Cocos2d 3.17 prebuilt not working

I have cocos2d up and running, except, the prebuit libraries are not working. When I run cocos gen-libs -p win32 -vs 2015 -m debug it runs, and creates a prebuilt folder. However, this prebuilt folder only contains an empty win32 folder.

It outputs this huge thing (see final build results at bottom):

MSBUILD : error MSB1009: Project file does not exist.

Error running command, return code: 1.

When I then go into the prebuilt/win32 folder that was generated, it is completely empty. Why?

What are all the Xarmian errors?

I have absolutely no idea, I’ve never even used Xarmian in my entire life, I barely even know what it is.

I looked the errors up, and it seems like they aren’t really that bad. They are simply messages.
Here’s where I found that out: https://help.appveyor.com/discussions/problems/4569-the-target-_convertpdbfiles-listed-in-a-beforetargets-attribute-at-c-does-not-exist-in-the-project-and-will-be-ignored
