python - 尝试在 linux 中安装 fabric 时出现 fabric(python 模块)错误

Question

我是 fabric 工具的新手，我已经在使用 python 了。 当我尝试通过 easy_install 安装 fabric 时，出现以下语法错误。

我没有更改我的脚本中的任何内容，我正在通过结构代码下载并尝试通过简单安装进行安装:

请检查以下错误，并给出我将如何进一步处理的建议。

Fabric 需要 Python 2.5 或更高版本，而您使用的是 2.4。参见 official docs

We are not planning on supporting Python 2.4 given its age and the number of useful tools in Python 2.5 such as context managers and new modules. That said, the actual amount of 2.5-specific functionality is not prohibitively large, and we would link to – but not support – a third-party 2.4-compatible fork. (No such fork exists at this time, to our knowledge.)
