windows系统下使用node.js在使用npm安装tyarn时报错的解决方法,
下列方法适用大部分npm下载权限不足问题

提供几种如下解决方案
-
使用win+x,选择命令提示符(管理员),在里面运行命令就好了。
-
如果自己本身就是管理员权限,因而无用,最后症结是缓存问题导致
需要删除npmrc文件。
强调:不是nodejs安装目录npm模块下的那个npmrc文件
而是在C:Users{账户}下的.npmrc文件..
- 当然也有说用命令清除缓存的,我自己试了下没成功,上面删除文件来的更加直接彻底,关键是见效。
直接用命令清理就行,控制台输入:
npm cache clean --force
