Kill whatever process is locking your files

杀死任何锁定文件的进程

It seems like this kind of error can be caused by a file permissions lock - I experienced something very similar (the same ERRNO: -4048) when installing whatwg-fetch.

似乎这种错误可能是由文件权限锁定引起的 - 我在安装whatwg-fetch.

I found that a Visual Studio instance I had open at the same time was acquiring all kinds of files which it didn't need. Once I closed that down, the install worked perfectly.

我发现我同时打开的一个 Visual Studio 实例正在获取它不需要的各种文件。一旦我关闭它，安装工作完美。

This may be a quickly-checked possible cause to eliminate before moving on to more drastic measures...

在采取更严厉的措施之前，这可能是一个快速检查的可能原因以消除...

I was having the same problem and I found the following solution:

我遇到了同样的问题，我找到了以下解决方案：

1. remove both of

   • %ProgramFiles%\nodejs\npm
   • %ProgramFiles%\nodejs\npm.cmd

2. Go into %ProgramFiles%\nodejs\node_modules\npm and copy the file named npmrc in the new npm folder, which should be %appdata%\npm\node_modules\npm. This will tell the new npm where the global installed packages are.

3. Restart Windows and it worked.

1. 删除两者

   • %ProgramFiles%\nodejs\npm
   • %ProgramFiles%\nodejs\npm.cmd

2. 进入 %ProgramFiles%\nodejs\node_modules\npm 并将名为 npmrc 的文件复制到新的 npm 文件夹中，该文件夹应该是 %appdata%\npm\node_modules\npm。这将告诉新的 npm 全局安装的包在哪里。

3. 重新启动 Windows，它起作用了。

It seems that this error can manifest for more than one reason, so there probably won't be a single fix which works for everyone.

似乎此错误可能因多个原因而出现，因此可能不会有一个适用于所有人的修复程序。

However, concurrency issues often are the cause of the failing installs. According to the accumulated wisdom in one of the related npm issue threads, which has received nearly 180 comments so far, the underlying problem is

但是，并发问题通常是安装失败的原因。根据其中一个相关 npm 问题线程中积累的智慧，迄今为止已收到近 180 条评论，潜在的问题是

a race condition between asynchronous I/O operations accessing the same files on the harddisk. You can certainly influence it by cleaning up the harddisk e.g. with "npm cache verify" or moving the project to a SSD, but this does not solve the root cause of the problem.

访问硬盘上相同文件的异步 I/O 操作之间的竞争条件。您当然可以通过清理硬盘来影响它，例如使用“npm cache verify”或将项目移动到 SSD，但这并不能解决问题的根本原因。

Likewise, closing the IDE or disabling the virus scanner works sometimes, for some people, but does not really fix the problem for good if concurrency issues are behind it.

同样，关闭 IDE 或禁用病毒扫描程序有时对某些人有效，但如果并发问题背后存在，则并不能真正解决问题。

A patch has landed in npm 5.6.0. According to initial reports, it seems to do the trick. So if your npm --versionis lower, update to 5.6.0 (or whatever the current version is when you read this):

补丁已登陆 npm 5.6.0。根据初步报告，它似乎奏效了。因此，如果您npm --version的版本较低，请更新到 5.6.0（或阅读本文时的任何当前版本）：

npm uninstall -g npm
npm install -g [email protected]

as suggested here.

正如这里所建议的。

If that doesn't help, then perhaps a file lock isthe true cause. And closing the IDE, or disabling the virus scanner temporarily, or some similar action is indeed the way to go, as @Oly has said above.

如果这没有帮助，那么文件锁定可能是真正的原因。关闭 IDE，或者暂时禁用病毒扫描程序，或者一些类似的操作确实是可行的方法，正如@Oly上面所说的那样。

For me @Oly's solution worked, I'll just add for Angular folks that it was ng serve -othat had locked the files. Yep - don't run npm installwhile ng serveis running for the project.

对我来说，@Oly 的解决方案奏效了，我会为 Angular 的人补充一点，就是ng serve -o它锁定了文件。是的 -在项目运行npm install时不要运行ng serve。

Do the followings. This might be permissionissue.

做到以下几点。这可能是权限问题。

1. Uninstall all antivirus program and restart system
2. Install yarn
3. Delete package.lock.json and node_modules folder (if any)
4. Clear the cache (npm cache clean --force)
5. Close VS code or other code editor tool (If opened)
6. now run yarn install

1. 卸载所有杀毒程序并重启系统
2. 安装纱线
3. 删除 package.lock.json 和 node_modules 文件夹（如果有）
4. 清除缓存（npm cache clean --force）
5. 关闭 VS 代码或其他代码编辑器工具（如果打开）
6. 现在运行 yarn install

This should resolve the issue.

这应该可以解决问题。
