'grunt' is not recognized as an internal or external command for some windows users

Question

Grunt is not working for all Windows users. Some users are facing some issues, when I run npm install command; it prints a message as below.

Answer 1

On Windows 8, Grunt needs to have the following added to the PATH:

C:\Users\your_username\AppData\Roaming\npm

On some systems, the number of characters allowable in the PATH is limited, and this can cause the correct path needed by grunt to not be added, even after npm install -g grunt-cli is run. Some settings (for example for certain programs you have installed) can be safely removed from the PATH, as they're generally there as a failsafe and often aren't required. If you have this issue:

• Backup the variables in your PATH (This PC > right-click > Properties > Advanced system settings > Environment Variables > 'Edit' the 'Path' user variables for the current user, and copy the 'Variable value' and save it somewhere)
• Remove some of the values from the PATH, and add in the path C:\Users\your_username\AppData\Roaming\npm

Also, make sure that after installing the Grunt CLI and adding the path, that you close any open command windows and re-open them before trying a Grunt
