In this article, we’ll explore what causes this error and what steps you can take to resolve it.

Understanding the Error Message

First, let’s take a closer look at the error message itself. “Couldn’t Launch Python: Exit Code 9009” is a generic error message that can occur when attempting to launch Python from the command prompt or a shell script. The “exit code 9009” refers to a specific error code that indicates the command or program being executed was not found.

In other words, the error message is telling you that the system was unable to locate the Python executable. This can happen for a variety of reasons, which we’ll explore next.

Causes of the Error

There are several potential causes for the “Couldn’t Launch Python: Exit Code 9009” error. Some of the most common include:

  • Incorrect path: If the system is unable to find the Python executable, it may be because the path to the executable is incorrect or has not been properly set.
  • Missing Python installation: If Python is not installed on your system or is not installed correctly, you may encounter this error message.
  • Corrupted Python installation: If the Python installation on your system is corrupted or damaged, it may prevent the system from launching Python.
  • Conflicting Python installations: If you have multiple installations of Python on your system, they may be conflicting with each other and causing this error.

Resolving the Error

Fortunately, there are several steps you can take to resolve the “Couldn’t Launch Python: Exit Code 9009” error. Here are some potential solutions:

  1. Check the Path: Make sure the path to the Python executable is correct and has been added to your system’s PATH environment variable. You can check this by running “echo %PATH%” in the command prompt.
