如何解決這個問題？ SVN 1.8.19：E170000：無法識別的URL方案

Question

我想在我的Linux服務器（SUSE Linux Enterprise Server 11）上使用svn，並安裝svn 1.8.19，但是當我使用：svn update時，問題出現：

svn: E170000: Unrecognized URL scheme for 'http://.....' 

這些信息來源爲SVN：

svn, version 1.8.19 (r1800620) 
compiled Aug 31 2017, 16:07:39 on x86_64-unknown-linux-gnu

以下的版本庫訪問（RA）模塊：

* ra_svn : Module for accessing a repository using the svn network protocol. 
    - handles 'svn' scheme 
* ra_local : Module for accessing a repository on local disk. 
    - handles 'file' scheme 

然後我找出我需要安裝scons的-2.5.1和農奴-1.3.9，但我安裝scons的-2.5.1後，我得到了一個錯誤：

你svn客戶端未建立與支持爲http和https。它缺少添加http和https支持的serf（libserf）庫。
