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

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.

E:\Worksapce\web>npm install
npm WARN package.json [email protected] No repository field.

When I tried `npm install -g grunt-cli`, I think it is successful.

E:\Worksapce\web>npm install -g grunt-cli

But when I run grunt, I get an error message like this:

E:\Worksapce\web>
E:\Worksapce\web>grunt
'grunt' is not recognized as an internal or external command,
operable program or batch file.

My package.json is this.

{
"author": "Company",
"name": "registers",
"version": "4.0.0",
"homepage": "http://abcd.se",
"dependencies": {},
"devDependencies": {
"grunt": "~0.4.4",

"grunt-contrib-watch": "~0.6.1",

"grunt-contrib-uglify": "~0.4.0",

}
}

Another user is succesfully able to execute grunt with out any issues. This only stands for some of the users.

Can some one tell me what has gone wrong.

Incase that there some developer that used Windows XP, that have similar problem you'll need to change **Path** entry.

**From**:
C:\Users\change_username\AppData\Roaming\npm\grunt

**To**:
C:\Documents and Settings\change_username\Application Data\npm

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`

Grunt is no longer installed globally. See the [Getting Started][1] page for more information.

The command below should help you fix this;

npm install -g grunt-cli

`Grunt-CLI` is installed inside %AppData%\npm, so the best directory to add to your `%PATH%` is:

%AppData%\npm

Your logs indicate that the `grunt` command was created in your global directory. The errors also indicate that `C:\Users\mc862634\AppData\Roaming\npm\` is not in your path.

You'll want to check your `PATH` and make sure that the `\AppData\Roaming\npm` location is added if it is missing.

The easiest way to check is to open a command prompt and type `PATH`.

)

npm install grunt -g (or) npm install -g grunt-cli
Please check your computer environmental variable path, it should contain the path of AppData. EX: E:\$APPDATA\npm\;
