pydev 调试器在启动时失败，但代码运行良好 [英] pydev debugger fails on launch but code runs fine

问题描述

当我使用 LiClipse(两者的最新版本)启动 pydev 调试器时，出现KeyError:"异常.

When I launch the pydev debugger with LiClipse (latest versions of both) I get a "KeyError:" exception.

我已确保工作区文件夹具有适当的权限.即使我在管理员模式下运行 LiClipse，我也会遇到这个问题.

I have ensured that the workspace folder has the proper permissions. I get this problem even if I run LiClipse in Administrator mode.

我希望能够调试我的 Python 代码.我的实际结果是以下错误:

I expect to be able to debug my python code. My actual results are the following errors:

pydev debugger: starting (pid: 15388)

During handling of the above exception, another exception occurred:

推荐答案

当我发布这个问题时，我注意到用作键的文件名和实际文件路径存在大小写差异.我将工作区移至 C 驱动器的根目录，这似乎解决了问题.

While I was posting this question I noticed that there is a capitalization difference with the file name being used as the key and the actual file path. I moved the workspace to the root of my C Drive and that seems to have fixed the problem.
