无法使用“#!/usr/bin/env python"将参数传递给 python [英] Cannot pass an argument to python with "#!/usr/bin/env python"

问题描述

我需要有一个直接可执行的 python 脚本，所以我用 #!/usr/bin/env python 启动了这个文件.但是，我还需要无缓冲的输出，所以我尝试了 #!/usr/bin/env python -u，但是失败了 python -u: no such file or directory.

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 #/usr/bin/python -u 有效，但我需要它来获取 PATH 中的 python 到支持虚拟 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.

我有什么选择?

推荐答案

最好使用环境变量来启用它.请参阅 python 文档: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

你的情况:

export PYTHONUNBUFFERED=1
script.py
