使用 conda 环境在 VS 代码中部署 Azure Functions

Question

在尝试在本地运行我的天蓝色函数时，我在 VS 代码中遇到了一些与 python 设置不一致的问题。我试图避免使用 VS 代码为 azure 函数项目自动设置的“venv”环境，而是使用我制作并安装了所有要求的预先创建的 conda 环境。澄清一下，这是关于本地部署和不是天蓝色的门户。

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:
   ...

.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",
}

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

以防万一，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 调用该函数，返回是HTTP 500 状态，这是由于找不到错误模块而无法import pandas。

如果我在settings.json 中设置"azureFunctions.pythonVenv": ".venv"，函数会在本地部署，一旦触发/调用，它就会返回HTTP 200 状态和正确响应。

那么，这给我带来了一个问题，如果 VS 代码支持用于 azure 功能部署的 conda 环境，如果支持，我在这里缺少什么？

Answer 1

这是我为获得 conda 环境而不是 venv 所做的工作

查看 settings.json 文件。因为我已经安装了 python 扩展并且我已经为这个项目配置了我的解释器，所以我有一个名为 python.pythonPath 的设置。我想使用这个 python 而不是 venv，所以我注释掉了 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",
   ...
}

接下来编辑 tasks.json。注意有一个 pipInstall 任务。我将 widows 命令更改为使用我在设置中定义的python.pythonPath。

旧值类似于"command": "${config:azureFunctions.pythonVenv}/bin/python -m pip install...，新值是"command": "${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": []
        }
    ]
}

对于任何面临类似问题的人，由于 Brig 提供的答案，我最终得到了以下设置：

.vscode\settings.json

{
    // python.pythonPath is machine-dependent, AVOIDING a set value here
    // Local Machine Conda VENV (Define CONDAPATH in Windows Environment)
    "python.condaPath": "${env:CONDAPATH}/Library/bin/conda.bat",
    "python.pythonPath": "${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",

    // Windows pythonPath
    // "python.pythonPath": "src/.venv/Scripts/python.exe",
    // MAC pythonPath
    // "python.pythonPath": "src/.venv/bin/python",  
    
    // Azure Function Stuff
    "azureFunctions.deploySubpath": "src",
    "azureFunctions.scmDoBuildDuringDeployment": true,
    "azureFunctions.projectLanguage": "Python",
    "azureFunctions.projectRuntime": "~3",
    "azureFunctions.preDeployTask": "func: pack --build-native-deps",
    "debug.internalConsoleOptions": "neverOpen",    
}    

.vscode\tasks.json

{
    "tasks": [
        {
            "type": "func",
            "command": "host start",
            "problemMatcher": "$func-watch",
            "isBackground": true,
            "dependsOn": "pipInstall",
            "options": {
                "cwd": "${workspaceFolder}/src"
            }
        },
        {
            "label": "pipInstall",
            "type": "shell",
            "osx": {
                "command": "${config:azureFunctions.pythonVenv}/bin/python -m pip install -r requirements.txt"
            },
            "windows": {
                "command": "${config:azureFunctions.pythonVenv}\\Scripts\\python -m pip install -r requirements.txt"
            },
            "linux": {
                "command": "${config:azureFunctions.pythonVenv}/bin/python -m pip install -r requirements.txt"
            },
            "problemMatcher": [],
            "options": {
                "cwd": "${workspaceFolder}/src"
            }
        }
    ]
}
