The environment variable of

node is matched with

the same problem. Has the landlord solved it? After

nvm instll, you need
nvm use x.x.x
your nvm ls, obviously there is no use 

nvm list available
nvm install 
nvm use install

one more command needs to be executed: 

nvm install node

has the same problem been solved by the landlord?
