How to upgrade Node version on Mac.

Conditions:

After I inputted vue command (vue-cli), I got the error message:

You are using Node v8.0.0, but this version of vue-cli requires Node >=8.9.
Please upgrade your Node version.

I forgot how to install Node.js on my Mac. I use Homebrew to upgrade Node.js but it installed at different location (/usr/local/Cellar/node/10.12.0). Current Node.js was installed at /usr/local/bin/node . After installed the new version of Node.js by HomeBrew, I got the same error message again.

Solution:

1. Because I forgot how to install Node.js on my Mac. Based on the article 4 ways to update to the latest Node.js version on a Mac, I tried to find out my way.

(1) Check if I used NVM (Node Version Manager) to install Node.js

nvm
# zsh: command not found: nvm 

(2) Check if I used Homebrew to install Node.js

brew upgrade node
# Error: node not installed

(3) Check if I used N to install Node.js

n
# zsh: command not found: n

(4) Check if I used MacPorts to install Node.js

port
# zsh: command not found: port

Finally, I figured out I download the Node.js installer from official website.

2. Use HomeBrew remove the installed package

brew remove node
# Uninstalling /usr/local/Cellar/node/10.12.0... (3,939 files, 46.6MB)

3. Check the current status before upgrade Node version
(1) Current version of Node

node -v
# v8.0.0

(2) Current installed path of Node

which node
# /usr/local/bin/node 

4. Check the version of Node after installation

node -v
# v8.12.0

5. Now I can input vue command

Usage: vue <command> [options]
Options:
  -V, --version                         output the version number
  -h, --help                            output usage information
