I'm having a problem with npm on my Ubuntu 20.04 machine. I try to check its version (I've just installed it with sudo apt install npm, I have NodeJS version 10.19.0) and I don't get any output, just immediately next line in terminal:

Same thing happens when I try to install something, for instance json-server with npm install json-server -g. I don't get any output at all, nothing happens.

It may be that json-server is already installed, because I don't get any error when I'm trying to use it. However, when I try to write json-server --watch someFile.json, still nothing happens, there is no hosting of this json file.

What may be the reason of this problem?

Installing with nvm solved the problem.
