I'm trying to set up npm truffle in the terminal in visual studio, but I got failure message saying npm WARN deprecated.
The command I use is npm install truffle -g
What should I do next? What updates do I need to do?
No need to worry. This is not a failure message but just some warnings. If you get errors, something went wrong. Truffle will work just fine. You can verify that the installation was successful with
truffle --version
