设置 svnperms 预提交挂钩

我正在尝试将 svnperms 实现到存储库中，但在一些事情上遇到了困难：

pre-commit具有执行权限：

-rwxrwxr-x   1 svnadm     svn           3018 May 27 10:11 pre-commit

这是我在预提交中对 svnperms 的调用：

# Check that the author of this commit has the rights to perform
# the commit on the files and directories being modified.
SVNPERMS=/usr/local/svn/scripts/svnperms.py
$SVNPERMS -r $REPOS -t $TXN || exit 1

我已将 svnperms.py 安装在指定位置：

# ls -l /usr/local/svn/scripts
total 24
-rwxrwxr-x   1 svnadm     svn          11840 May 25 07:48 svnperms.py

svnperms.py 采用 UNIX 格式 - 没有 ^M 行结尾。

TortoiseSVN 回来了：

Command: Commit  
Modified: C:\projects\Sandbox\Trunk\Test.txt  
Sending content: C:\projects\Sandbox\Trunk\Test.txt  
Error: Commit failed (details follow):  
Error: 'pre-commit' hook failed with error output:  
Error: No such file or directory: python  

调用不带参数的精子显示：

/usr/local/svn/scripts/svnperms.py
missing required option(s): repository, either transaction or a revision
Usage: svnperms.py OPTIONS

Options:
    -r PATH    Use repository at PATH to check transactions
    -t TXN     Query transaction TXN for commit information
    -f PATH    Use PATH as configuration file (default is repository
               path + /conf/svnperms.conf)
    -s NAME    Use section NAME as permission section (default is
               repository name, extracted from repository path)
    -R REV     Query revision REV for commit information (for tests)
    -A AUTHOR  Check commit as if AUTHOR had commited it (for tests)
    -h         Show this message

UNIX 管理员最近安装了 python，但不确定所有依赖项是否都存在。如果这是问题所在，我不确定如何确定，因为 python 似乎是根据上面的输出工作的。

我缺少什么？

我的猜测是python二进制文件不在$PATH对于 svn 服务器。沙邦线svnperms.py reads:

#!/usr/bin/env python

但这假设可执行文件位于$PATH来电者的。如果您无权修改 Subversion 服务器的运行时环境，请尝试替换python在 shabang 线上，路径为which python当你交互运行它时。
