This has been fixed after reinstalling python and the environment.

How did you solve it?

def packages(versions=False): import sys import subprocess try: venv_python_path = sys.executable result = subprocess.check_output([venv_python_path, '-m', 'pip', 'freeze'], stderr=subprocess.STDOUT) lines = result.decode(errors='replace').splitlines() return [line if versions else line.split('==')[0] for line in lines] except subprocess.CalledProcessError as e: print("An error occurred while fetching packages:", e.output.decode(errors='replace')) return []

为了避免 UnicodeDecodeError，你可以尝试在解码输出时使用 errors='ignore' 或 errors='replace'，这样可以忽略或替换无法解码的字节。
