我想你在 svn/project1、svn/project2 中的每一个中都有一个 SVN 存储库，svn/project3 -- 并且您在 svn 中没有与 SVN 相关的任何内容.

I suppose you have one SVN repository in each one of svn/project1, svn/project2, svn/project3 -- and that you have no SVN-related anything in svn.

您可以在浏览器中看到 svn 的内容，因为该目录是由您的网络服务器提供的——但它不是作为与 SVN 相关的东西提供的:它只是一个发送给您的 HTML 页面浏览器.

You can see the content of svn in a browser because that directory is served by your webserver -- but it's not served as an SVN-related thing : it's just an HTML page that's sent to your browser.

因此，TortoiseSVN 无法使用它:svn 不是 SVN 存储库.

As such, TortoiseSVN cannot work with it : svn is not an SVN repository.
