使用VS代码实例化运行Azure函数的ECONNREFUSED失败

Question

昨天，我可以使用VS代码运行和调试Azure函数项目。今天，当我点击F5 (“开始调试”)时，会立即出现一个弹出

ECONNREFUSED 127.0.0.1:9091

我认为这是一个网络问题，因为VS代码甚至没有打开显示“执行任务.”的终端。

但是在VS代码中，我可以浏览扩展市场，在终端中运行"pip“。

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": "&&"
    }

这太奇怪了。我反复编辑了我的launch.json，有时它是有效的，有时不是，现在当我保存我的原始launch.json时，配置可以工作。

这种配置工作得很好：

{
    "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"
        }
    ]
}

我不知道怎么回事。

Answer 2

重新安装所有东西。

它起作用了。
