NVM - Node Version Manager

Node version issues

• To run any Angular project, we need to have a specific version of Node.js installed.

• Installing Node.js requires admin rights, but we can only install and use one version at a time.

About NVM

• NVM is a tool that manages multiple Node versions on your device. It’s useful because different projects may require different Node versions, and using a single version might not yield correct results.

• To switch between different versions smoothly and quickly, we can use Node Version Manager (nvm).

NVM Installation (Without Admin Rights)

Install bash terminal

• If using windows install bash terminal

Clone nvm Repository

• Run the following commands in cmd or bash terminal.

• This command will clone the nvm repository to a ~/.nvm directory on your device.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

# or

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

Create .bashrc file in Home Directory

• Windows Home Directory : C:\Users\<Your_Username>\

• Create a .bashrc file with the following code

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

Reopen the Bash

• Open the bash terminal by using bash keyword in cmd.

• check whether nvm is working by verifying its version.
