执行Python脚本出现NativeCommandError，请求排查代码及环境问题

Hey there, let's dig into what's causing this issue with your code! First off, I spotted a straightforward syntax mistake that's almost certainly the root of the problem you're seeing.

The Critical Syntax Error #

Take a look at this line in your script:

matches.append(os.path.join(root, filename)

You're missing a closing parenthesis at the end! It should be written as:

matches.append(os.path.join(root, filename))

This syntax error stops the Python interpreter from properly parsing and running your script. On Windows (especially in PowerShell), when a Python script fails to execute due to a syntax issue, it can sometimes get wrapped into a NativeCommandError instead of showing the direct Python syntax error message—this is why you're seeing that specific error type.

Checking Other Potential Factors #

You mentioned you've set up Notepad++ with 4-space indents (no tabs) using the Python indent plugin, which is great—indentation isn't the problem here. That part of your setup is totally correct.

Corrected Full Code #

Here's the fixed version of your script, with a small readability improvement:

import os
import fnmatch

# Replace these with your actual values
rootPath = "C:/your/target/directory"
pattern = "*.txt"  # Example pattern, adjust to your needs
matches = []

for root, dirs, files in os.walk(rootPath):
    for filename in fnmatch.filter(files, pattern):
        full_file_path = os.path.join(root, filename)
        matches.append(full_file_path)
        print(full_file_path)

Additional Checks (If the Error Persists) #

If fixing the syntax error doesn't resolve the NativeCommandError, double-check these details:

• Ensure rootPath is a valid directory you have read access to on your system.
• Verify your pattern uses correct fnmatch syntax (e.g., *.py for Python files, *log*.csv for CSV files with "log" in the name).
• Make sure you're running the script with the right terminal command—use python your_script.py or py your_script.py (Windows-specific shorthand) to launch it.
