Python raise child_exception OSError:[Errno 8] Exec格式错误

我必须将python脚本从使用Python 2.6的服务器移动到另一个使用2.4的服务器。

我不得不做一些修改。现在我卡住了。我继续收到此错误

 File "subprocess.py", line 975, in _execute_child
    raise child_exception
OSError: [Errno 8] Exec format error         

我的日志输出:

Traceback (most recent call last):
File "/cnfs/dev/regions/que/cli/rpntrans_requests/scripts/0.6a/process.py", line 281, in ?
process(filename)
File "/cnfs/dev/regions/que/cli/rpntrans_requests/scripts/0.6a/process.py", line 259, in process

errread, errwrite)
File "subprocess.py", line 975, in _execute_child
raise child_exception
OSError: [Errno 8] Exec format error

来自rpntrans.py的代码

    subprocess.call([
        os.path.join(module_root, 'bin/fst2r2c'),
        file,
        v_name, 
        str(r.ip2), str(r.ip2),
        out_file,
        '1', '0',
        '%s (ip1:%i)' % (self.dict[v_name]["desc"], r.ip1),
        self.dict[v_name]["units"],
        self.format,
        self.__get_interpolation(v_name)
    ],
        stdout=sys.stdout, stderr=sys.stderr
    )

任何人有想法吗?

谢谢

2 个答案:

答案 0 :(得分:15)

如果bin/fst2r2c是二进制可执行文件,它是新服务器的正确格式吗? (你是从Linux迁移到BSD,还是从32位迁移到64位?)

如果bin/fst2r2c是脚本,其#!行是否完好无损? (您是否在Windows上对其进行了编辑并引入了\r?新计算机上的可执行文件的路径名是否不同,例如/usr/bin/usr/local/bin?)

答案 1 :(得分:0)

首先从命令行运行要从subprocess调用的命令,看看它是否有效。比打印出你用Python生成的命令,即os.path.join(module_root, 'bin/fst2r2c'),看看是否看起来一样。
