调试Pycharm“python\u实现”时出错

Question

我在虚拟环境中使用PyCharm和Python 3.6，在调试（而不是运行）脚本时出现以下错误：

/home/developer/master/bin/python3 /snap/pycharm-community/155/helpers/pydev/pydevd.py --multiproc --qt-support=auto --client 127.0.0.1 --port 34977 --file /home/developer/motionplanningthesishector/Planner/control/studywolf_control/controllers/ilqr_truck.py

    IS_PYPY = platform.python_implementation() == 'PyPy'
AttributeError: module 'platform' has no attribute 'python_implementation'

我的Python安装似乎是正确的，因为我可以调试我在过去创建的其他文件，但不能调试任何新创建的脚本。你知道吗

在回溯的这一部分我发现了一个问题：

  File "/usr/lib/python3.6/subprocess.py", line 50, in <module>
    import signal

模块subprocessimports ^{}。它必须是this one；在目录结构中，它必须是/usr/lib/python3.6/signal.py。但它却在尝试

  File "/home/developer/motionplanningthesishector/Planner/control/studywolf_control/controllers/signal.py", line 18, in <module>

我怀疑问题出在错误的sys.path或$PYTHONPATH。你知道吗
