fishシェルでanyenvを設定したときにcalled during startupエラーが出る

昨日からfishシェルを使い始めまして、anyenvの設定を ~/.config/fish/config.fish に記述しました。

set -x PATH $HOME/.anyenv/bin $PATH
eval (anyenv init - fish)

そしてfishを起動すると、以下のエラーがでました。

Variables cannot be bracketed. In fish, please use "$PATH".

エラー内容をググってもどうにもならなかったので、config.fishのeval部分をanenv init - fishで表示される内容に変えてみました。

set -x PATH $HOME/.anyenv/bin $PATH

# anyenv init - fish で出てくる内容
source "/home/vagrant/.anyenv/libexec/../completions/anyenv.fish"
function anyenv
  set command $argv[1]
  set -e argv[1]

  command anyenv "$command" $argv
end

set -x GOENV_ROOT "/home/vagrant/.anyenv/envs/goenv"
set -x PATH $PATH "/home/vagrant/.anyenv/envs/goenv/bin"
export PATH="/home/vagrant/.anyenv/envs/goenv/shims:${PATH}"
goenv rehash 2>/dev/null
set -x NDENV_ROOT "/home/vagrant/.anyenv/envs/ndenv"
set -x PATH $PATH "/home/vagrant/.anyenv/envs/ndenv/bin"
export PATH="/home/vagrant/.anyenv/envs/ndenv/shims:${PATH}"

ndenv rehash 2>/dev/null
ndenv() {
  typeset command
  command="$1"
  if [ "$#" -gt 0 ]; then
    shift
  fi

  case "$command" in
  rehash|shell)
    eval "`ndenv "sh-$command" "$@"`";;
  *)
    command ndenv "$command" "$@";;
  esac
}

set -x PYENV_ROOT "/home/vagrant/.anyenv/envs/pyenv"
set -x PATH $PATH "/home/vagrant/.anyenv/envs/pyenv/bin"
setenv PATH '/home/vagrant/.anyenv/envs/pyenv/shims' $PATH
setenv PYENV_SHELL fish
. '/home/vagrant/.anyenv/envs/pyenv/libexec/../completions/pyenv.fish'
command pyenv rehash 2>/dev/null

function pyenv
  set command $argv[1]
  set -e argv[1]

  switch "$command"
  case rehash shell
    . (pyenv "sh-$command" $argv|psub)
  case '*'
    command pyenv "$command" $argv
  end
end

set -x RBENV_ROOT "/home/vagrant/.anyenv/envs/rbenv"
set -x PATH $PATH "/home/vagrant/.anyenv/envs/rbenv/bin"
setenv PATH '/home/vagrant/.anyenv/envs/rbenv/shims' $PATH
setenv RBENV_SHELL fish
source '/home/vagrant/.anyenv/envs/rbenv/libexec/../completions/rbenv.fish'
command rbenv rehash 2>/dev/null
function rbenv
  set command $argv[1]
  set -e argv[1]

  switch "$command"
  case rehash shell
    source (rbenv "sh-$command" $argv|psub)
  case '*'
    command rbenv "$command" $argv
  end
end

こうしてfishを起動しても、また以下のエラーが出ます。どのように対応すれば良いのでしょうか？

'case' builtin not inside of switch block
~/.config/fish/config.fish (line 43):   case "$command" in
                                        ^
from sourcing file ~/.config/fish/config.fish
        called during startup

source: Error while reading file “/home/vagrant/.config/fish/config.fish”

ちなみにanyenvは最新バージョンにアップデートしてあります。
よろしくお願い致します。
