pnpm setup

此命令用於 pnpm 的單獨安裝指令稿。 For instance, in https://get.pnpm.io/install.sh.

安裝指令稿會執行以下操作：

• 為 pnpm CLI 建立主目錄
• adds the pnpm home directory to the PATH by updating the shell configuration file
• when pnpm runs as a standalone executable, installs it as a global package and writes the pn, pnpx, and pnx scripts to $PNPM_HOME/bin

If pnpm setup cannot tell which shell configuration file to update, for example in a container where SHELL is not set, it still installs pnpm. It then prints the PNPM_HOME and PATH lines to add to your shell configuration yourself.

On Windows, if the registry environment values cannot be read or written, pnpm setup still installs pnpm. It prints commands to set PNPM_HOME and PATH in the current PowerShell session. Add these commands to your PowerShell profile to use pnpm in future sessions without registry access.

Since v11.18.0, when running on GitHub Actions, pnpm setup also appends PNPM_HOME and the global bin directory to the GitHub Actions environment files (GITHUB_ENV and GITHUB_PATH), so later steps in the same job can run pnpm add --global and other global commands.
