Solve Python error: subprocess-exited-with-error

If you're a Python developer, you may have encountered a subprocess error at some point. One of the most common subprocess errors is "subprocess-exited-with-error." This error occurs when a subprocess running in your Python code exits with an error. The error message usually includes information about the subprocess and the error code.

This article will provide you with some tips and techniques to help you resolve "subprocess-exited-with-error" errors in Python. We'll discuss the common causes of this error, how to diagnose it, and how to fix it.

What Causes "subprocess-exited-with-error"?

Usually, "subprocess-exited-with-error" occurs when a process that has been spawned by Python ends with an error code. This may happen due to a number of reasons such as:

  • Incorrect parameters or arguments passed to the subprocess.
  • Insufficient permissions or lack of privileges to access certain resources.
  • A bug in the program being executed by the subprocess.
  • A syntax or runtime error in the program being executed.
  • An issue with the environment variables that the subprocess is running in.

Diagnosing "subprocess-exited-with-error"

To diagnose this error, you'll need to start by examining the error message. The error message is usually displayed on the console, and it contains information about the error code, the subprocess, and the command that was being executed. The error message may also contain information about the arguments that were passed to the process.

Once you've examined the error message, you can start debugging your code. You may want to use a debugger to step through your code and identify any issues that are causing the error.

Fixing "subprocess-exited-with-error"

There are several steps you can take to fix "subprocess-exited-with-error." Here are some tips and techniques that may help you resolve this issue:

Check Your Arguments and Parameters

One of the most common causes of "subprocess-exited-with-error" is incorrect arguments or parameters passed to the subprocess. Make sure that you're passing the correct arguments and parameters to the subprocess. If the subprocess is expecting a parameter, make sure that you're passing it in the correct format.

Check File Permissions

If the subprocess is accessing files or resources that require administrative privileges, it may fail if it doesn't have the proper permissions. Make sure that the subprocess has the necessary permissions to access the files and resources it needs.

Check for Syntax and Runtime Errors

If the error code is related to syntax or runtime errors, you'll need to review the program being run by the subprocess. Check for syntax errors, misplaced characters, or other issues that may be causing the code to fail.

Review Your Environment Variables

If the error code is related to environment variables, you'll need to check the variables being passed to the subprocess. Make sure that the variables are consistent with the environment in which the subprocess is being run.

Use a Debugging Tool

If you're having difficulty resolving "subprocess-exited-with-error," you may want to use a debugging tool to help you identify the issue. You can step through your code to identify issues that may be causing the subprocess to fail.


"Subprocess-exited-with-error" can be a frustrating error to deal with, but the good news is that it's usually easy to diagnose and fix. By following the tips and techniques outlined in this article, you should be able to resolve this error quickly and get back to writing great Python code.

Remember to check your arguments and parameters, review your environment variables, and use a debugging tool if needed. With a little persistence and effort, you can solve "subprocess-exited-with-error" and continue building awesome Python applications.
