Question

我正在尝试在Python中执行以下代码

import os,subprocess
from glob import glob

path = "/Users/armed/private_SDKs"
os.chdir(path)

for file in glob("*.framework"):
     command = ['class-dump' , '-H' , file , '-o' , '~', '/Users/armed/Desktop/Headers/']
     subprocess.call(command)

执行此脚本时，我收到以下错误： -

Traceback (most recent call last):
  File "<pyshell#52>", line 3, in <module>
    subprocess.call(command)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 493, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 679, in __init__
    errread, errwrite)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1228, in _execute_child
    raise child_exception
OSError: [Errno 13] Permission denied

非常感谢任何帮助！

检查class-dump命令的权限。 chmod +x class-dump如果它不可执行。以下是chmod上的文档。

如果它不在您的路径上，您可能还需要指定类转储的绝对路径。

另外，试试：

print " ".join(command)

并查看是否可以通过将结果粘贴到shell中来运行它。
