[yzbf-lin]

在subprocess.check_call()中添加shell=True参数，解决Windows系统下 执行python.exe ensurepip --upgrade时出现CalledProcessError(returncode 2)的问题

🔧 Technical Details

Before:

subprocess.check_call([
    'D:\\path\\to\\.venv\\Scripts\\python.exe',
    '-m','ensurepip','--upgrade'
])
# ❌ Fails with CalledProcessError (returncode 2)

**Afater:**
subprocess.check_call([
    'D:\\path\\to\\.venv\\Scripts\\python.exe',
    '-m','ensurepip','--upgrade'
], shell=True)
# ✅ Works correctly on Windows
