Install pnpm on macOS - pnpm setup bug - $PNPM_HOME set incorrectly - results in "no such file or directory"

[aburd]

Issue

macOS system (Sequoia 15.7.2)

When trying to install pnpm using these methods:

https://pnpm.io/installation#on-posix-systems
or
https://pnpm.io/installation#using-npm

I got messages like below:

 ERROR  ENOENT: no such file or directory, mkdir '/home/<user>/.local/share/pnpm/.tools/pnpm/10.24.0_tmp_85172'

Since on my mac system /home/<user> is not my home directory, it cannot find this directory

Work Around

Do basic setup

# install the binary
npm install -g pnpm@latest-10
# run the pnpm setup
pnpm setup

This will write something like this to your .bash_profile or whatever shell config you're using

# pnpm
export PNPM_HOME="/home/<user>/.local/share/pnpm"
case ":$PATH:" in
  *":$PNPM_HOME:"*) ;;
  *) export PATH="$PNPM_HOME:$PATH" ;;
esac
# pnpm end

Then edit the $PNPM_HOME correctly using whatever $HOME is set to. In my case it was something like /Users/<user>

# pnpm
export PNPM_HOME="/Users/<user>/.local/share/pnpm"
case ":$PATH:" in
  *":$PNPM_HOME:"*) ;;
  *) export PATH="$PNPM_HOME:$PATH" ;;
esac
# pnpm end

After opening a new shell, you should be able to use pnpm
