The “Couldnt launch Python exit code 9009” error message typically indicates that the system is unable to find the Python executable in the system PATH environment variable. Here are the steps you can follow to resolve this issue:
Step 1: Check if Python is installed
The first step is to make sure that Python is installed on your system. To check this, open the command prompt and type “python” and press Enter.
If Python is installed, it will start the Python interpreter and show the version number. If it is not installed, then you need to download and install it from the official website (https://www.python.org/downloads/).
Step 2: Check the System PATH environment variable
The next step is to check if the Python installation directory is added to the system PATH environment variable.
To check this, open the command prompt and type the following command:
This will display a list of directories that are included in the system PATH environment variable. Check if the Python installation directory is listed in the output. If it is not listed, you need to add it manually.
Step 3: Add Python directory to the system PATH environment variable
To add the Python directory to the system PATH environment variable, follow these steps:
- Open the Control Panel and click on “System”.
- Click on “Advanced system settings” on the left-hand side.
- Click on the “Environment Variables” button at the bottom.
- In the “System variables” section, scroll down and find the “Path” variable, then click on “Edit”.
- Click on “New” and add the path to the Python directory (e.g. C:\Python39).
- Click “OK” to save the changes and close all the windows.
Step 4: Restart the Command Prompt
After making changes to the system PATH environment variable, you need to close and reopen the Command Prompt for the changes to take effect.
Step 5: Test the Python Installation
To test if Python is working properly, open the Command Prompt and type “python” and press Enter. This should start the Python interpreter. You can also test by running a Python script.
If you follow these steps, you should be able to resolve the “couldnt launch Python exit code 9009” error message and start using Python on your system.
