]
by following M-x package-install RET dash RET
as in the snapshot. can anyone let me know why? Thank you!
I also tried list-package and dash does not show up in the available list. I am pretty sure I installed dash this way earlier and removed it later.
I described the package-archives variable and it's as below:
package-archives is a variable defined in ‘package.el’.
Its value is
(("org" . "http://orgmode.org/elpa/")
("gnu" . "https://elpa.gnu.org/packages/")
("melpa" . "https://melpa.milkbox.net/packages/"))
Original value was
(("gnu" . "https://elpa.gnu.org/packages/"))
