I see multiple people asking the same questions about trying to run create-react-app, which then claims an older version of Node is running, even though I uninstalled it via nvm multiple times. Here's one example of my attempts to choose a later version of node I have already installed:
Mac:react me$ nvm install v16.13.2
v16.13.2 is already installed.
Now using node v16.13.2 (npm v8.1.2)
Mac:react me$ npx create-react-app@latest my-app
You are running Node 12.14.1.
Create React App requires Node 14 or higher.
Please update your version of Node.
Mac:react me$ npm uninstall -g v12.14.1

Now using node v16.13.2 (npm v8.1.2)
Mac:react me$ npx create-react-app@latest my-app
You are running Node 12.14.1.

I'm running High Sierra, so can't update to the latest/greatest verison of node, but as I understand it, I shouldn't have to. How do I fix this so I can actually run create-react-app on my system? Many thanks in advance for your help.
The only solution that worked for me was to both remove node and nvm via CLI and manually. nvm isn't needed on my system anymore, as previous versions of node were for legacy projects I'm no longer working on.
The CLI solution (largely using Homebrew) is discussed many places on SO, including here, and manually also many places online, notably here.
