如何解决npm错误“ npm ERR！ errno 9009”在dev：“ lite-server”

问题描述

因此，我开始学习引导程序，为此，我必须安装和配置node＆npm才能运行lite-server，我已经创建了.json文件，并使用命令“ npm install lite-server安装了lite服务器- -save-dev”，然后在json文件的脚本中添加“ dev”：“ lite-server”，然后尝试运行命令“ npm run dev”，则出现此错误。

解决方法

此错误特定于nodejs环境，您需要执行一些步骤来解决此问题，例如

第1步-清理npm缓存，npm缓存会因损坏问题而自我修复，并且保证从缓存中提取的数据是有效的

npm cache clean --force

第2步-删除node_modules和程序包锁定JSON，通过删除它会从您的项目中删除node_modules文件夹。

rm -rf node_modules package-lock.json

第3步-重新安装依赖项

npm install

第4步-运行程序

npm run dev
