Installing and Managing Multiple Node.js Releases

Before we delve into NVM and the bash nvm not found error, let’s first understand the significance of Node.js releases and why managing them is essential. Node.js releases can vary in functionality and compatibility, and new releases are often released to fix bugs or add new features.

Therefore, it’s crucial to have multiple Node.js releases installed on your computer if you’re planning to run different projects with different versions. NVM allows users to install and switch between different Node.js releases, giving them the flexibility to test their projects with multiple versions.

NVM works by installing multiple versions of Node.js into a separate directory, which is isolated from the system-installed Node.js. With NVM, users can easily switch between different versions of Node.js, making it an essential tool for Node.js developers.

Problem of Bash NVM Not Found Error

Despite its usefulness, NVM can experience some issues, and the most common error is “bash: nvm: command not found.” This error occurs when the system cannot locate the NVM command, making it impossible for users to manage their Node.js releases. Several factors can cause this error, such as installing NVM incorrectly or not installing it at all.

If you see the bash nvm not found error, don’t worry, as there are simple solutions that can help you fix the problem.

Checking Whether NVM Tool is Installed on System or Not

Before resolving the bash nvm not found error, it’s essential to check if NVM is installed on your system. The process of checking NVM installation is simple and requires opening the terminal or Kali Linux shell and entering the following command:

“`

nvm –version

“`

If NVM is installed on the system, this command will display the version number, indicating that NVM is correctly installed. However, if NVM is not installed, the system will display an error message that reads “bash: nvm: command not found.”

Output of NVM Not Being Installed

If the system displays the “bash: nvm: command not found” error message, it’s an indication that NVM is not installed on your system. To install NVM, follow the steps below:

Step 1: Open the terminal or Kali Linux shell and enter the following command:

“`

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

“`

Step 2: The above command will download and run a script that will install NVM on your system.

Step 3: Once the installation is complete, you need to refresh the terminal or Kali Linux shell by running the following command:

“`

source ~/.bashrc

“`

Step 4: Now that NVM is installed on your system, you can check its version by running the following command:

“`

nvm –version

“`

The above command should display the version number, indicating that NVM is correctly installed on your system. If the system displays an error message, it’s best to try reinstalling NVM from scratch.

3) Setting Up NVM Tool on Kali Linux

Installing NVM on Kali Linux is relatively straightforward, but some additional configuration is necessary to ensure that the tool works correctly. In this section, we’ll provide a step-by-step guide on how to set up NVM on Kali Linux, including adding configurations, setting up the path to the NVM directory and using ENV variables, sourcing, and downloading and installing NVM using GitHub Remote Repository.

Adding Configurations and Setting Path to NVM Directory

To set up NVM on Kali Linux, you first need to add some configurations and set up the path to the NVM directory. This step is essential, as it will ensure that your system can locate NVM and load it correctly.

Generating or Opening .bash_profile File

To add configurations and set up the path to the NVM directory, you need to create or open a file called .bash_profile. This file is responsible for storing various user-specific settings, including the path to the NVM directory.

You can generate or open the .bash_profile file using a text editor of your choice.

Creating Path for NVM Directory, Exporting it Using ENV Variable and Sourcing it

After opening the .bash_profile file, you can create a path for the NVM directory and export it using an “ENV” variable.

To do this, add the following commands to the .bash_profile file:

“`

export NVM_DIR=”$HOME/.nvm”

[ -s “$NVM_DIR/nvm.sh” ] && . “$NVM_DIR/nvm.sh”

“`

These commands create a path for the NVM directory in the .bash_profile file and export it using an “ENV” variable.

This will allow your system to load NVM correctly when you run it.

Downloading and Installing NVM Tool Using GitHub Remote Repository

Once you’ve added the configuration and set up the path to the NVM directory, you’re ready to download and install NVM using the GitHub Remote Repository. To do this, run the following command in the terminal or Kali Linux shell:

“`

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

“`

This command will download and run a script that will install NVM on your system.

Applying the Changes Done by Installing NVM

After installing NVM on your system, you need to ensure that the changes made are applied. To do this, you can run the following command:

“`

source ~/.bash_profile

“`

This command will apply the changes made by installing NVM, ensuring that your system can locate and load NVM correctly.
