nvm | personal notes

Installation on macOS

Check environment first

$ node -v
v12.14.0
$ brew ls node
/usr/local/Cellar/node/13.5.0/bin/node
/usr/local/Cellar/node/13.5.0/etc/bash_completion.d/npm

From this issue https://github.com/nvm-sh/nvm/issues/1918, seems that you have to uninstall the node installed by homebrew.

Follow the steps in uninstall steps for homebrew to uninstall/remove all the version of node installed by Homebrew.

Follow the installation steps on https://github.com/nvm-sh/nvm

$ brew ls nvm
Error: No such keg: /usr/local/Cellar/nvm

This means nvm is still not installed yet.

$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash

$ nvm list
zsh: command not found: nvm

Add below lines to ~/.zshrc

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm

Open a new terminal window.

Verify the nvm installation.

$ command -v nvm
nvm

If there is node already installed by Homebrew, you will see system.

$ nvm list

->       system
iojs -> N/A (default)
node -> stable (-> N/A) (default)
unstable -> N/A (default)
nvm_list_aliases:36: no matches found: /Users/devin.chenyang/.nvm/alias/lts/*

If all the node installed are uninstalled, you will see:

$ nvm list
            N/A
iojs -> N/A (default)
node -> stable (-> N/A) (default)
unstable -> N/A (default)
nvm_list_aliases:36: no matches found: /Users/devin.chenyang/.nvm/alias/lts/*

See which node version can be installed by nvm, run nvm ls-remote. This will print a lot info…

First, I want to install the latest LTS version.

$ nvm install 12

Then check the installation

$ nvm ls
->     v12.16.1
default -> 12 (-> v12.16.1)
node -> stable (-> v12.16.1) (default)
stable -> 12.16 (-> v12.16.1) (default)
iojs -> N/A (default)
unstable -> N/A (default)
lts/* -> lts/erbium (-> v12.16.1)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.19.0 (-> N/A)
lts/erbium -> v12.16.1

Then I’d like to install version 8 for some old projects.

$ nvm install 8

Checked the installation.

$ nvm ls
->      v8.17.0
       v12.16.1
default -> 12 (-> v12.16.1)
node -> stable (-> v12.16.1) (default)
stable -> 12.16 (-> v12.16.1) (default)
iojs -> N/A (default)
unstable -> N/A (default)
lts/* -> lts/erbium (-> v12.16.1)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0
lts/dubnium -> v10.19.0 (-> N/A)
lts/erbium -> v12.16.1

I switch to the lastest version to develop the new projects.

$ nvm use 12
Now using node v12.16.1 (npm v6.13.4)

Installed yarn again since I remove it when uninstalling node.

$ brew install yarn

Seems that brew automatically install node 13 for me. So I will check the node version first.

$ node -v
v12.16.1

So it’s still the version installed by nvm.
