sudo: npm: command not found

If you get the error message "sudo: npm: command not found", it means that the npm command is not installed on your system or it is not in your PATH environment variable. To fix this error, you can try the following steps:

  1. Ensure you have installed Node.js on your system, as npm is included with Node.js. You can check if Node.js is installed by running the command node -v in your terminal. If Node.js is not installed, you can download and install it from the official website: https://nodejs.org/

  2. If you have installed Node.js but are still getting the "sudo: npm: command not found" error, it is possible that the npm command is not in your PATH environment variable. You can add it to your PATH by running the following command in your terminal:

export PATH="$PATH:/path/to/node_modules/.bin"
  1. If you still have issues, try running the npm command with the full path to the npm executable. For example:

/path/to/node_modules/.bin/npm install <package>

Install Node.js

  1. Download the Node.js installer from the official website: https://nodejs.org/

  2. Run the downloaded installer and follow the on-screen instructions to install Node.js on your system.

  3. Once the installation is complete, you can verify that Node.js is installed by running the following command in your terminal:

This will print the version number of Node.js that you have installed.

What is Node.js

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside a web browser. It is commonly used for building server-side applications and creating command-line tools and utilities. Node.js is built on Chrome's V8 JavaScript engine, providing a rich set of built-in modules and libraries for working with the file system, networking, and other common tasks. It also has a large and active community of users and developers who contribute to the project and create a wide range of third-party modules and tools. Node.js is often used for building web servers and APIs and is well-suited for real-time applications requiring high performance and concurrency. It is also popular among front-end developers who use it for building and testing their web applications.
