Prerequisite

Before you begin, check whether the Node.js environment exists, and then check whether pnpm is installed.

1. You can use the which command in the terminal to check if pnpm is already installed. This can eliminate the step of installing pnpm:

• Check if Node.js environment exists:

  node -v

• Check if pnpm is installed:

  which pnpm

  If pnpm is already installed, the path information of pnpm will be output. Otherwise, nothing will be output.

  If pnpm is not installed, you can use the following command to install it:

  npm install -g pnpm

  After installation, use the which pnpm command again to check if pnpm has been successfully installed.
