Github Actions macos-12环境下如何强制安装ARM64架构Node.js？

要在macos-12 runner上安装ARM64架构的Node.js，并配合node-gyp编译对应架构的原生模块，你需要做以下关键修改：

1. 指定Node.js的ARM64架构 #

在actions/setup-node步骤中添加architecture: arm64参数，明确要求安装ARM版本的Node.js：

- uses: actions/setup-node@v3
  with:
    node-version: '18'
    architecture: arm64  # 强制安装ARM64版本

2. 配置编译环境适配ARM64 #

由于macos-12 runner默认是x86_64架构，需通过环境变量告知npm和node-gyp以ARM64标准编译模块。在setup-node步骤后添加环境配置：

- name: Set ARM64 build flags
  run: |
    echo "npm_config_arch=arm64" >> $GITHUB_ENV
    echo "npm_config_target_arch=arm64" >> $GITHUB_ENV

修改后的完整Workflow配置 #

name: test-keyring-go
on: [push]
jobs:
  build-native-node-module-on-mac:
    runs-on: macos-12
    environment: dev
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
        with:
          node-version: '18'
          architecture: arm64
      - name: Set ARM64 build flags
        run: |
          echo "npm_config_arch=arm64" >> $GITHUB_ENV
          echo "npm_config_target_arch=arm64" >> $GITHUB_ENV
      - uses: actions/setup-python@v4
        with:
          python-version: '3.10'          
      - uses: actions/setup-go@v3
        with:
          go-version: '1.20.1'      
      - run: npm install --ignore-scripts
      - run: npm run build:go:m1
      - run: npm run build:node:m1
      - run: npm run test
      - run: npm run vitest

验证安装结果 #

可添加一个步骤确认Node.js架构是否为ARM64：

- run: node -p "process.arch"  # 输出应为arm64

完成上述修改后，node-gyp会基于ARM64架构编译原生模块，与你安装的Node.js版本完全适配。
