我有一些問題,建立我的OCaml的環境設置,和我下面這個頁面:OPAM和OCaml的安裝
https://github.com/realworldocaml/book/wiki/Installation-Instructions
不過,我有一些問題,我解決不了。我在macOS 10.12.5上使用zsh。
Brew安裝opam時沒有錯誤或警告。我相信我的問題是環境變量(??)不同步。這裏有一些輸出,當我運行一些建議的命令:
OPAM開關:
-- -- 4.04.2 Official 4.04.2 release

You should run: eval `opam config env`

對於這個問題的目的,我展示了我的安裝基地的嘗試,但最終想安裝核心,utop,綠洲等...任何幫助,非常感謝!
編輯:當我應該使用反引號(`)時,我使用了撇號(')。我想,一個沒有經驗的shell用戶的證據......
您是否嘗試先運行「opam update」和「opam upgrade」? – soupault
是的,只是試過這些並再次運行eval。仍然有像以前一樣的問題 –
