Complete output from command python setup.py egg_info:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/lib/python3.6/tokenize.py", line 452, in open
buffer = _builtin_open(filename, 'rb')

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-b2zw891b/PyQt5/
然后我从https://www.riverbankcomputing.com/software/pyqt/download5下载了zip文件夹并运行:
python3 configure.py --qmake /home/oo/Qt/5.14.0/gcc_64/bin/qmake
make
sudo make install
成功
>>> import PyQt5
>>> import PyQt5.QtCore
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'PyQt5.sip'
>>>
于是我安装了
pip3 install PyQt5.sip
pip3 install sip
成功
但仍然出现相同的错误 No module named 'PyQt5.sip'
,用于 import PyQt5.QtCore
还尝试了PyQtChart,但仍有错误
pip3 install PyQtChart

我还从https://www.riverbankcomputing.com/software/pyqtchart/download下载了压缩文件,然后运行:
python3 configure.py --qmake /home/oo/Qt/5.14.0/gcc_64/bin/qmake
Error: Unable to import PyQt5.QtCore. Make sure PyQt5 is installed.
我的最终目标是使用 pyqt5 运行蜡烛图。
sudo python3 -m pip install pyqt5 pyqtchart

Requirement already satisfied: pyqt5 in /usr/lib/python3/dist-packages

Requirement already satisfied: PyQt5-sip<13,>=12.7 in /home/oo/.local/lib/python3.6/site-packages (from pyqtchart)
但仍然收到相同的错误:

中的所有PYQT包都删除了,然后安装了pyqt5 pyqtchart pyqt5.sip sip
但是在导入PyQt5.QtCore
时仍然出现错误ModuleNotFoundError: No module named 'PyQt5.sip'
