不能传递参数与＆QUOT到Python;＃！的/ usr /斌/包膜蟒蛇＆QUOT; [英] Cannot pass an argument to python with "#!/usr/bin/env python"

问题描述

我需要有一个直接执行的python脚本，所以我就开始用＃文件！在/ usr /斌/包膜蟒蛇。不过，我也需要缓冲的输出，所以我尝试＃在/ usr /斌/包膜蟒蛇-u ，但失败蟒蛇-u！没有这样的文件或目录。

I needed to have a directly executable python script, so i started the file with #!/usr/bin/env python. However, I also need unbuffered output, so i tried #!/usr/bin/env python -u, but that fails with python -u: no such file or directory.

我发现＃的/ usr / bin中/ Python的-u 的作品，但我需要它来获得蟒蛇在 PATH 来支持虚拟 ENV 环境。

I found out that #/usr/bin/python -u works, but I need it to get the python in PATH to support virtual env environments.

我有哪些选择？

推荐答案

这是更好地利用环境变量来启用它。见蟒蛇DOC： http://docs.python.org/2/using/cmdline.html

It is better to use environment variable to enable this. See python doc : http://docs.python.org/2/using/cmdline.html

对于你的情况：

export PYTHONUNBUFFERED=1
script.py
