What should be taken into consideration when installing npm on Linux?

When installing npm on a Linux system, it is important to take note of the following:

  1. Make sure Node.js is installed: npm is the package management tool for Node.js, so Node.js must be installed before npm.
  2. Use the appropriate installation method: On a Linux system, npm can be installed using package managers like apt, yum, dnf, or by using the official installation script provided by Node.js.
  3. Ensure stable network connection: Installing npm requires downloading installation files from the official npm mirror source, so it is important to ensure a stable network connection.
  4. To improve download speed, consider setting the mirror source of npm to a domestic one if the download speed is slow.
  5. Update npm: After installation, it is recommended to update npm to the latest version by using the command npm update npm -g.
  6. Set npm global installation directory: When installing global modules with npm, the default installation path may require sudo permissions. You can avoid using sudo by configuring npm’s global installation directory.
