我正在尝试使用svnsync. 它在一个目标服务器上工作，但在另一个非常相似的设置上失败，我找不到有什么不同。两种情况下的源服务器都是相同的，所以我猜它的设置是无关紧要的。
目标服务器是：Windows Server 2008 R2 Standard SP1，64 位
SVN 是：VisualSVN Server 2.5.9（也试过 2.5.7 和 2.5.8）
svnsync 初始化失败：
E:\>svnsync init https://.../ https://.../
svnsync: E175002: DAV request failed; it's possible that the repository's pre-revprop-change hook either failed or is non-existent
svnsync: E175008: At least one property change failed; repository is unchanged
svnsync: E175002: Error setting property 'svn:sync-lock': Failed to start '.../hooks/pre-revprop-change.bat' hook
Hook 存在且仅包含 1 行：
E:\>type ...\hooks\pre-revprop-change.bat
exit 0
（相同的钩子适用于另一台目标服务器）
查看 Windows 中的事件查看器，我在 VisualSVN 服务器日志中看到以下错误：
Failed to start '.../hooks/pre-revprop-change.bat' hook [500, #165001]
[client 2002:f8d:64d6::f8d:64d6]
Can't start process '.../hooks/pre-revprop-change.bat': Invalid argument [500, #22]
[client 2002:f8d:64d6::f8d:64d6]
使用的 svnsync 版本：
E:\>which svnsync
D:\Program Files (x86)\VisualSVN Server\bin\svnsync.EXE
E:\>svnsync --version
svnsync, version 1.7.9 (r1462340)
