python - 调试 Pycharm 'python_implementation' 时出错

问题描述

我在虚拟环境中使用 PyCharm 和 Python 3.6，并且在调试（而不是在运行时）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，因为我可以调试过去创建的其他文件，但无法调试新创建的任何脚本。

解决方案

我在这部分回溯中看到了一个问题：

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

模块subprocess 导入signal。一定是这个；在您的目录结构中，它必须是/usr/lib/python3.6/signal.py. 但相反，它尝试

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

我怀疑问题出在错误sys.path或$PYTHONPATH.
