执行python的dap-debug，在compile时卡住

Emacs-general

最近在windows下lsp-mode编写python用得很愉快，各项补全，doc功能都没有任何delay的问题。

唯独dap-debug一直没有成功，我的dap-mode设定如下：

(use-package dap-mode
   after lsp-mode
  :commands dap-debug
  :init (dap-mode 1)
        (dap-ui-mode 1)
  :config  (require 'dap-python))

执行dap-debug后在compilation会显示

-*- mode: compilation; default-directory: "d:/gui/" -*-
Compilation started at Sun Jul 28 22:15:06

c:/Python37/python.exe -m ptvsd --wait --host localhost --port 32000 d:/gui/Market.py

接著就一直停住，我试过在不中断compile时直接再执行dap-debug，结果是一样的。

目前所用的ptvsd版本是最新的4.3.0，也试过其他版本的ptvsd，也是一样结果。 并且显示如下的message:

Failed to connect to localhost:32000 with error message make client process failed: Connection refused, :name, *connection-test*, :buffer, nil, :host, localhost, :service, 32000, :nowait, nil, :tls-parameters, nil

请教各位大神，此问题如何解？

遇到了同样的问题。

3

Linux下使用没有遇到问题，是否跟防火墙之类的有关？

4

试过关闭防火墙没用，看似是dap-server没有启动，所以一开始就连线不到

5

看看dap和ptvsd的log

6

试过在环境变数中加了 PTVSD_LOG_DIR， 但没有任何log档案产生。

试了中断compilation，显示下面的讯息，看起来是IPC的问题，不知如何处理

大佬，你问题解决了吗，我在windows10 ubuntu子系统也遇到了这个问题。有人个在github提出了这个问题https://github.com/emacs-lsp/lsp-mode/issues/975

8

你这个问题解决了吗

9

我在MacOS中，遇到的是compile 成功后，dap就立即终止了。。。有人遇到这个问题么？

10

沒有解決，試過很多方法，所有ptvsd版本，都沒法子，放棄了

11

我现在调试看代码都，只能用vscode，我之前在ubuntu系统是正常的，最近迁回windows10子系统就不能debug了，哎

13

在MacOS上，已经可以用了，后来也没有怎么处理；不过调试起来，函数step in 内部，和想到的不太一致； 我后来会经常用realgud，感觉界面粗糙了一点，但功能用起来刚刚够。
