npm config set prefix /usr/local

After running that command, When trying to run any npm commands on Windows OS I keep getting the below.

运行该命令后，尝试在 Windows 操作系统上运行任何 npm 命令时，我不断收到以下信息。

Error: EPERM: operation not permitted, mkdir 'C:\Program Files (x86)\Git\local'
at Error (native)

Have deleted all files from

已经删除了所有文件

C:\Users\<your username>\.config\configstore\

It did not work.

这没用。

Any suggestion ?

有什么建议吗？

Running this command was my mistake.

运行这个命令是我的错误。

npm config set prefix /usr/local

npm 配置设置前缀 /usr/local

Path /usr/localis not for windows. This command changed the prefix variable at 'C:\Program Files (x86)\Git\local'

路径/usr/local不适用于 Windows。此命令更改了前缀变量'C:\Program Files (x86)\Git\local'

To access and make a change to this directory I need to run my cmd as administrator.

要访问并更改此目录，我需要以管理员身份运行我的 cmd。

So I did:

所以我做了：

1. Run cmd as administrator
2. Run npm config edit(You will get notepad editor)
3. Change prefixvariable to C:\Users\<User Name>\AppData\Roaming\npm

1. 以管理员身份运行cmd
2. 运行npm config edit（您将获得记事本编辑器）
3. 将prefix变量更改为C:\Users\<User Name>\AppData\Roaming\npm

Then npm startworks in a normal console.

然后npm start在普通控制台中工作。

This is occurring because windows is not giving permission to the user to create a folder inside system drive. To solve this:

发生这种情况是因为 Windows 没有授予用户在系统驱动器内创建文件夹的权限。要解决这个问题：

Right Click

右键点击

The Folder > Properties> SecurityTab

文件夹 >属性>安全选项卡

Click on Editto change Permissions > Select the user and give Full Controlto that user.

单击编辑以更改权限 > 选择用户并将完全控制权授予该用户。

Sometimes, all that's required is to stop the dev server before installing/updating packages.

有时，所需要做的就是在安装/更新软件包之前停止开发服务器。

In my case, I was facing this error because my directory and its file were opened in my editor (VS code) while I was running npm install. I solved the issue by closing my editor and running npm installthrough the command line.

就我而言，我遇到了这个错误，因为我的目录及其文件是在我运行时在我的编辑器（VS 代码）中打开的npm install。我通过关闭编辑器并运行npm install命令行解决了这个问题。

I had the same problem, after updating npm. Solved it by re-installing latest npm again with:

更新 npm 后，我遇到了同样的问题。通过重新安装最新的 npm 解决了这个问题：

npm i -g npm

but this time with cmd running in administrating mode.

但这次 cmd 在管理模式下运行。

i did all this because i suspected there was an issue with the update, mostly some missing files.

我这样做是因为我怀疑更新存在问题，主要是一些丢失的文件。

for me it was an issue of altering existing folders in node_module, so i nuked the whole folder and run npm install again. it works with no errors after that

对我来说，这是更改 node_module 中现有文件夹的问题，所以我取消了整个文件夹并再次运行 npm install。在那之后它没有错误
