Help us understand the problem. What are the problem?

More than 3 years have passed since last update.

fish 2.6.0 で setenv: Too many arguments エラーが出たとき

kiexで新しいバージョンのElixirをinstallしたところ途中でエラーがでた。

$ kiex install 1.5.1
Downloading elixir version 1.5.1
Installing elixir version 1.5.1
Switched to branch 'master'
...
...

Installed Elixir version 1.5.1
Load with:
           kiex use 1.5.1
or load the elixir environment file with:
   source $HOME/.kiex/elixirs/.elixir-1.5.1.env.fish

$ kiex use 1.5.1
To switch elixir versions for your current shell run:
   source $HOME/.kiex/elixirs/.elixir-1.5.1.env.fish

$ source $HOME/.kiex/elixirs/.elixir-1.5.1.env.fish
setenv: Too many arguments # これです!

調べて見ると setenvset -gxに変更するといいっぽい。

.elixir-1.5.1.env.fish
#'setenv'を'set -gx'に変更

- setenv ELIXIR_VERSION 1.5.1
- setenv PATH $HOME/.kiex/elixirs/elixir-1.5.1/bin $PATH
- setenv MIX_ARCHIVES $HOME/.kiex/mix/archives/elixir-1.5.1
+ set -gx ELIXIR_VERSION 1.5.1
+ set -gx PATH $HOME/.kiex/elixirs/elixir-1.5.1/bin $PATH
+ set -gx MIX_ARCHIVES $HOME/.kiex/mix/archives/elixir-1.5.1

これでしっかり新しいバージョンへ

$ source $HOME/.kiex/elixirs/.elixir-1.5.1.env.fish
$ kiex list

kiex elixirs

   elixir-1.4
   elixir-1.4.4
=* elixir-1.5.1

# => - current
# =* - current && default
#  * - default

[追記]
あとで調べたらkiexの方ですでに修正されてた。普通にkiexをアップデートすればいいっぽい。
Fix fish 2.6 compatibility (https://github.com/taylor/kiex/commit/674c513074a084fd2e006aea84cbaf1157fb8998)

$ kiex selfupdate
