I run this on Arch Linux, python defaults to python 3 and the project is not python 3 but Im not sure if thats it.
我在 Arch Linux 上运行它，python 默认为 python 3，项目不是 python 3，但我不确定是否是这样。
Thanks.
谢谢。

file is not defined in Python3, which you are using apparently. The package you're instaling is not suitable for Python 3, instead, you should install Python 2.7 and try again.
文件未在 Python3 中定义，您显然正在使用它。您正在安装的包不适用于 Python 3，相反，您应该安装 Python 2.7 并重试。
See: http://docs.python.org/release/3.0/whatsnew/3.0.html#builtins

It seems that your project is written in Python < 3. This is because the file()builtin function is removed in Python 3. Try using Python 2to3 toolor edit the erroneous file yourself.
您的项目似乎是用 Python < 3 编写的。这是因为Python 3 中删除了file()内置函数。尝试使用 Python 2to3 工具或自己编辑错误文件。
EDIT: BTW, the project pageclearly mentions that
编辑：顺便说一句，项目页面清楚地提到
Gunicorn requires Python 2.x >= 2.5. Python 3.x support is planned.
Gunicorn 需要 Python 2.x >= 2.5。计划支持 Python 3.x。

Use open()instead; see Built-in Functions - open().
使用open()代替; 请参阅内置函数 - open()。
