本地托管 python azure 函数因 M1 而失败

Question

如标题所示，我想在本地使用 VSCode 托管 azure 函数，但出现错误。

Python 版本 3.9.12 (python3).
Azure Functions 核心工具
- 核心工具版本：4.0.4483 提交哈希：N/A（64 位）
- 函数运行时版本：4.1.3.17473

host.json:

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[2.*, 3.0.0)"
  }
}

local.setting.json:

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "python",
    "AzureWebJobsStorage": ""
  }
}

错误信息：

Functions:

        HttpTrigger1: [GET,POST] http://localhost:7071/api/HttpTrigger1

For detailed output, run func with --verbose flag.

Answer 1

从我们这边重现后，我们观察到如果您有 arm64 Python，它将永远无法加载 x86_64 共享库，因此我们需要启用 Rosetta，它工作在按进程级别处理。

要遵循的步骤

检查 iTerm 中的 Rosetta。
安装 homebrew、azure functions 核心工具，并在当前 homebrew 中 python。
然后运行你的 azure 函数。
