Python子流程Exec格式错误 [英] Python subprocess Exec format error

问题描述

很抱歉，这个问题很愚蠢.我正在使用python subprocess 语句在Ubuntu(Natty 11.04)中调用.bat文件，但是，我收到了错误消息:

Sorry if this question is dumb. I am using python subprocess statement to call a .bat file in Ubuntu (Natty 11.04), however, I got error messages:

Traceback (most recent call last):
  File "pfam_picloud.py", line 40, in <module>
    a=subprocess.Popen(src2, shell=0)
  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

运行此python文件

$python pfam_picloud.py

Python代码(pfam_picloud.py)

#!/usr/bin/python
#
met="wTest.dvf"
run="run_pfam.bat"
inp="pfam_input.PFA"
import os
import stat
import shutil
import subprocess
import string
import random
# Generate a random ID for file save
def id_generator(size=6, chars=string.ascii_uppercase + string.digits):
    return ''.join(random.choice(chars) for x in range(size))
name_temp=id_generator()
cwd=os.getcwd()
src=cwd
src1=cwd+'/'+name_temp
if not os.path.exists(src1):
    os.makedirs(src1)
else:
    shutil.rmtree(src1)
    os.makedirs(src1)
##
shutil.copy(src+"/"+run,src1)
shutil.copy(src+"/"+met,src1)
shutil.copy(cwd+"/pfam_pi.exe",src1)
shutil.copy(src+"/"+inp,src1)
#
src2=src1+"/run_pfam.bat"
os.chdir(src1)
a=subprocess.Popen(src2, shell=0)
a.wait()

bash文件(run_pfam.bat)

#!/bin/sh
./pfam_pi.exe pfam_input.PFA

我可以在Ubuntu中成功运行此bash文件.所以我想我在Python脚本中弄乱了一些东西.有人可以给我一些建议吗?感谢您的投入.

I can successfully run this bash file in Ubuntu. So I guess, I messed up something in my Python script. Could anyone give me some suggestions? Thanks for any inputs.

文件 pfam_pi.exe 是Linux可执行文件.我在Ubuntu中编译它.抱歉造成混乱.

the file pfam_pi.exe is a Linux executable. I compiled it in Ubuntu. Sorry for the confusion.

好吧，我现在得到了不同类型的错误.1.用#！/bin/sh 表示没有这样的文件或目录.2.使用/bin/sh 表示 exec格式错误.3.如果我将所有内容作为参数发送 a = subprocess.Popen(['./pfam_pi.exe'，'inp'，'src1']，shell = 0)，它说 end线符号错误

Well, I got different types of error now. 1. With #!/bin/sh, it said No such file or directory. 2. With /bin/sh, it said exec format error. 3. If I sent everything as arguments a=subprocess.Popen(['./pfam_pi.exe', 'inp', 'src1'], shell=0), it said end of line symbol error

@Ellioh:谢谢您的评论.我发现一旦我更改了shell = 1，问题就解决了.– tao.hong
