node.js - 如何在 Windows 上修复 'npm does not support Node.js v11.14.0 error'？

Question

我正在配置我的 react-native 环境。我正在尝试按照 Facebook 的 Github 文档 here 中的描述运行 react-native 命令行

当我输入 C:\WINDOWS\system32>node -v v11.14. 时，我已经安装了最新版本的 node.js。

下载的 npm 包含在最新版本的 node.js 中。但是它只有 5.5.1。当我输入 C:\WINDOWS\system32>npm -v 结果是 5.5.1

• 我试过卸载并重新安装
• 我已经尝试下载 node.js 的 LTS 版本
• 我已经尝试升级 node.js 和 npm
• 这适用于 Windows 10
• 这是从管理命令提示符和管理电源 shell 运行的

这是代码

C:\WINDOWS\system32>npm install -g react-native-cli
npm WARN npm npm does not support Node.js v10.15.3
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/
npm ERR! Cannot read property 'startsWith' of null

当我尝试使用 npm cache clean -f 清理缓存时，结果是这样

C:\WINDOWS\system32>npm cache clean -f

npm WARN using --force I sure hope you know what you are doing.

我希望打开 npm 命令行界面。我在尝试调用接口(interface)时收到错误消息。

安装当前的 NodeJS LTS 后，我仍然得到 npm 不支持 Node.js {版本}。

我删除了 C:\Users\{user}\AppData\Roaming\npm\ 中的所有文件并且它有效。
