python 使用conda环境在VS代码中部署Azure Functions

我在尝试本地运行我的Azure函数时，在VS代码中的Python设置有一点不一致的问题。我试图避免使用VS代码自动为Azure函数项目设置的“venv”环境，而是使用我预先创建的conda环境，并安装了所有要求。只是为了澄清，这是关于本地部署而不是Azure门户。

myfunc__init__.py：

import json
import logging
import time
import azure.functions as func
import pandas as pd                    # Import Error happens here!
def main(req: func.HttpRequest) -> func.HttpResponse:
   ...

字符串

.vscode\Settings.json：

{
  // Local Machine Conda VENV (Define CONDAPATH in Windows Environment)
  "python.condaPath": "%CONDAPATH%",
  "python.pythonPath": "%CONDAPATH%\\envs\\azure\\python.exe",
  "azureFunctions.pythonVenv": "%CONDAPATH%\\envs\\azure",
  // Created Local VENV by VS Code (pythonPath is difference for MAC vs Windows)
  //"azureFunctions.pythonVenv": ".venv",
  // Azure Function Stuff
  "azureFunctions.deploySubpath": ".",
  "azureFunctions.scmDoBuildDuringDeployment": true,
  "azureFunctions.projectLanguage": "Python",
  "azureFunctions.projectRuntime": "~2",
  "azureFunctions.preDeployTask": "func: pack --build-native-deps",
  "debug.internalConsoleOptions": "neverOpen",
}

型

**注意：**如果我用conda的实际绝对路径替换%CONDAPATH%，问题仍然存在。

在需要时，launch.json配置如下：

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Linux_PyFunc",
      "type": "python",
      "request": "attach",
      "port": 9091,
      "preLaunchTask": "func: host start"
    }
  ]
}

当VS Code运行函数时，部署完成，没有问题，并生成本地链接。一旦我通过Postman调用函数，返回的是HTTP 500状态，这是由于无法import pandas与错误模块未找到。
如果我在settings.json中设置"azureFunctions.pythonVenv": ".venv"，函数将在本地部署，一旦被触发/调用，它将返回HTTP 200状态和正确的响应。
所以，这给我带来了一个问题，如果VS代码支持Azure函数部署的conda环境，如果是这样，我在这里错过了什么？

这是我所做的，以获得康达环境，而不是venv
查看settings.json文件。因为我已经安装了python扩展，并且已经为这个项目配置了解释器，所以我有一个名为python.pythonPath的设置。我想使用这个python而不是venv，所以我注解掉了venv设置。

{
    "azureFunctions.deploySubpath": "./functions/",
    "azureFunctions.scmDoBuildDuringDeployment": true,
    // "azureFunctions.pythonVenv": "../.venv", // Ignore not going to use
    "azureFunctions.projectLanguage": "Python",
    ...
    "python.pythonPath": "C:\\path\\to\\Anaconda3\\envs\\myenviron\\python.exe",
   ...
}

字符串
接下来编辑tasks.json。注意有一个pipInstall任务。我将widows命令更改为使用在设置中定义的python.pythonPath。
旧值类似于"command": "${config:azureFunctions.pythonVenv}/bin/python -m pip install...，新值为"command": "${config:python.pythonPath} -m pip install...

{
    "version": "2.0.0",
    "tasks": [
        ...
        {
            "label": "pipInstall",
            "type": "shell",
            "osx": {
                "command": "${config:python.pythonPath} -m pip install -r ${config:azureFunctions.deploySubpath}/requirements.txt"
            },
            "windows": {
                "command": "${config:python.pythonPath} -m pip install -r ${config:azureFunctions.deploySubpath}\\requirements.txt"
            },
            "linux": {
                "command": "${config:python.pythonPath} -m pip install -r ${config:azureFunctions.deploySubpath}/requirements.txt"
            },
            "problemMatcher": []
        }
    ]
}

对于任何人面临类似的问题，我已经结束了以下设置感谢布里格提供的答案：

    "python.pythonPath": "${env:CONDAPATH}/envs/azure/python.exe",
    // Needs `pyvenv.cfg` present in venv path?
    // "azureFunctions.pythonVenv": "${env:CONDAPATH}/envs/azure",
    // Created Local VENV by VS Code (pythonPath is difference for MAC vs Windows)
    "azureFunctions.pythonVenv": ".venv",
