ritz-nrepl與lein不適用於osx

Question

我想在Emacs中使用ritz-nrepl進行調試。 因為使用lein ritz-nrepl已經失敗， lein ritz-nrepl我還沒有進一步進行Emacs集成。

Exception in thread "main" com.sun.jdi.connect.VMStartException: 
   VM initialization failed for: ...

完整的堆棧跟蹤顯示在帖子的末尾。 我知道這個異常已經存在了一段時間，並且有可能的修復方法，但是這對我的情況沒有幫助：

• 有效的nrepl-ritz設置？
• 無法在Macintosh系統上使用emacs + ritz-nrepl 。

否則，nrepl等。 在我的系統上運行正常。 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看起來像這樣：

{: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]}}}

在lein項目中，我運行lein ritz-nrepl 。 但是，上述異常失敗。 我已經運行了lein ritz-nrepl -l trace但是沒有找到有用的輸出。 我該怎么做才能使它運行？

順便說一句。 我已經用ritz 0.7.1-SNAPSHOT測試了它，但是錯誤仍然存​​在。

我是否缺少明顯的東西？ 任何幫助是極大的贊賞。

干杯!

Answer 1

我知道這個問題很古老，但是我有一個可能的答案，因為我遇到了類似的問題，所以在2019年仍然有用。 問題是您的調試器正在嘗試通過JDI連接到要調試的進程，但是它失敗了。 讓我們看一下“ VM初始化失敗”消息之后的長長的命令行：

 /.../.../java ... -Xrunjdwp:transport=dt_socket,address=London:58846,suspend=y ... clojure.main ...

這是JDI用於啟動JVM的命令行，該JVM反過來運行clojure +要調試的程序。 -Xrunjdwp選項意味着啟動后，JVM將嘗試通過套接字連接到調試器。 確切地說， address=London:58846字符串是調試器進程正在偵聽，等待下級連接的網絡地址和端口。 某些版本的macOS（與Sierra（在我的情況下為Mojave）一起報告）的問題在於macOS無法將主機名（在您的情況下為London ）解析為IP地址，從而阻止JVM連接到調試器。 就我而言，這是因為JDI選擇的主機名是筆記本電腦的本地網絡名 。 但是我不認為這是您的情況，因為上述命令行中的主機名是London ，並且根據Apple的說法，“本地網絡名是您的計算機名稱，並添加了.local ”：由於命令行中的主機名不是London.local ，顯然是在您的情況下，JDI試圖為您的計算機使用另一個非本地網絡名稱。

現在，對於該解決方案，假設您運行要調試程序的London機器與運行調試器的London機器相同（這是很常見的情況）。 您需要做的是“說服” macOS來注冊主機名並將其關聯到您計算機的IP地址。 只是為了記錄在案，在我的情況，在提出解決方法這篇文章是足夠了：我開始的共享服務之一，和MacOS注冊我的電腦的本地網絡名稱。 在您的情況下，我不太了解您的網絡設置，因此只能提出一個丑陋的建議：編輯/etc/hosts文件（您必須是sudo vim或sudo nano ），然后將回送IP地址127.0.0.1映射到您的主機名通過修改行

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並不理想...
