git svn clone无法获取代码-PHP 중국어 네트워크 Q&A

在gitlab上创建了一个project, 然后在linux 里 git svn clone project_svn_url, 最后成功push到gitlab上。
但是，在gitlab上把这个project 删除了，再创建了一个同名 project,
又在linux 上重做 git svn clone，再也得获取不了代码，只得到一个空目录，已经确定svn 上有代码的.
不知怎么回事. 求助各位，谢谢

admin$ git svn clone http://project_svn_url --no-metadata --authors-file=author.txt

完了之后只是个空目录
