当我在Windows上使用脚本名称运行Python脚本时,无法重定向输出 [英] Cannot redirect output when I run Python script on Windows using just script's name
问题描述
这是运行在Windows 7(64位),Python 2.6与Win32扩展为Python。
我有一个简单的脚本只打印hello world。我可以用 python hello.py
启动它。在这种情况下,我可以将输出重定向到一个文件。但是如果我通过在命令行上输入 hello.py
并重定向输出来运行它,我会得到一个异常。
C:> python hello.py
hello world
C:> python hello.py>输出
C:>类型输出
hello world
C:> hello.py
hello world
C:> hello.py>输出
在文件对象析构函数中关闭失败:
sys.excepthook中的错误:
原始异常为:
我想我升级到Windows 7后首先得到这个错误。我记得它应该在XP中工作。我看到有人在讨论这个错误 python-Bugs- 1012692 |不能管道输入到python程序。但这是很久以前。它没有提及任何解决方案。
有没有人遇到过这个?
在命令行上执行Python脚本时(即从script.py而不是python script.py开始),
重定向可能无法工作,除非您设置了特定的注册表键。请参阅
知识库文章如果从文件关联启动,STDIN / STDOUT重定向可能无法正常工作< a>。
它在Python README中。也许这个补丁是你要找的。 p>
This is running on Windows 7 (64 bit), Python 2.6 with Win32 Extensions for Python.
I have a simple script that just print "hello world". I can launch it with python hello.py
. In this case I can redirect the output to a file. But if I run it by just typing hello.py
on the command line and redirect the output, I get an exception.
C:> python hello.py
hello world
C:> python hello.py >output
C:> type output
hello world
C:> hello.py
hello world
C:> hello.py >output
close failed in file object destructor:
Error in sys.excepthook:
Original exception was:
I think I first get this error after upgrading to Windows 7. I remember it should work in XP. I have seen people talking about this bug python-Bugs-1012692 | Can't pipe input to a python program. But that was long time ago. And it does not mention any solution.
Have anyone experienced this? Anyone can help?
Are you asking about this?
Windows: When executing Python scripts on the command line using file type associations (i.e. starting "script.py" instead of "python script.py"), redirects may not work unless you set a specific registry key. See the Knowledge Base article STDIN/STDOUT Redirection May Not Work If Started from a File Association.
It's in the Python README. Perhaps this patch is what you're looking for.
