一、问题描述
学习vue数字大屏加载动漫效果时,在项目终端页面输入全局下载指令
npm install -g json-server
问题1、报–4048错误
会报如下错误operation not permitted……errno: -4048code:’EPERM’syscall: ‘mkdir’……The operation was reiected by your operating systemIt’s possible that the file was already in use (by a text editor or antivirus).on that vou lack permissions to access it.
问题2、报ERR_SOCKET_TIMEOUT错误
…This is a problem related to network connectivity.
npm ERR! network In most cases you are behind a proxy or have bad network settings.
npm ERR! network
npm ERR! network If you are behind a proxy, please make sure that the
npm ERR! network ‘proxy’ config is set properly. See: ‘npm help config’…
二、解决步骤
一开始以为是权限问题,本人根据提示路径找到node_modules文件,将文件权限勾选完全控制
但问题仍然存在!!!
1、解决报–4048错误问题方法参考链接1的评论区:
1)找到 C:\Users\{账户}\下的.npmrc 文件,删除.npmrc 文件
2)输入npm cache clean –force指令清除npm缓存:
npm cache clean --force
在使用npm cache clean –force 指令, 若反馈错误,可能是版本过高,可以输入:
npm cache verify
本人在刚刚删除.npmrc的目录下空白地方打开终端, 输入npm cache verify指令通过了:
2、解决报ERR_SOCKET_TIMEOUT错误问题参考链接2
经过以上步骤,当本人再次在项目终端页面输入全局下载指令时,会卡在idealTree: timing idealTree Completed in 32944ms不动,最终报以下错误:
解决方法参考链接2的评论区:
换淘宝镜像源npm config set registry
当本人再再次输入全局下载指令时,通过了!
