svn commit出错，怎么回事？
P:\Monica\svntemp\test>svn commit
svn: Commit failed (details follow):
svn: Could not use external editor to fetch log message; consider setting the $S
VN_EDITOR environment variable or using the --message (-m) or --file (-F) option
s
svn: None of the environment variables SVN_EDITOR, VISUAL or EDITOR are set, and
no 'editor-cmd' run-time configuration option was found
下面一堆什么玩意儿，以前没有遇到这种错误的啊？
需要外部编辑器干什么？
P:\Monica\svntemp\test>svn commit -m "up" // 加-m选项后，是另外错误。。 也没提示让我输入账号密码啊。。。svn: Commit failed (details follow):
svn: Authorization failed
