我在虚拟环境中使用 PyCharm 和 Python 3.6，在调试（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

AttributeError: module 'platform' has no attribute 'python_implementation'

我的 Python 安装似乎正确，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1】：

我发现这部分回溯有问题：

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

模块subprocessimports signal。必须是this one；在您的目录结构中，它必须是/usr/lib/python3.6/signal.py。但它反而会尝试

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

我怀疑问题出在sys.path 或$PYTHONPATH 上。

【讨论】：

好收获。问题也可能是错误的工作目录，它在库上方提供了导入首选项。
我明白了，我将 CPython 模块中的名称与我项目中的脚本混淆了，如果我不想更改项目中脚本的名称，我该怎么办？（因为它是一个克隆的仓库）
如果是脚本或顶级模块，除了重命名别无他法。脚本或用户创建的顶级模块或包不得掩盖 Python 模块/包。永远不要将脚本、模块或包命名为 email、test 等。如果它不是顶级模块 - 从 $PYTHONPATH 中删除其目录。
