I'm trying to get a Docker image up and running with Ubuntu 16.04 and Python 3.8 so I can build ROS2 Foxy, but I have a couple of problems with their modules, specifically with qt_gui_cpp:
--- stderr: qt_gui_cpp
Traceback (most recent call last):
File "/opt/ros/foxy/share/python_qt_binding/cmake/sip_configure.py", line 9, in <module>
import sipconfig
ModuleNotFoundError: No module named 'sipconfig'
make[2]: *** [sip/qt_gui_cpp_sip/Makefile] Error 1
make[1]: *** [src/qt_gui_cpp_sip/CMakeFiles/libqt_gui_cpp_sip.dir/all] Error 2
make: *** [all] Error 2
---
Failed <<< qt_gui_cpp [14.7s, exited with code 2]
And:
--- stderr: test2to3
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help
error: invalid command 'egg_info'
Failed <<< test2to3 [0.54s, exited with code 1]
In my various attempts, I've tried obvious stuff like this to install from scratch:
ENV NEW_PYTHON_BASE_VERSION=3.8
ENV NEW_PYTHON_VERSION=${NEW_PYTHON_BASE_VERSION}.0
RUN curl -L https://www.python.org/ftp/python/${NEW_PYTHON_VERSION}/Python-${NEW_PYTHON_VERSION}.tgz | \
tar xz && \
cd Python-${NEW_PYTHON_VERSION} && \
./configure --enable-optimizations && \
make altinstall && \
rm -rf Python-${NEW_PYTHON_VERSION}
RUN pip3 install -U setuptools sip ez_setup
But nothing seems to work. The answers for this similar question don't work for me either. Any suggestions as to where I should look?
