我正在尝试通过 npm ( npm install -g serverless) 安装无服务器，但出现以下错误：

npm ERR! code EACCES
npm ERR! syscall rename
npm ERR! path /usr/local/lib/node_modules/serverless
npm ERR! dest /usr/local/lib/node_modules/.serverless-Ls3sFIzE
npm ERR! errno -13

有谁知道如何做到这一点而不必切换您正在使用的节点版本？

编辑：当我用 sudo 运行它时，我得到以下输出：

但是，当我尝试运行时，serverless invoke local --function f1我得到zsh: command not found: serverless- 使用 sudo 安装后，我需要做什么才能识别该命令？

你的权限是错误的。一般来说，您不想使用 sudo 从 npm 安装任何东西。

你可以sudo chown yourUser:yourGroup -R /usr/local/lib/node_modules。（如果您在 macOS 上，您的组可能是staff。您可以通过ls -l在主目录中运行并查看与您的用户名相邻的标签来找到您的组）

无论如何，一个简单的替代方案是最佳实践 - 将无服务器框架安装为项目的开发依赖项：

npm i -D serverless

serverless deploy然后你可以运行而不是运行npx serverless deploy。

然后，当您将package.json文件签入版本控制时，其他协作者将使用相同版本的无服务器框架。
