Why can there be bugs with Git in cygwin?

Question

git

Strange thing: I install dependencies for the project (I call npm i), I see a bunch of errors in Cygwin with a message about cloning problems and completely insane paths. I do the same in Gitbash - everything works fine.
I use Cygwin and Gitbash from cmder
by calling git --version I see for Cygwin: git version 2.4.5, for Gitbash: git version
1.9.5.msysgit.1 , actually) worked correctly in Cygwin?
An example of an error log issued by Cygwin:

$ npm i

Cygwin does not use Windows-style absolute paths with drive.
He will not understand what C:\Users\... is.
Instead, you need to write /cygdrive/c/Users/....
What he tried to tell you about in the second error message in a veiled form.
