With the development of front-end engineering and automation, Node.js and Gulp have become indispensable tools for front-end development. If you are a front-end developer and don’t have Node.js and Gulp installed, this article will teach you how to install Node.js and Gulp environment variables.

Install Node.js

Node.js is a JavaScript running environment based on the V8 engine, which allows JavaScript code to run on the server side. Node.js uses NPM (Node Package Manager) to manage and install third-party dependent packages, making it easier for developers to manage project dependencies.

Install Gulp

Gulp is an automated build tool based on Node.js. It can help developers automatically complete operations such as building, compressing, merging, and copying, reducing repetitive tasks. work, improving development efficiency.

The following are the steps to install Gulp:

1. Use npm to install Gulp.

Enter the following command on the command line:

npm install -g gulp

2. Create a project and install gulp.

Enter the following commands on the command line:

The following are the steps to configure environment variables under Windows systems:

1. Right-click "This PC" on the desktop and select "Properties".
2. Click "Advanced System Settings" to open the "System Properties" window.
3. Click the "Environment Variables" button.
4. In the "System Variables" area, find the variable named Path and click the "Edit" button.
5. In the pop-up editing window, add the installation paths of Node.js and Gulp at the end of the variable value, and separate the paths with semicolons.
6. Click the "OK" button to save changes.
7. Open the command line and enter the node -v and gulp -v commands. If the version numbers of Node.js and Gulp are output, it means that the environment variables are configured successfully.

Conclusion

The above are the detailed steps for installing Node.js and Gulp environment variables. By installing and configuring these tools, front-end developers can help complete project development and maintenance more efficiently. If you encounter problems with installation and configuration, you can refer to the official documentation or ask the development community for help.
