Switch Version
Can already see from the above list of installation, we installed a new version, a stable version. Namely: v12.11.1 and v10.16.3, how do we switch to a different version of it?
1. Switch to v12.11.1, the command:
display:
Now using node v12.11.1 (npm v6.11.3)
2. Switch to v10.16.3, the command:
display:
Now using node v10.16.3 (npm v6.9.0)
Here, we will use the basic nvm, and to use whatever version you can switch freely. But if you want to play a little more cool, we should learn some tips below.
Using aliases
You must also think of each input v10.16.3 good trouble. And a long time, not necessarily remember back to live 16.3 or 18.3 version.
1, set the alias LTS version, the command:
display
10 -> v10.16.3
2, the latest version of the set alias command:
display
12 -> v12.11.1
