Question

我正在尝试创建一个Node Restful API服务，但是npm在启动时给了我一个错误。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启动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

相反它应该从npm开始并将结果显示为

todo list启动RESTful API服务器：3000

请指导我如何克服这一点。

Answer 1

以下步骤对我有用：

从控制面板卸载Node.js
转到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：）

NPM在启动时显示无法找到模块＆＃39; safe-buffer＆＃39;
