00:11:40 Switching between different NodeJS Versions using n
00:14:59 Uninstall NodeJS using n
00:15:34 Uninstall n
1. Type the following command to install Node.js and NPM:
brew install node
Homebrew downloads and installs the dependencies for the latest version of Nodejs and NOT the LTS Version.
To Install the LTS version or any other version type:
brew install node@18
If another version of Node is already installed, you should uninstall it first to avoid conflicts.
Also note that LTS versions of node (e.g. node@18) are keg-only and must either be linked with --force (brew link --force node@18) or you need to add the binary to your path by running:
$nano ~/.zshrc
export PATH="/usr/local/opt/node@18/bin:$PATH"
2. When the installation finishes, confirm that you successfully installed Node.js by checking its version:
node -v
3. Next, check the installed version of NPM by typing:
npm -v
Step 3. Update Node.js and NPM on Mac
brew upgrade node
1. Uninstall both Node.js and NPM with the brew uninstall command:
brew uninstall node
2. Remove all the unused dependencies with:
brew autoremove
This command removes the packages that brew uninstall did not remove.
npm install -g n
The n command downloads and installs to /usr/local by default.
On macOS with Homebrew you can install the n formula.
brew install n
Installing Node.js Versions
Simply execute n version to download and install a version of Node.js. If it has already been downloaded, n will install from its cache.
n 10.16.0
n lts
Execute n on its own to view your downloaded versions, and install the selected version.
$ n
node/4.9.1
ο node/8.11.3
node/10.15.0
Use up/down arrow keys to select a version, return key to install, d to delete, q to quit
If the active node version does not change after install, try opening a new shell in case seeing a stale version.
Specifying Node.js Versions
Numeric version numbers can be complete or incomplete, with an optional leading v.
4.9.1
8: 8.x.y versions
v6.1: 6.1.x versions
There are labels for two especially useful versions:
• lts: newest Long Term Support official release
• latest, current: newest official release
There is support for the named release streams:
argon, boron, carbon: codenames for LTS release streams
Miscellaneous
Command line help can be obtained from n --help.
List matching remote versions available for download:
n ls-remote lts
n ls-remote latest
n lsr 10
n --all lsr
List downloaded versions in cache:
n ls
Display diagnostics to help resolve problems:
n doctor
