I just installed node v9.11.1when I try to use npm I keep getting the following error:
v9.11.1当我尝试使用 npm 时，我刚刚安装了节点，但不断收到以下错误：
npm WARN npm npm does not support Node.js v9.11.1
npm WARN npm You should probably upgrade to a newer version of node as we
npm WARN npm can't make any promises that npm will work with this version.
npm WARN npm Supported releases of Node.js are the latest release of 4, 6, 7, 8.
npm WARN npm You can find the latest version at https://nodejs.org/
I tried to do npm i -g npmbut it couldn't update itself, it just kept throwing the same error above.
我尝试这样做，npm i -g npm但它无法自行更新，它只是不断抛出上述相同的错误。
When I run npm -vit says 5.5.1it seems the latest version is currently 5.8.0.
当我运行时，npm -v它说5.5.1目前似乎最新版本是5.8.0.
I tried deleting the folder and running the repair function on the node.js installer, but it didn't replace the module.
我尝试删除文件夹并在 node.js 安装程序上运行修复功能，但它没有替换模块。

npm list -g
For Windows this will most likely be:
对于 Windows，这很可能是：
%AppData%\npm\node_modules
%AppData%\npm\node_modules
You can paste that into a folder's address bar and it will take you there.
您可以将其粘贴到文件夹的地址栏中，它会带您到那里。
Once there delete the folder named npm.
一旦有删除名为npm.
Download the Latest Release of NPM
下载最新版本的 NPM
https://github.com/npm/cli/releases/latest
https://github.com/npm/cli/releases/latest
Grab the zip and unzip it to your node_modulesfolder that you just deleted the npm folder from.
获取 zip 并将其解压缩到您node_modules刚刚从中删除 npm 文件夹的文件夹中。
Rename the folder you extracted from the zip to npm
将您从 zip 中提取的文件夹重命名为 npm
If you get any warnings about the file path or name being too long skip the warnings.
如果您收到有关文件路径或名称太长的任何警告，请跳过这些警告。
Update for Good Luck
祝你好运更新
Now you should be able to run npm i -g npmto update/reinstall npm without any warnings.
现在，您应该能够在npm i -g npm没有任何警告的情况下运行以更新/重新安装 npm。
I find this step especially important if you had errors in Windows about the path or file name being too long.
如果您在 Windows 中遇到关于路径或文件名太长的错误，我发现这一步尤其重要。
You may get the following errors. If you do go and delete or move the files it has listed and you should be able to run npm i -g npmsuccessfully.
您可能会收到以下错误。如果你确实去删除或移动它列出的文件，你应该能够npm i -g npm成功运行。

For me even deleting npm folder or reinstalling Node didn't help. After updating Nodejs and npm to latest version (Node 10.19, npm 6.14.3) of my CentOS 6, I've got constant libs error with npm while Node was fine.
对我来说，即使删除 npm 文件夹或重新安装 Node 也无济于事。将 Nodejs 和 npm 更新到我的 CentOS 6 的最新版本（Node 10.19，npm 6.14.3）后，当 Node 运行良好时，我的 npm 不断出现 libs 错误。
What's worked - nNode version manager. With this command I could reverse my npm version: n -p 6.13link
什么有效 -n节点版本管理器。使用此命令，我可以反转我的 npm 版本：n -p 6.13链接
