python - os.mknod() 在 MacOS 上失败？

Question

os.mknod() 是 Mac 上的特权调用吗？总是失败，不允许操作？

In [1]: import os

In [2]: os.mknod("/tmp/test123")
---------------------------------------------------------------------------
OSError                                   Traceback (most recent call last)
<ipython-input-2-1b8032a076af> in <module>()
----> 1 os.mknod("/tmp/test123")

OSError: [Errno 1] Operation not permitted

Mknod() requires super-user privileges.

除无效参数外均有效

sudo python -c "import os; os.mknod('/tmp/test123')"
