Python程序将在Spyder终端中运行,但不能在常规的Linux终端中运行

(我使用的是ubuntu 12.04)

我制作了这个python程序:

#!/bin/sh
# -*- coding: utf-8 -*-

import os

print "Multiple Command Runner"
print "<Made by Matthew Cherrey>"
print "-------------------------"
numbcommand = 0
allcoms = []
while 1:
    numbcommand = numbcommand + 1
    command = raw_input(" Command: ")
    allcoms.append(command)
    decide = raw_input("Press [Enter] to and another command, press [r] to run all commands: ")
    if decide == "r":
        break

commands = ""
first = True
for item in allcoms:
    if first:
        commands = item
    else:
        commands = commands + " && " + item
os.system(commands)

我希望能够在终端中运行它。我使用python编辑器:Spyder这个选项可以“在系统终端中运行”。每当我这样做,我的程序就完美无缺。我可以输入多个命令,并让它们全部运行。当我将文件设置为exicutible并运行/home/matthew/.runallcommands.py --python/home/matthew/.runallcommands.py时,首先将光标变为“t”,然后当我点击某些内容时,将拍摄该屏幕的某个区域并保存它是我家文件夹中名为“OS”的照片。然后我收到此错误消息:

matthew@matthew-MS-7721:~$ /home/matthew/.runallcommands.py --python
Warning: unknown mime-type for "Multiple Command Runner" -- using "application/octet-stream"
Error: no such file "Multiple Command Runner"
Warning: unknown mime-type for "<Made by Matthew Cherrey>" -- using "application/octet-stream"
Error: no such file "<Made by Matthew Cherrey>"
/home/matthew/.runallcommands.py: 13: /home/matthew/.runallcommands.py: numbcommand: not found
/home/matthew/.runallcommands.py: 14: /home/matthew/.runallcommands.py: allcoms: not found
/home/matthew/.runallcommands.py: 17: /home/matthew/.runallcommands.py: Syntax error: "(" unexpected (expecting "do")

我不确定它是否与我调用文件的方式有关,因为我的程序在spyder的终端中工作率100%。

答案 0 :(得分:1)

第一行指示系统使用Bourne shell运行它,而不是使用Python解释器。

更改

#!/bin/sh

类似

#!/usr/bin/env python

当您从Python IDE运行它时,IDE知道它是一个Python脚本,因此它显式调用Python解释器,绕过第一行的指令。
