Jetson nano 无法安装 PyQt5

Question

我正在努力在我的 Jetson nano 中安装 PyQt5。然而，有一件事总是让我烦恼。 这是反馈信息。

        ERROR: Failed building wheel for sip
      Failed to build sip
      ERROR: Could not build wheels for sip, which is required to install pyproject.toml-based projects

我尝试过

sudo pip3 install pyqt5

，它给了我

compilation terminated.
            error: command '/usr/bin/aarch64-linux-gnu-gcc' failed with exit code 1
            [end of output]

我也尝试过

sudo apt-get install python3-pyqt5

。它有效，但是当我通过

from pyqtgraph.Qt import QtCore, QtGui

或

from PyQt5.QtCore import QObject, pyqtSignal

导入 PyQt5 时，它给了我

Traceback (most recent call last):
  File "/home/llw/Desktop/project/ture file/save_pointcloud.py", line 16, in <module>
    from pyqtgraph.Qt import QtCore, QtGui
  File "/usr/local/lib/python3.7/dist-packages/pyqtgraph/__init__.py", line 17, in <module>
    from .colors import palette

  File "/usr/local/lib/python3.7/dist-packages/pyqtgraph/Qt/__init__.py", line 155, in <module>
    import PyQt5.QtCore
ModuleNotFoundError: No module named 'PyQt5.QtCore

如何解决这个问题？任何建议或想法都可能有所帮助。

谢谢你。
