我想在Emacs中使用ritz-nrepl进行调试。因为lein ritz-nrepl已经失败了，所以我没有进一步了解Emacs集成。
Exception in thread "main" com.sun.jdi.connect.VMStartException:
VM initialization failed for: ...
完整的堆栈跟踪显示在帖子的末尾。我知道这个例外已经存在了一段时间，并且有可能的修复，但这对我的情况没有帮助：
否则，nrepl等。在我的系统上工作得很好。我正在使用clojure 1.5.1
$> lein version
Leiningen 2.2.0 on Java 1.7.0_25 Java HotSpot(TM) 64-Bit Server VM
我的~/.lein/profiles.clj看起来像这样：
{:user
{:plugins [[lein-ritz "0.7.0"]]
:dependencies [[nrepl-inspect "0.3.0"]
[org.clojure/tools.trace "0.7.5"]
[ritz/ritz-nrepl-middleware "0.7.0"]
[ritz/ritz-debugger "0.7.0"]
[clojure-complete "0.2.3"]]
:repl-options {:nrepl-middleware
[ritz.nrepl.middleware.javadoc/wrap-javadoc
ritz.nrepl.middleware.simple-complete/wrap-simple-complete
inspector.middleware/wrap-inspect]}}}
从lein项目中我运行lein ritz-nrepl。但是由于上述异常，这失败了。我运行lein ritz-nrepl -l trace但没有找到有用的输出。我该怎么做才能让它运转起来？
BTW。我用ritz 0.7.1-SNAPSHOT对此进行了测试，但错误仍然存在。
我错过了一些明显的东西吗任何帮助是极大的赞赏。
干杯!

我知道这个问题很古老，但我有一个可能的答案，这在2019年仍然有用，因为我有类似的问题。问题是你的调试器试图通过JDI连接到要调试的进程但它失败了。让我们看看“VM初始化失败”消息后的长命令行：
/.../.../java ... -Xrunjdwp:transport=dt_socket,address=London:58846,suspend=y ... clojure.main ...
这是JDI用于启动JVM的命令行，该JVM依次运行clojure +您要调试的程序。 -Xrunjdwp选项意味着在启动后，JVM将尝试通过套接字连接到调试器。 address=London:58846字符串恰好是调试器进程正在侦听的网络地址和端口，等待连接较差。某些版本的macOS（在Sierra和我的情况下，Mojave报告）的问题是macOS无法将主机名（在您的情况下为London）解析为IP地址，从而阻止JVM连接到调试器。在我的情况下，这是因为JDI正在挑选的主机名是我的笔记本电脑的local network name。但我不认为这是你的情况，因为上面命令行中的主机名是London，并且根据Apple“本地网络名称是添加了.local的计算机名称”：由于命令行中的主机名不是London.local，显然在您的情况下，JDI正在尝试为您的计算机使用另一个非本地网络名称。
现在为解决方案，假设您运行调试程序的London机器与运行调试器的位置相同（这是很常见的情况）。您需要做的是“说服”macOS注册主机名并将其与您的计算机的IP地址相关联。仅仅为了记录，在我的情况下，在this post提出的解决方法就足够了：我启动了一个共享服务，macOS注册了我的计算机的本地网络名称。在你的情况下，我不太了解你的网络设置，我只能建议一个丑陋的黑客：编辑/etc/hosts文件（你必须sudo vim或sudo nano）并通过修改行将环回IP地址127.0.0.1映射到你的主机名
127.0.0.1 localhost
至
127.0.0.1 localhost London
我知道在2019年不得不修改/etc/hosts不太理想......
