So I'm learning node.js. I am following this tutorial to install it and try some things.

Anyway, npm behaves really weird. It will work fine for a while (I changed its viewer configuration settings, for example), but then it suddenly “disappears”, so the next time I enter

npm ...(anything)

on the command line, my shell tells me that the npm command was not found. Uninstalling and then reinstalling npm using nvm used to work, but I would prefer not to do it every ten minutes, and it’s very strange for me that it suddenly stops working.

I think the last time it stopped working after I edited and then processed the ~ / .zshrc file - just added npm and node tab completion plugins.

Any idea what is going on? I will post the results of a few basic commands, but I am really poor at sysadmin, and I really don't know what to look for here.

nvm -ls

   v0.8.22
current:    v0.10.2
default -> 0.8 (-> v0.8.22)

which node

/usr/bin/node

where npm

npm not found

My root folder has both nvm (is it a duplicate?) And npm directories.

If I go to / usr / bin, node is a file, not a directory. There is also an npm file, but not an nvm file.

As can be seen from all of the above, I really do not know what is happening. I was looking for this, but it seems this problem is not. Any ideas on what's going on or how to find out?
