通过 npm 安装无服务器所需的权限

编程问答 2022-04-23

问题描述

我正在尝试通过 npm (npm install -g serverless) 安装无服务器，但收到以下错误：

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'

有人知道如何在不切换您使用的节点版本的情况下执行此操作吗？

编辑： 当我使用 sudo 运行它时，我得到以下输出：

但是，当我尝试运行 serverless invoke local --function f1 时，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？

解决方法

您的权限已失效。一般来说，你不想用 sudo 从 npm 安装任何东西。

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

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

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

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