To install the latest pnpm and the node LTS run the following in your terminal:
curl -fsSL https://get.pnpm.io/install.sh | sh -
bash # or restart the terminal to load new $PATH
pnpm env use --global latest # install node (latest)
pnpm env use --global lts # install node (and switch to Long Term Support)
pnpm --version # should output something like 9.12.0
node --version # should output something like v22.11.0
which pnpm # should output something like ~/.local/share/pnpm/pnpm
which node # should output something like ~/.local/share/pnpm/node
If which outputs something other than ~/.local/share/pnpm/... it’s probably because
you already have node or pnpm installed and your $PATH is finding those first.
