运行 Azure Functions with VS Code instanlty 因 ECONNREFUSED 而失败

Question

昨天我可以 运行 并使用 VS Code 调试我的 Azure Function 项目。今天，当我按下 F5（“开始调试”）时，一个弹出窗口立即出现

connect ECONNREFUSED 127.0.0.1:9091

我认为这是网络问题，因为 VS Code 甚至没有打开显示“正在执行任务 [...]”的终端。

但在 VS Code 中我可以浏览扩展市场，运行 在终端中“pip install”。

这是我的配置：

launch.json

{
        "version": "0.2.0",
        "configurations": [
            {
                "name": "Python: Current file",
                "type": "python",
                "request": "launch",
                "program": "${file}",
                "console": "integratedTerminal"
            },
            {
                "name": "Azure Functions",
                "type": "python",
                "request": "attach",
                "port": 9091,
                "preLaunchTask": "func: host start"
            }
        ]
    }

tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "func",
            "command": "host start",
            "problemMatcher": "$func-python-watch",
            "isBackground": true,
            "dependsOn": "pipInstall",
            "options": {
                "cwd": "${config:azureFunctions.projectSubpath}"
            }
        },
        {
            "label": "pipInstall",
            "type": "shell",
            "command": "${config:python.pythonPath} -m pip install -r requirements.txt",
            "problemMatcher": [],
            "options": {
                "cwd": "${config:azureFunctions.projectSubpath}"
            }
        }

    ]
}

settings.json

{
    "azureFunctions.deploySubpath": "azure-functions\my_project",
    "azureFunctions.projectSubpath": "azure-functions\my_project",
    "azureFunctions.scmDoBuildDuringDeployment": true,
    "azureFunctions.pythonVenv": ".venv",
    "azureFunctions.projectLanguage": "Python",
    "azureFunctions.projectRuntime": "~3",
    
    "debug.internalConsoleOptions": "neverOpen",
    "python.pythonPath": "C:\Users\myself\BigRepo\azure-functions\my_project\.venv\Scripts\python.exe",
    "powershell.codeFormatting.addWhitespaceAroundPipe": true
    //"terminal.integrated.shell.windows": "&&"
    }

Answer 1

这太奇怪了。我来回编辑我的 launch.json，有时它是有效的，有时它不是，现在当我保存我的原始 launch.json 时，配置有效。

此配置工作正常：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Current file",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal"
        },
        {
            "name": "Azure Functions",
            "type": "python",
            "request": "attach",
            "port": 9091,
            "preLaunchTask": "func: host start"
        }
    ]
}

我不确定我明白发生了什么事。
