Node (v10.15.0) npm cannot be used?

I originally downloaded node via nvm (v7.8.0), when node had integrated npm (figure 1), and I installed another npm globally through this npm (figure 3). Recently I downloaded node via nvm (v10.15.0), but I don"t see npm in the folder (figure 2). Is the new version of node not integrated with npm? Every time I cut to the version of v10.15.0, the global npm cannot be used. Why?

nvm has a sandbox mechanism, and different versions of node should be isolated. I didn't quite understand the meaning of your question.


1. The new version still has npm, as shown in the following figure. This is installed through the installation package. Guess that nvm does not integrate npm;

in version 10.15.

2. After installing 10.15, the global npm cannot be used. Is it a prompt that the path cannot be found? Or is it something wrong?
