NPM 启动时显示找不到模块 'safe-buffer'

Question

我正在尝试创建一个节点 Restful API 服务，但是 npm 在启动时给我一个错误。在命令提示符下，我输入了以下内容：

D:\xampp\htdocs\todoListApi>npm run start

todolistapi@1.0.0 start D:\xampp\htdocs\todoListApi

nodemon server.js

显示以下错误

[nodemon] 1.17.3
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `node server.js`
internal/modules/cjs/loader.js:550
    throw err;
    ^

相反，它应该启动 npm 并将结果显示为

todo list RESTful API server started on: 3000

请指导我如何克服这个问题。

Answer 1

以下步骤对我有用：

从控制面板卸载 Node.js
去C:/Users/Admin/AppData/Roaming
手动删除 npm 和 npm-cache

再次尝试安装 node.js。

Answer 2

尝试使用 npm cache clean --force，如果仍然无效，请尝试完全重新安装 NPM/Node :)
