Vim cannot be used normally in cygwin.

I really don't want to install a VPC on my limited-memory machine, so it is a good choice to install cygwin. But I don't know why Vim cannot be used after I install it. The cursor is always at the beginning and does not go forward at all. I am still a beginner in Linux. I think Vim is so difficult to use. No wonder the Linux talent salary is too high, khhe .. But when I was on a business trip, I used my computer and installed Vim with no problems at all. It was very convenient to use. After I came back, I knew that my computer would still not work, it has its own weirdness. I have never had a good solution for Baidu, Google, and for a long time. Finally, we can see such a passage on a webpage today,

Vim of cygwin does not work. vim of cygwin does not work always although I reinstall it usually times. the cursor does not move any more. it just remain the left-top.but gvim of command line for w2k works well. why? I got the answer from Rick. The reason is because system envionment variables of Rational Rose conflict. I have to modify the cygwin. BAT to clear those conflicted system envionment variables. Set Home =
Set term =
Set termcap =
Set terminfo = I wonder how Rick know this reason and I cocould not search the answer from Google. "I changed the address of the term, termcap, and terminfo according to the method. As a result, VIM became normal, and VIM was in conflict with Rose. It was really strange. We hope that other people can solve such problems smoothly. Finally, thank you. Article The author, and the Rick he mentioned!
