安装plotly.graph_objects后所有Python程序均报路径错误求助

问题

安装plotly.graph_objects后,运行任何Python程序(包括简单print语句)都会触发Error determining module path for sys.argv错误,卸载模块后问题依旧。报错详情:

E+00000.063: Error determining module path for sys.argv

             Traceback (most recent call last):

解决步骤
  • 修正VS Code调试配置:打开项目下的.vscode/launch.json,检查program字段值。如果之前错误设置为plotly==5这类带版本号的模块名,改为实际要运行的脚本路径,比如${file}表示当前打开的文件。
  • 重置Python环境选择:点击VS Code左下角的Python解释器版本,重新选择正确的本地Python环境,确保环境未关联残留的模块配置。
  • 清理调试工具缓存:删除c:\Users\User\.vscode\extensions\ms-python.python-2023.4.1\pythonFiles\lib\python\debugpy目录下的临时缓存文件,或者直接卸载并重装VS Code的Python扩展。
  • 彻底清理模块残留:打开命令行执行pip list查看是否还有plotly相关条目,若有则运行pip uninstall plotly完全卸载,同时手动删除Python安装目录下site-packages文件夹中所有plotly相关的文件和文件夹。
