Mac M2芯片运行Mongo run-rs报错Unknown system error -86求助

我在搭载M2芯片的Mac设备上运行run-rs -v 5.0.13 --shell时遇到错误，此前在Intel芯片设备上使用相同版本的Node.js（v16.13.1）可正常运行，错误信息如下：

% run-rs -v 5.0.13 --shell

解决思路 #

• 错误根源：System error -86是Apple Silicon芯片的架构不兼容错误，run-rs下载的MongoDB 5.0.13是Intel(x86_64)架构版本，无法在ARM64的M2芯片上直接运行。

• 方案1：Rosetta 2转译运行

  1. 未安装Rosetta 2时先执行：softwareupdate --install-rosetta
  2. 切换到x86架构shell：arch -x86_64 zsh
  3. 重新执行run-rs命令：run-rs -v 5.0.13 --shell

• 方案2：升级run-rs与MongoDB版本

  1. 卸载旧版run-rs：npm uninstall -g run-rs
  2. 安装最新版run-rs：npm install -g run-rs
  3. 使用支持ARM64的MongoDB版本运行，例如：run-rs -v 5.0.14 --shell（5.0.14及以上的5.x版本，或6.x/7.x全系列均支持Apple Silicon）

• 方案3：手动替换ARM架构mongod文件

  1. 下载对应ARM64架构的5.0.x版本mongod二进制文件
  2. 替换run-rs目录下的mongod：将下载文件替换到/Users/mattkuhns/.nvm/versions/node/v16.13.1/lib/node_modules/run-rs/5.0.13/路径下
  3. 赋予执行权限：chmod +x /Users/mattkuhns/.nvm/versions/node/v16.13.1/lib/node_modules/run-rs/5.0.13/mongod
  4. 重新执行run-rs命令
