我在使用 Python 在我的 Linux 机器上查找可用的可执行文件时遇到问题。我的默认 PATH 包含此可执行文件（svnlook），但是当我运行 python 脚本时，以下函数无法找到可执行文件。有想法该怎么解决这个吗？

def command_output(cmd):
    child  = subprocess.Popen(cmd.split(), stdout=subprocess.PIPE)
    output = child.communicate()[0]
    return output, child.returncode


def get_author():
    cmd = "svnlook author %s %s %s" % (svn_opt, svn_txn, svn_repo)
    author, return_code = command_output(cmd)

    return author.strip()

错误：

 Traceback (most recent call last):
  File "/home/user/app/csvn/data/repositories/repo/hooks/pre-commit", line 82, in <module>
    author = get_author()
  File "/home/user/app/csvn/data/repositories/repo/hooks/pre-commit", line 53, in get_author
    author, return_code = command_output(cmd)
  File "/home/user/app/csvn/data/repositories/repo/hooks/pre-commit", line 36, in command_output
    child  = subprocess.Popen(cmd.split(), stdout=subprocess.PIPE)
  File "/home/user/app/activepython-2.7.2.5_x86_64/lib/python2.7/subprocess.py", line 679, in __init__
    errread, errwrite)
  File "/home/user/app/activepython-2.7.2.5_x86_64/lib/python2.7/subprocess.py", line 1228, in _execute_child
    raise child_exception

您可能希望提供可执行文件的完整路径，例如，/usr/bin/svnlook或者/usr/local/bin/svnlook不仅仅是svnlook.

尝试从控制台运行它。确保权限/可执行性正确。试试 os.system()。
