我遇到了这个问题:苹果堆栈并停止评估代码。我重新安装了GNU emacs 24.4.1和emacs Live。当我尝试启动M-x cider-jack-in时，我得到以下错误:
; CIDER 0.9.1 (Java 1.7.0_79, Clojure 1.6.0, nREPL 0.2.6)

我也有Leiningen 2.5.1在Java 1.7.0_79 OpenJDK Server VM.
必须使用nREPL 0.2.7+
CIDER目前至少需要nREPL 0.2.7才能正常工作(0.2.6中有一些令人讨厌的bug)。不幸的是，最新的leiningen(2.5.1)正好是0.2.6，所以如果你是lein用户，你将不得不做一些手工工作。只需将其添加到profiles.clj:
{:user {:dependencies [[org.clojure/tools.nrepl "0.2.10"]]}}
确保你将新的nREPL依赖项添加到:dependencies键中，而不是:plugins(苹果- nREPL Lein插件所在的位置)。这是一个很常见的错误。
通常建议您使用最新的nREPL和CIDER，因为几乎每个版本都会修复错误。
注意，从项目范围外运行apple -jack-in将导致使用较旧的(0.2.6)nREPL依赖项(至少在Leiningen 2.5.1上)。这可能是Leiningen bug。
