In this article, we will discuss the possible causes of this error and how to troubleshoot and fix it.

Possible causes of 'bash: gulp: command not found'

How to troubleshoot and fix 'bash: gulp: command not found'

1. Install Gulp: To install Gulp, run the following command in your terminal:

3. Set up the path environment variable: To add the path to Gulp to your system's path environment variable, run the following command in your terminal:

   export PATH=$PATH:/usr/local/lib/node_modules/gulp/bin
   

   Replace /usr/local/lib/node_modules/gulp/bin with the path to your Gulp installation folder.

4. Verify the installation: After installing Gulp and setting up the path environment variable, you can verify the installation by running the following command:

   gulp --version
   

   If Gulp is installed correctly, you should see the version number of Gulp printed in your terminal.
