Can some one help me out on windows with this problem????
回答1:
Not sure is this is the same problem or not, if it's - up vote my answer, if not - just continue to search.
When debugging with visual studio or visual code - visual studio keep logs of debugging session in file %TEMP%\vscode-node-debug2.txt.
It's indeed long log text, which is difficult to read and moreover understand what went wrong. But in my case I've found following log entry (somewhere close to the end of log):
↠From target: {"method":"Runtime.consoleAPICalled","params":{"type":"error","args":[{"type":"string","value":"WebpackO
ptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does
not match the API schema.\n - configuration.context: The provided value \"D:\\\\!deleteme!\\\\VuejsApp1\\\\VuejsApp1\" co
ntains exclamation mark (!) which is not allowed because it's reserved for loader syntax.\n -\u003E The base directory
There were also a lot of EMFILE log entries, but they were not a root cause of failure.
Root cause in my case was that I have used special character in path - D:\!deleteme!\VueJsApp - and I have fixed it by simply creating directory without exclamation mark.
I was still not being able to debug VueJsApp - I suspect due to .vue to .js conversions, but normal javascript was possible to debug still.
