首页 > 解决方案 > npm WARN saveError EPERM: operation not allowed, rename 'C:\...\package.json.3542172463' -> 'C:\...\package.json'

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

并且从我的 node_module 目录中删除了数百个模块。

有谁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。

解决方案


更新到最新的 npm 版本(v6.2.0)就可以了:)

因为我使用 nvm 在 Windows 上安装 Node.js 我在更新 npm 时遇到了一些问题,但我找到了以下脚本,由 Adrien Pyke 编写(基于 @arfaWong 的想法)并发布在: https://github。 com/coreybutler/nvm-windows/issues/300#issuecomment-390293097

@echo off
SETLOCAL EnableDelayedExpansion

if [%1] == [] (
    echo Pass in the version you would like to install, or "latest" to install the latest npm version.
) else (
    set wanted_version=%1

    if "!wanted_version!" == "latest" (
        for /f %%i in ('npm show npm version') do set wanted_version=%%i
    )

    for /f %%i in ('npm -g -v') do set cur_version=%%i

    if "!cur_version!" == "!wanted_version!" (
        echo Already on npm version !wanted_version!.
    ) else (
        echo Updating to !wanted_version!...

        set node_path=!PROGRAMFILES!\nodejs

        rename "!node_path!\npm" npm2
        rename "!node_path!\npm.cmd" npm2.cmd
        rename "!node_path!\node_modules\npm" npm2
        node "!node_path!\node_modules\npm2\bin\npm-cli.js" i npm@!wanted_version! -g

        for /f %%i in ('npm -g -v') do set new_version=%%i

        echo New version installed is !new_version!

        if "!new_version!" == "!wanted_version!" (
            echo Successfully updated to !wanted_version!. Cleaning up backups...
            del "!node_path!\npm2"
            del "!node_path!\npm2.cmd"
            @RD /S /Q "!node_path!\node_modules\npm2"
            echo Update complete.
        ) else (
            echo Something went wrong. Rolling back.
            if exist "!node_path!\npm" (
                del "!node_path!\npm"
            )
            if exist "!node_path!\npm.cmd" (
                del "!node_path!\npm.cmd"
            )
            if exist "!node_path!\node_modules\npm" (
                @RD /S /Q "!node_path!\node_modules\npm"
            )
            rename "!node_path!\npm2" npm
            rename "!node_path!\npm2.cmd" npm.cmd
            rename "!node_path!\node_modules\npm2" npm
        )
    )
)
