当我尝试在 Python 2.4.3 中运行以下脚本时，出现错误：
[root@localhost bin]# ./clokins.py
Traceback (most recent call last):
File "./clokins.py", line 162, in ?
print main(argv)
File "./clokins.py", line 156, in main
cloc = cloc_cmdline(fpath, arguments[1:])
File "./clokins.py", line 118, in cloc_cmdline
(binary, cloc_opts) = readopts(cmdarg)
File "./clokins.py", line 108, in readopts
exit('File does not exists : %s'%(options.clocpath))
TypeError: 'str' object is not callable

但同样的脚本，在 Python 2.7.3 上运行时不会出错。
