Python脚本：在Shell中运行但在现实生活中失败，因为无法导入模块 [英] Python Script: Runs in Shell but fails in real life because cant import module

问题描述

我有一个在Python Shell中运行良好的脚本，但是当双击它时无法导入PIL模块（但它确实导入了Shell中的PIL模块）。

I have a script that runs fine in the Python Shell, but when double clicked it fails to import the PIL module(but it does import the PIL module in the Shell).

有什么问题？我需要一个不同的shebang吗？我在Windows 7上：

What is wrong? Do I need a different shebang? I am on Windows 7:

#!/usr/bin/env python
"""

"""

try:
    from   PIL import Image
    import os
    import datetime
    import time

except Exception, e:
    raw_input(str(e))

# Running this script in the Shell, the code gets to here
# Running this script in real life (just double click it) it prints "no module PIL"

推荐答案

添加行

import sys
print sys.executable

到你的代码。你会在shell中运行它时看到它是一个不同的python可执行文件，而不是双击.py文件。

to your code. You'll see that it's a different python executable when you run it in the shell, vs. double clicking the .py file.

如果你想控制哪个安装版本python用于运行脚本，而不是简单地运行脚本，在Windows命令窗口中键入如下内容。

If you want to control which installed version of python is used to run your script, rather than simply running the script, type something like the following in a windows command window.

c:\python27\python.exe scriptname.py

替换python目录和脚本名称适当的。

replacing the python directory and script name as appropriate.
