<!-- Please use this template while reporting a bug and provide as much info as possible. Not doing so may result in your bug not being addressed in a timely manner. Thanks!--I was trying to use a different editor than notepad on windows to be used by by setting the environment variable. Doing this was non trivial and the following did not work all resulting in different errors. What happened: What you expected to happen: I should be able to use normal windows paths, either by quoting them, or not. the workaround is to use a short filename however short paths are optional and may not always be created. () How to reproduce it (as minimally and precisely as possible): try and set an editor on windows where there is a space in the name of the command. Anything else we need to know?: Environment: Kubernetes version (use ): v1.10.3 Cloud provider or hardware configuration: N/A this is client side issue OS (e.g. from /etc/os-release): windows 10 1803 Kernel (e.g. ): :-) Install tools: Others:

In case anyone wants an answer, it needs two things: (or ) into system PATH environment variable EDITOR=notepad2 -w (or EDITOR=code -w)
Currently there is no way how to pass path with spaces on Windows with or environment variables. Pull Request addresses this issue. With the fix, you would be able to specify the following: and when is in your , you could do as well: or (this is current workaround for the problem)
