How to Install Elixir and Phoenix Framework on Ubuntu 21.04 LTS

Node.js

check latest

https://github.com/nvm-sh/nvm/releases
2021/7はv0.38.0が最新なのでv0.38.0をインストールする。

Install nvm

export NVM_DIR="$HOME/.nvm" && (
  git clone https://github.com/nvm-sh/nvm.git "$NVM_DIR"
  cd "$NVM_DIR"
  git checkout `git describe --abbrev=0 --tags --match "v[0-9]*" $(git rev-list --tags --max-count=1)`
) && \. "$NVM_DIR/nvm.sh"

Now add these lines to your ~/.bashrc, ~/.profile, or ~/.zshrc file to have it automatically sourced upon login: (you may have to add to more than one of the above files)

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
