python 子进程抛出错误 "no such file or direcrory"

Question

s=subprocess.Popen(['/home/karthik/Downloads/stanford-parser-2011-06-08/lexparser.csh','-'],stdin=subprocess.PIPE,stdout=subprocess.PIPE,stderr=subprocess.PIPE)

Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/usr/lib/python2.7/subprocess.py", line 672, in __init__
        errread, errwrite)
      File "/usr/lib/python2.7/subprocess.py", line 1213, in _execute_child
        raise child_exception
    OSError: [Errno 2] No such file or directory

我确定此文件存在并且使用此文件名的 open() 有效。为什么我会收到此错误？我使用 python 2.7

确保 csh 已安装并且位于 /bin/csh 中(否则在 lexparser.sh 中的 shebang 之后编辑命令)。
