如何升级leiningen的nrepl版本? [英] How to upgrade nrepl version of leiningen?

问题描述

我正在使用 leiningen 和 emacs + cider 进行 clojure 开发.几天前，在我通过 emacs 包管理器升级 cider 后，当我运行 Mx cider-connect 或 Mx cider- 时，我收到以下警告消息插入.

I'm using leiningen and emacs + cider for clojure development. A few days ago, after I upgrade cider through emacs package manager, I'm getting the following warning message when I run M-x cider-connect or M-x cider-jack-in.

; CIDER 0.9.0snapshot (package: 20150222.137) (Java 1.8.0_31, Clojure 1.6.0, nREPL 0.2.6)
WARNING: CIDER requires nREPL 0.2.7 to work properly

警告信息明确指出我必须将 nrepl 升级到 0.2.7，但是，我不知道如何进行.

The warning message clearly says that I have to upgrade nrepl to 0.2.7, however, I don't know how.

我通过 brew 安装了 leiningen，它使用 nrepl 0.2.6.

I installed leiningen via brew, and it uses nrepl 0.2.6.

$ lein repl

推荐答案

我刚刚遇到了这个问题，我通过添加对较新版本 tools.nrepl 的显式依赖来解决它profiles.clj.我的~/.lein/profiles.clj:

I've just had this problem, and I solved it by adding an explicit dependency on the newer version of tools.nrepl to profiles.clj. My ~/.lein/profiles.clj:

{:repl {:plugins [[cider/cider-nrepl "0.9.0-SNAPSHOT"]]
        :dependencies [[org.clojure/tools.nrepl "0.2.7"]]}}

不知道这是最好的还是官方的方式，不过.

No idea whether that's the best or official way to do it, tho'.
