pnpm failure to find the Global Bin Directory when using the -g flag

Some students have issues with installing @upleveled/preflight after they have successfully run the pnpm installation using corepack

The pnpm installation was completed with the code below

corepack enable
corepack prepare pnpm@latest --activate
pnpm setup
source ~/`[[ $SHELL == *"zsh" ]] && echo '.zshrc' || echo '.bash_profile'`

But running pnpm add --global @upleveled/preflight to install Preflight caused the error below, and running pnpm setup multiple times or repeating the while pnpm setup again could not solve the issue

ERR_PNPM_NO_GLOBAL_BIN_DIR  Unable to find the
global bin directory

Run "pnpm setup" to create it automatically,
or set the global-bin-dir setting, or the
PNPM_HOME env variable. The global bin
directory should be in the PATH.E env variable. The global bin directory should be in the PATH.

A similar issue is reported on GitHub => https://github.com/pnpm/pnpm/issues/5883

Started a new issue in pnpm GitHub for this problem => https://github.com/pnpm/pnpm/issues/8997

Note

There was the correct pnpm setting in the .zshrc file, and preflight was also located in /Users/[email protected]/Library/pnpm/preflight which seems correct

# pnpm
export PNPM_HOME="/Users/[email protected]/Library/pnpm"
case ":$PATH:" in
  *":$PNPM_HOME:"*) ;;
  *) export PATH="$PNPM_HOME:$PATH" ;;
esac
# pnpm end

The following steps solved it

1. run this pnpm config set global-bin-dir /Users/[email protected]/Library/pnpm
2. rerun Preflight installation: pnpm add --global @upleveled/preflight
