How can I help pnpm find its global directory?

PNPM is an efficient package manager that saves disk space and accelerates dependency installation by utilizing hard links and symbolic links. By default, PNPM sets the global directory within a subdirectory of the user's home directory. However, users may need to change this location for reasons such as disk space constraints or multi-user sharing requirements.

To modify PNPM's global directory, set the environment variable PNPM_HOME. Here are the specific steps:

1. Find the Current Global Directory: Before making changes, run the following command to locate the current global directory path:

   bash
   pnpm config get global-dir

2. Set the PNPM_HOME Environment Variable: Configure PNPM_HOME in your shell configuration file (e.g., .bashrc, .zshrc, or other relevant files) to point to the new directory. For example:

   bash
   export PNPM_HOME="/new/path/to/global"

3. Apply the Changes: After updating the configuration file, reload it or restart your terminal to apply the changes. Reload the configuration file using:

   bash
   source ~/.bashrc  # or the corresponding configuration file

4. Verify the Change: After setting the environment variable, running pnpm config get global-dir again will display the new global directory path.

This successfully modifies PNPM's global directory location, enabling better disk resource management and customizable configuration based on specific needs.
