安装 autopy 时出现“SyntaxError: invalid syntax”

如何解决安装 autopy 时出现“SyntaxError: invalid syntax”

我需要运行需要 autopy 的代码（对于 python 2.7）

Python 2.7

setuptools-rust 0.11.4

自动 4.0.0

C:\pip install autopy
DEPRECATION: Python 2.7 will reach the end of its life on January 1st,2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip,can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

为什么我会看到这个错误？我是python的新手

解决方法

安装代码使用格式字符串（f-strings），仅 Python 3.6+ 支持。由于您使用的是 Python 2.7，它无法识别这一点并引发语法错误。要解决此问题，您至少需要升级到 Python 3.6 或更高版本。
