Mallet installation - Command Prompt error, environmental variable
To install Mallet and set up the environmental variable in the Command Prompt on Windows, follow these steps:
Download Mallet: Go to the Mallet website (http://mallet.cs.umass.edu/download.php) and download the latest version of Mallet for Windows.
Extract Mallet: Extract the downloaded Mallet archive to a directory on your computer. For example, you can extract it to
C:\mallet
.Set up the environmental variable: Open the Command Prompt and execute the following command to set the
MALLET_HOME
environmental variable to the Mallet directory:shellsetx MALLET_HOME "C:\mallet"
This command sets the
MALLET_HOME
variable temporarily for the current session. To set it permanently, you can use the following command instead:shellsetx /M MALLET_HOME "C:\mallet"
Add Mallet to the PATH: To make the Mallet command available from any directory, add the Mallet bin directory to the system's PATH environmental variable. Execute the following command:
shellsetx PATH "%PATH%;%MALLET_HOME%\bin"
This command appends the Mallet bin directory to the existing PATH variable.
Close and reopen the Command Prompt: After making these changes, close the Command Prompt and open a new instance. This ensures that the updated PATH and MALLET_HOME variables take effect.
Test the Mallet installation: To verify that Mallet is installed correctly, type
mallet
in the Command Prompt and press Enter. It should display the Mallet command-line interface and available options.
By following these steps, you should be able to install Mallet and set up the environmental variable in the Command Prompt on Windows.
