Why doesn\'t the \'node\' command work after installing Node.js on Ubuntu 12.04?

Nodejs vs Node on Ubuntu 12.04

When installing Node.js on Ubuntu 12.04, you may encounter the issue where the node command doesn't exist in the terminal. This is due to a naming conflict with the Amateur Packet Radio Node Program, which has resulted in the Node.js binary being renamed to nodejs.

To resolve this issue, you need to create a symbolic link from /usr/bin/node to /usr/bin/nodejs. This can be done using the following command:

sudo ln -s `which nodejs` /usr/bin/node

Alternatively, if you use a non-standard shell, you can hardcode the path found with which nodejs:

sudo ln -s /usr/bin/nodejs /usr/bin/node

This will create the missing node symlink and allow you to use the Node.js commands with the node alias.

Additionally, if you use the zsh shell instead of bash, the node command should work without modification. However, if the issue persists, you can try the following additional solutions:

• Install Node.js using alternatives:

  sudo update-alternatives --install /usr/bin/node node /usr/bin/nodejs 10

  Copy after login

• Purge and reinstall Node.js:

  sudo apt-get --purge remove node
  sudo apt-get --purge remove nodejs
  sudo apt-get install nodejs

  Copy after login
