一、报错信息

permissions of the file and its containing directories, or try running npm ERR!

npm ERR! code EPERM
npm ERR! syscall unlink
npm ERR! path D:\BanGong\eclipse\WorkSpeace\JooLun-wx\joolun-wx-ui\node_modules\.staging\ant-design-vue-a7f0335c\dist\antd-with-locales.min.js
npm ERR! errno -4048
npm ERR! Error: EPERM: operation not permitted, unlink 'D:\BanGong\eclipse\WorkSpeace\JooLun-wx\joolun-wx-ui\node_modules\.staging\ant-design-vue-a7f0335c\dist\antd-with-locales.min.js'
npm ERR!  [OperationalError: EPERM: operation not permitted, unlink 'D:\BanGong\eclipse\WorkSpeace\JooLun-wx\joolun-wx-ui\node_modules\.staging\ant-design-vue-a7f0335c\dist\antd-with-lo
cales.min.js'] {
npm ERR!   cause: [Error: EPERM: operation not permitted, unlink 'D:\BanGong\eclipse\WorkSpeace\JooLun-wx\joolun-wx-ui\node_modules\.staging\ant-design-vue-a7f0335c\dist\antd-with-local
es.min.js'] {
npm ERR!     errno: -4048,
npm ERR!     code: 'EPERM',
npm ERR!     syscall: 'unlink',
npm ERR!     path: 'D:\\BanGong\\eclipse\\WorkSpeace\\JooLun-wx\\joolun-wx-ui\\node_modules\\.staging\\ant-design-vue-a7f0335c\\dist\\antd-with-locales.min.js'
npm ERR!   },
npm ERR!   errno: -4048,
npm ERR!   code: 'EPERM',
npm ERR!   syscall: 'unlink',
npm ERR!   path: 'D:\\BanGong\\eclipse\\WorkSpeace\\JooLun-wx\\joolun-wx-ui\\node_modules\\.staging\\ant-design-vue-a7f0335c\\dist\\antd-with-locales.min.js',
npm ERR!   parent: '@smallwei/avue'
npm ERR! }
npm ERR!
npm ERR! The operation was rejected by your operating system.
npm ERR! It's possible that the file was already in use (by a text editor or antivirus),
npm ERR! or that you lack permissions to access it.
npm ERR!
npm ERR! If you believe this might be a permissions issue, please double-check the
npm ERR! permissions of the file and its containing directories, or try running
npm ERR! the command again as root/Administrator.

npm ERR! A complete log of this run can be found in:
npm ERR!     D:\BanGong\npm\node_cache\_logs\2022-06-01T01_48_26_519Z-debug.log

二、解决方法

1. 点击Windows按键，搜索命令提示符，如图：（一定要点击以管理员身份运行）
   

2. 我项目在d盘输入 d: 然后一步一步找到项目路径的前台项目下（如图）

3. 

4. 输入：npm install -g cnpm --registry=https://registry.npm.taobao.org --verbose

5. 等待下载，结果如图：
   

注：如还是不能npm run dev按我的方法走一遍，删除node_modules文件重新走一遍

1.npm install --registry=https://registry.npm.taobao.org

2. 如提示‘vue-cli-service‘ 不是内部或外部命令，也不是可运行的程序 或批处理文件。执行：
npm install -g @vue/cli-service

3,安装vue，输入命令

npm install vue

4,安装vue-cli，输入命令

npm install --global vue-cli

5.(如报这个错A complete log if this run can be found in)执行全局更新
npm install npm -g
或者用淘宝镜像命令
cnpm install npm -g

查看node与npm版本是否匹配

指定npm版本命令：npm install -g npm@6.14.5

如果报这个错，node版本过低，下载个nvm，之后安装nvm install 14.1.0

npm ERR! vote@1.0.0 dev: `vite`

问题记录
报这个错，npm install --forace

三、状态码为：9 报错信息

node: --openssl-legacy-provider is not allowed in NODE_OPTIONS
npm ERR! code ELIFECYCLE
npm ERR! errno 9
npm ERR! ruoyi@3.8.6 dev: `set NODE_OPTIONS=--openssl-legacy-provider & vue-cli-service serve`
npm ERR! Exit status 9
npm ERR!
npm ERR! Failed at the ruoyi@3.8.6 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     D:\BanGong\npm\node_cache\_logs\2023-12-08T01_42_13_159Z-debug.log

解决方法

1. node版本过低，使用最新版本完美解决

2. 我上一版本使用的是14，升级到了最新的20

3. 下载最新版本：
   nvm install 20.10.0

4. 通过nvm切换版本：
   nvm use 20.10.0

5. nvm list查看是否切换成功
