pi@raspberrypi:~ $ python3 --version
Python 3.6.5

pi@raspberrypi:~ $ sudo apt-get install python3-pyqt5

Python 3.6.5 (default, Jul  4 2019, 01:11:28)
[GCC 4.9.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt5 import QtCore
Traceback (most recent call last):

我的导入语句是否错误？包裹还有别的名字吗？

Answer 1

否，您的导入语句没有错。不，（apt或pip）包未命名。但是，Python 3.6.5不是Python 3 version that shipped with Debian Jessie，而是Python 3.4.2。
