通过 npm 安装无服务器所需的权限

Question

我尝试通过 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
npm ERR! Error: EACCES: permission denied, rename '/usr/local/lib/node_modules/serverless' -> '/usr/local/lib/node_modules/.serverless-Ls3sFIzE'
npm ERR!  [Error: EACCES: permission denied, rename '/usr/local/lib/node_modules/serverless' -> '/usr/local/lib/node_modules/.serverless-Ls3sFIzE'] {
npm ERR!   errno: -13,
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! }
npm ERR! 
npm ERR! The operation was rejected by your operating system.

有谁知道如何做到这一点而无需切换您正在使用的节点版本？

编辑：当我使用 sudo 运行此命令时，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- 在使用 sudo 安装后，我需要做什么才能识别该命令？

你的权限被搞砸了。一般来说，您不想使用 sudo 从 npm 安装任何内容。

你可以sudo chown yourUser:yourGroup -R /usr/local/lib/node_modules。（如果您使用的是 macOS，您的组可能是。您可以通过在主目录中运行并查看用户名旁边的标签来staff找到您的组）ls -l

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

npm i -D serverless

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

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