命令行执行learntris.py遇Permission Denied但仍有输出问题求助

Hey there! Let's work through this issue step by step to get your learntris.py running as expected.

1. Resolve the "Permission Denied" Error #

This is almost always a file permissions issue on Unix-like systems (Linux/macOS). Here's how to fix it quickly:

• First, grant executable permissions to your script with this command:

  chmod +x learntris.py
  

• Next, add a shebang line to the very top of your learntris.py file. This tells your system which interpreter to use to run the script:

  #!/usr/bin/env python3
  

  Without this line, even with executable permissions, your system might not know how to execute the Python script properly.

If you don't want to tweak permissions right now, you can also bypass this by running the script directly via the Python interpreter:

python3 learntris.py

2. Troubleshooting Unexpected Output #

Now, let's tackle the mismatched output issue. Here are a few common checks:

• Verify the file is truly empty: The project asks for an empty learntris.py—accidental whitespace or hidden characters can throw off results. You can confirm with:

  cat learntris.py
  

• Double-check your execution command: Are you running the exact command the README specifies? For example, if the project expects ./learntris.py, make sure you're in the correct directory when running it.
• Compare expected vs actual results: If the expected output is a specific test failure or error message from the project's harness, ensure you haven't skipped any setup steps (like installing dependencies or launching the test suite alongside your script).

Quick Recap #

1. Add executable permissions with chmod +x learntris.py
2. Add the shebang line to the top of your script
3. Confirm the file is empty and you're using the correct execution command

If you still see mismatched output after these steps, share the exact expected output and what you're seeing—we can dig deeper!
