【中文标题】npm WARN saveError EPERM: operation not allowed, rename \'C:\\...\\package.json.3542172463\' -> \'C:\\...\\package.json\'【英文标题】:npm WARN saveError EPERM: operation not permitted, rename 'C:\...\package.json.3542172463' -> 'C:\...\package.json'npm WARN saveError EPERM: operation not allowed, rename 'C:\...\package.json.3542172463' -> 'C:\...\package.json' 【发布时间】:2018-12-28 14:06:05 【问题描述】:环境:
Node: 8.11.2 (installed from nvm)
npm: 5.6.0
OS: Windows Server 2016
AV: Only Windows Defender but it has been disabled
使用的命令:
npm install
npm install grunt
当我运行第一个命令 (npm install) 时,package.json 文件中描述的所有模块都已正确安装。
当我运行第二个命令 (npm install grunt) 时出现错误:
npm WARN saveError EPERM: operation not permitted, rename 'C:\...\package.json.3542172463' -> 'C:\...\package.json'
removed 762 packages in 16.89s
数百个模块已从我的 node_module 目录中删除。
有没有人知道什么会导致这样的问题?
我已经尝试禁用代理,清除 npm 缓存,禁用 AV(只有 Windows Defender),但没有任何结果。
【问题讨论】:
【参考方案1】:更新到最新的 npm 版本 (v6.2.0) 成功了 :)
因为我使用 nvm 在 Windows 上安装 Node.js,所以在更新 npm 时遇到了一些问题,但我找到了以下脚本,由 Adrien Pyke(基于 @arfaWong 的想法)编写并发布于: https://github.com/coreybutler/nvm-windows/issues/300#issuecomment-390293097
