類型錯誤： '海峽' 對象不是可調用（Python的2.4.3）

Question

當我嘗試在Python 2.4.3運行下面的腳本，我得到錯誤：

[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

但相同的腳本，當關於Python 2.7.3運行沒有給出錯誤。

您使用的exit內建文件沒有記錄，不應使用，並且在不同的Python版本上顯然行爲不同。您應該使用適當的print陳述和sys.exit。
