无法使用 pydevd-pycharm 连接到远程调试服务器

Question

我有一个使用 docker 部署的 Django 项目。我想使用Python Remote Debug调试该项目。 这是我如何根据https://www.jetbrains.com/help/pycharm/remote-debugging-with-product.html配置它

之后我启动了调试器，它说：

Use the following code to connect to the debugger:
import pydevd_pycharm
pydevd_pycharm.settrace('0.0.0.0', port=3000, stdoutToServer=True, stderrToServer=True)
Waiting for process connection...

之后我将代码复制到manage.py中的__main__

顺便提一句。 将上面的代码放在某些views中而不是 manage.py dint 帮助

接下来我用 docker 启动了docker-compose up -d proj命令

过了一会儿，我从我的容器中看到日志说：

Could not connect to localhost: 3000

到目前为止，我尝试在 0.0.0.0:8000、localhost:8000 等不同端口上运行调试服务器。 但它没有帮助。 我拿了另一个项目确实需要 docker 才能工作，并且一切正常。 docker 似乎有问题。有什么想法吗？ 我不知道为什么我不工作。

Answer 1

我从未做过，但是看起来'0.0.0.0'部分是运行Pycharm的计算机的地址。

您必须设置机器的IP。 可能也会成功以网络模式“主机”运行容器（因为0.0.0.0是指容器内部）

也许您发现也有用：

• 主机网络上的一个很好的帖子： https : //stackoverflow.com/a/24326540/10962269

• 文档： https : //www.jetbrains.com/help/pycharm/remote-debugging-with-product.html

Answer 2

不确定它是否会对任何人有所帮助，但就我而言，事实证明我忘记了 mac OS 上的 docker 使用 host.docker.internal。

所以我设置：

pydevd_pycharm.settrace('host.docker.internal', port=YOUR_PORT, stdoutToServer=True, stderrToServer=True)

然后单击编辑配置 => python 调试服务器：

host : host.docker.internal
port YOUR_PORT

不要忘记路径映射，（访问您的 docker 并查看在哪里可以找到与根目录完全相同的文件夹，并且不要忘记放置根目录的绝对路径，在我的例子中是这样的 /Users/UserName /Repo/Your_root= /app/src)

它奏效了！

事实证明，端口可以是任何东西，只要它不与现有端口冲突（注意，编辑配置和 settrace 中的端口必须匹配）
