为什么 npm 安装在我的设备上不起作用，即使我重新安装也无法查看版本详细信息？

Question

I'm completely new to using Node and am honestly very confused about how this all works. I have installed node and NPM but every time I try to check the version to see if it's installed, it tells me "command not found". I've been at this for almost 2 hours just deleting all the npm/node files and reinstalling but nothing seems to give. Can someone please explain if there is anything I can do to fix this issue?

-bash: npm: command not found

If I go inside the NPM file through the terminal, it shows me this when I try to run npm install or npm start.

> npm start
npm should be run outside of the Node.js REPL, in your normal shell.

Add npm to your path (environment variable on windows not sur on linux) if you are using a portable version, if you are using an installed version of node, it should add npm to your path automatically on windows, not sure on linux, npm start will run the start script from your project package.json file. try going into your npm executable folder (generally in node installation folder), n do a./npm i -g npm
