尽管有这些错误，我该如何安装 elm-repl？

Question

我对 elm 和 web 开发总体上是全新的。我正在阅读指南 here. I installed Sublime Text and the elm compiler. I'd like to use a REPL to play around with things easily. I tried installing it through the instructions here，其中我运行这个：

cabal update ; cabal install elm-repl

但是我得到这个错误：

如果您已经安装了 Elm 编译器，那么您已经有了 REPL。尝试在 shell 中输入 elm repl。请注意，此命令中没有连字符。

安装单独 REPL 所遵循的说明早已过时。

尽管有这些错误，我该如何安装 elm-repl？
