.gitignore被Git忽略

问题：

My .gitignore file seems to be being ignored by Git - could the .gitignore file be corrupt? 我的.gitignore文件似乎已被Git忽略.gitignore文件是否已损坏？ Which file format, locale or culture does Git expect? Git需要哪种文件格式，语言环境或文化？

My .gitignore : 我的.gitignore ：

1# This is a comment
2debug.log
3nbproject/

Output from git status : 从git status输出：

1# On branch master
2# Your branch is ahead of 'origin/master' by 1 commit.
3#
4# Untracked files:
5#   (use "git add <file>..." to include in what will be committed)
6#
7#       debug.log
8#       nbproject/
9nothing added to commit but untracked files present (use "git add" to track)

I would like debug.log and nbproject/ not to appear in the untracked files list. 我希望debug.log和nbproject/不会出现在未跟踪的文件列表中。

Where should I start looking to fix this? 我应该从哪里着手解决此问题？
