npm ERR！错误:EPERM:不允许操作，取消链接 [英] npm ERR! Error: EPERM: operation not permitted, unlink

问题描述

• 操作系统:Windows 10.
• npm版本:6.9.0
• 节点版本:12.4.0

我正在处理一个Expo应用程序. 我想在我的博览会应用程序上安装所有软件包(npm install).但是，发生了错误:

I'm working on an expo application. I would like to install all the packages on my expo application (npm install). But, an error occured :

17254 error [OperationalError: EPERM: operation not permitted, unlink ... 我已经在很多主题上看到了这个错误，但是没有一个答案可以解决我的问题.

17254 error [OperationalError: EPERM: operation not permitted, unlink ... I have seen this error on many subjects, but no one answer to my problem.

我已经尝试过:

1. 以管理员身份启动我的终端机.
2. npm config set safe-perm = true.
3. npm install --no-bin-links
4. npm缓存清除--force

我有一个错误消息的例子:

An exemple of error message that I have :

推荐答案

是否有另一个正在运行的节点实例，也正在使用ReactFabric-dev.js?如果是这样，请终止并重试.另外，请尝试将您的项目移至根目录为"closer"的文件夹. Windows有时会混淆很长的路径.

Is there a another instance of node running, that is also using ReactFabric-dev.js? If so, terminate and retry. Also try to move your project to a folder "closer" to root. Windows sometimes gets confused with very long paths.
