PM2 NODEJS error how to fix?

Question

Node.js

Started learning NODEJS, installed nodejs package in Ubuntu. I launched a test file hello.js in the terminal, launching an http server with the output Hello Word (node ​​/usr/share/nginx/node/hello.js) - everything works.
Now, as I understand it, in order to start the server without blocking the terminal, you need PM2. Installed.
However, any pm2 commands simply or pm2 start /usr/share/nginx/node/hello.js
gives an error:

/usr/local/lib/node_modules/pm2/node_modules/debug/src/node.js:132
        let val = process.env[key];
        ^^^

How to fix and what kind of error is this?

Answer 1

You have an old node installed, the eighth one is in the default repository.
Here's how to install a new one

Answer 2

Also, to unhook the node from the terminal, an ampersand at the end of the command is enough, node ххх.js &
pm2 is "from a cannon to sparrows". But restarts, turns logs, yes.
