Kill whatever process is locking your files

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时经历了非常相似的事情（相同的ERRNO：-4048）。

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...

这可能是一个快速检查的可能原因，在采取更激烈的措施之前消除...

if you still have troubles with this error and maybe you upgrade the node version to 5.4 > ... that version presents an error. here the solution that basically consist in downgrade node version

如果您仍然遇到此错误的麻烦，并且可能将节点版本升级到5.4> ...该版本出现错误。这里的解决方案基本上包括降级节点版本

In Windows will be:

在Windows中将是：

npm install -g npm@5.3

That's works for me.

这对我有用。

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

   删除两者

   • %ProgramFiles%\nodejs\npm
   • 的％ProgramFiles％\的NodeJS \ NPM
   • %ProgramFiles%\nodejs\npm.cmd
   • 的％ProgramFiles％\的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.

   进入％ProgramFiles％\ nodejs \ node_modules \ npm并在新的npm文件夹中复制名为npmrc的文件，该文件夹应为％appdata％\ npm \ node_modules \ npm。这将告诉新的npm全局安装包的位置。

3. Restart Windows and it worked.

   重新启动Windows，它工作正常。

I had this same problem, after setting up node.js I followed parts of a guide intended for unix and ended up moving my current working directory to a new folder, but I forgot to copy the .npmrc file from the old location to the new one. I also changed the location of my prefix away from %AppData%, which I found by using npm config ls -l to compare my current settings to the default. The two clues here were that I had a line at the start called userconfig pointing to my .npmrc file, which was in a different location, and that my prefix was overridden from the default value. Changing this back to the default fixed the problem.

我有同样的问题，在设置node.js后，我遵循了针对unix的指南部分，最后将我当前的工作目录移动到新文件夹，但是我忘了将.npmrc文件从旧位置复制到新位置一。我还改变了我的前缀的位置，远离％AppData％，我通过使用npm config ls -l将我的当前设置与默认值进行比较。这里的两个线索是我在开始时有一行名为userconfig指向我的.npmrc文件，该文件位于不同的位置，并且我的前缀被默认值覆盖。将此更改回默认值可修复问题。

Try resetting these to the defaults and check what your config settings are. I'm not sure if reinstalling node.js would help anything if it was still referencing your old settings.

尝试将这些重置为默认值并检查您的配置设置。我不确定重新安装node.js是否会有所帮助，如果它仍然引用您的旧设置。

Someone said it was due to npm bug https://github.com/npm/npm/issues/9696

Adding "--force" to install allegedly works around the problem.

I tried following solutions, I don't know which one worked for me.

我尝试了以下解决方案，我不知道哪一个适合我。

• Ran reactive-native init in command prompt as Administrator (on Windows OS), hoping works well with sudo reactive-native init on Mac OS
• 在管理员命令提示符下（在Windows操作系统上）使用active-native init，希望在Mac OS上与sudo reactive-native init配合使用
• Ran npm cache clean command in Command prompt.
• 在命令提示符下运行npm cache clean命令。
• Disable your antivirus for time being.
• 暂时禁用您的防病毒软件。

This is a long standing issue with npm that they seem to have no interest in fixing. Various things others are mentioning will work sometimes (e.g. closing running programs, downgrading the version, etc...). It's been generally limited to Windows installations, though I've even had it happen a bit in Linux lately as well.

对于npm来说这是一个长期存在的问题，他们似乎没有兴趣修复。其他人提到的各种事情有时会起作用（例如关闭正在运行的程序，降级版本等等）。它通常仅限于Windows安装，尽管我最近也在Linux中发生过一些问题。

#9

Upgrade npm to 5.4.2 it will fix this problem.

将npm升级到5.4.2它将解决此问题。

Command to install : npm i -g npm@5.4.2 or npm i -g npm

要安装的命令：npm i -g npm@5.4.2或npm i -g npm

if still doesn't work try clearing cache using npm cache clean

如果仍然不起作用尝试使用npm cache clean清除缓存

you can use force like this npm cache clean --force

你可以使用像这样的强制缓存清理--force

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.

看起来这个错误可能表现不止一个原因，因此可能不会有一个适合每个人的单一修复。

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。根据其中一个相关的npm问题线程的积累智慧，到目前为止已收到近180条评论，其根本问题在于

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。你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，对于某些人来说，关闭IDE或禁用病毒扫描程序有时可以正常工作，但如果并发问题背后的话，并没有真正解决问题。

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

一个补丁已经在npm 5.6.0中登陆了。根据最初的报道，似乎可以做到这一点。因此，如果您的npm --version较低，请更新到5.6.0（或者当您阅读本文时的当前版本）：

npm uninstall -g npm
npm install -g npm@5.6.0

as suggested here.

如此处所示。

If that doesn't help, then perhaps a file lock is the 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，那么文件锁可能是真正的原因。正如@Oly上面所述，关闭IDE，暂时禁用病毒扫描程序，或类似的操作确实是要走的路。

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

对我来说，@ Oly的解决方案有效，我只会为Angular人员添加一些已经锁定文件的服务-o。是的 - 当ng服务正在为项目运行时，不要运行npm install。
