npm镜像源证书过期的问题解决

Failed to check for updates 问题

错误描述如上

检查完 node,vue,npm 的版本后都没啥问题，尝试更新脚手架

使用指令

#npm脚手架更新

pnpm update -g @vue/cli

出现问题如下：

ERR_PNPM_NO_PKG_MANIFEST

这个是报错类型编号

这个报错是没有找到 package.json 的文件，我当时没仔细看，就尝试重新安装 pnpm

#pnpm更新安装

npm install pnpm -g

出现报错

npm ERR! code CERT_HAS_EXPIRED
npm ERR! errno CERT_HAS_EXPIRED
npm ERR! request to https://registry.npm.taobao.org/pnpm failed, reason: certificate has expired

npm ERR! Log files were not written due to an error writing to the directory: D:\Nodejavascript\node_cache\_logs
npm ERR! You can rerun the command with `--loglevel=verbose` to see the logs in your terminal

在这里已经很明显了，报错提示是 #reason：certificate_has_expired 就是说目前我的镜像网站证书过期了，连淘宝自己提供的镜像源网站都不去管管证书的嘛？？（来自我复盘的吐槽）

当时认为是不是自己的问题，进行 npm 缓存清除操作，

npm缓存清除指令

npm cache clean --force

出现第二个报错

PS D:\front-end\untitled2> npm cache clean --force
npm WARN using --force Recommended protections disabled.
npm ERR! code EPERM
npm ERR! syscall rmdir
npm ERR! path D:\Nodejavascript\node_cache\_cacache\tmp

npm ERR! Log files were not written due to an error writing to the directory: D:\Nodejavascript\node_cache\_logs

其实这个也说的很清楚，Error：EPERM：operation not permitted，rmdir ‘D:\Nodejavascript\node_cache\_cacache\tmp’

就是说没有权限删除，这个问题一般有几种解决思路

权限不足导致删除不了解决方案

• 如果是在C盘的文件遇到权限不足，建议移出C盘，因为C盘的权限是一个迷，很容易出现奇奇怪怪的权限问题
• 如果是在其他盘，直接开管理员权限运行就可以了

之后明白可能是证书和权限的问题，就打算随便执行一下依赖更新操作，检验一下是否可用

#npm依赖更新指令

npm install

然后给我直接报错了 #没有package的Json文件报错

PS D:\front-end\untitled2> npm install
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path D:\front-end\untitled2/package.json
npm ERR! errno -4058
npm ERR! enoent ENOENT: no such file or directory, open 'D:\front-end\untitled2\package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent

npm ERR! Log files were not written due to an error writing to the directory: D:\Nodejavascript\node_cache\_logs
npm ERR! You can rerun the command with `--loglevel=verbose` to see the logs in your terminal
Wrote to D:\front-end\untitled2\package.json:

npm创建基础配资文件

npm init -y

这样就默认创建了一个简单的 package.json 文件

ok! 到此为止，就基本上将边角问题解决了，后续考虑解决问题是否应该切换一个数据源的问题

#npm检查设置远程仓库指令

npm config get registry

得到域名

https://npm.taobao.org

去网上搜，淘宝那个npm 改名了！！！

https://npmmirror.com/

最新的是这个，我真的心情复杂。

设置一下全局镜像源配置就行了，最后完成目的的指令是

npm config set registry=https://npmmirror.com/

如果出现以下这种错误，就是说明镜像源太落后了，不匹配

PS D:\front-end\untitled3> npm install
npm ERR! code ETARGET
npm ERR! notarget No matching version found for @vue/server-renderer@3.4.21.
npm ERR! notarget In most cases you or one of your dependencies are requesting
npm ERR! notarget a package version that doesn't exist.
npm ERR! A complete log of this run can be found in: D:\Nodejavascript\node_cache\_logs\2024-02-29T04_10_05_694Z-debug-0.log
PS D:\front-end\untitled3> npm config set      
npm ERR! code EUSAGE
npm ERR!

主要从这几句话可以看出 notarget No matching version found for @vue/server-renderer@3.4.21

这个是之前我换华为云的镜像服务器之后出现的问题，最后实在不行了，换回了 https://npmmirror.com/ 这个域名

从此，解决 npm 无法使用问题
