    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')
    FileNotFoundError: [Errno 2] No such file or directory: '/tmp/pip-build-b2zw891b/PyQt5/setup.py'

    ----------------------------------------
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'
>>> 

所以我安装了

pip3 install PyQt5.sip
pip3 install sip

成功

但对于No module named 'PyQt5.sip'，仍然出现相同的错误import PyQt5.QtCore

也尝试过PyQtChart，但仍然出错

pip3 install PyQtChart

我还从https://www.riverbankcomputing.com/software/pyqtchart/download下载了zip文件夹并运行：

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.

QT屏幕截图：：

我的最终目标是使用pyqt5运行烛台图。

sudo python3 -m pip install pyqt5 pyqtchart
[sudo] password for oo:

Answer 1

复制main.py中my previous answer的示例，然后运行：

python3 main.py

我建议您搜索失败尝试生成的文件夹和文件，然后将其删除。

为了测试，我使用了以下Dockerfile

Answer 2

通过pip3 install --upgrade pip将点更新为最新值

安装先前版本，该版本使用了许多linux1（pip3 install pyqt5==5.14.0）
