pip 在 python 3.5 中安裝 json2html 不起作用

Question

我安裝了 python 3.5 和 2.7，我只使用 python 3.4。

嘗試安裝 pip install json2html 時，會生成錯誤：

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: json2html in /home/ubuntu/.local/lib/python2.7/site-packages (1.3.0)

如何在 python 3 上安裝 json2html？

您是否嘗試過通過指定 python 版本來安裝它？ python3.4 -m pip install SomePackage見這個。
