The error message you are seeing ‘postcss’ is not recognized as an internal or external command, operable program or batch file usually occurs when the ‘postcss’ command is not recognized by your command-line interface (CLI).
This error typically occurs when ‘postcss’ is not installed globally or it is not in the system’s PATH. To resolve this issue, you need to install ‘postcss’ globally or specify the correct path to the ‘postcss’ executable.
Example 1: Installing postcss globally
To install ‘postcss’ globally, you can use the following command:
npm install -g postcss
After the installation completes, you should be able to use the ‘postcss’ command in your command-line interface without encountering the error.
Example 2: Specifying the correct path to postcss executable
If you have ‘postcss’ installed locally within your project’s dependencies, you can specify the correct path to the ‘postcss’ executable in the command.
./node_modules/.bin/postcss [options]
By prefixing the ‘postcss’ command with ‘./node_modules/.bin/’, you are providing the explicit path to the ‘postcss’ executable within your project’s node_modules directory.
Make sure you are running the command within the appropriate directory where your project is located.
