Set Default Node Version
Installing Node Version Manager (NVM)
Before we can start setting the default Node.js version, we first need to install NVM. NVM is a version manager for Node.js that allows you to easily switch between different Node.js versions. The installation process varies depending on the operating system you are using.
For Unix-based systems (like Linux or macOS), you can install NVM by running the following command in your terminal:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
For Windows, you can download the installer from the official NVM repository on GitHub and follow the on-screen instructions.
Once NVM is installed, you can verify the installation by running the following command:
Choosing the Desired Version of Node.js
Once you have NVM installed, you can choose the desired version of Node.js to set as the default. NVM allows you to install and use multiple versions of Node.js side by side, so you have the flexibility to work with different versions based on your project’s requirements.
To see a list of all available Node.js versions, you can use the following command:
This will list all the available Node.js versions that you can install. To install a specific version, you can use the following command:
For example, if you want to install Node.js version 14.17.3, you would run:
nvm install 14.17.3
Setting the Default Node.js Version Globally
To set a default Node.js version globally, you can use the following command:
nvm alias default
For example, if you want to set Node.js version 14.17.3 as the default, you would run:
nvm alias default 14.17.3
Verifying the Installed Node.js Versions
To verify the Node.js versions installed on your system, you can use the following command:
This will list all the installed Node.js versions and indicate which version is currently set as the default.
Using NVM to Switch Between Node.js Versions
One of the key features of NVM is the ability to easily switch between different Node.js versions. To switch to a specific Node.js version, you can use the following command:
For example, if you want to switch to Node.js version 12.22.6, you would run:
nvm use 12.22.6
Setting the Default Node.js Version Locally per Project
In addition to setting the default Node.js version globally, NVM also allows you to set the default version locally per project. This is useful when you have multiple projects that require different Node.js versions.
To set the default Node.js version locally, you can create a `.nvmrc` file in the root directory of your project. Inside the file, you specify the desired Node.js version. For example, if you want to set Node.js version 14.17.3 as the default for a specific project, you would create a `.nvmrc` file with the following content:
After creating the `.nvmrc` file, you can use the following command to automatically switch to the specified version when you enter the project directory:
Using NVM Aliases to Simplify Version Switching
NVM aliases allow you to create custom names for specific Node.js versions, making version switching even easier. To create an alias for a specific version, you can use the following command:
For example, if you want to create an alias named `default` for Node.js version 14.17.3, you would run:
nvm alias default 14.17.3
After creating an alias, you can switch to the aliased version by simply using the alias name:
Automatically Switching Node.js Version when Changing Directories
NVM provides a handy feature called directory-based versioning that allows you to automatically switch Node.js versions based on the project directory you are in. To enable this feature, you can use the following command:
nvm use –auto
When you navigate to a directory containing a `.nvmrc` file, NVM will automatically switch to the Node.js version specified in that file.
