我通过命令安装了 httpie

sudo yum install httpie

python3 命令在 PATH 上。但是当我运行 http 命令时，它仍然使用导致错误的 python 2.7。

http命令错误

我可以确认 python 3 已安装，运行 python 命令时的 python shell

Python 3.8.5 (default, Sep  4 2020, 07:30:14)

在不知道您的操作系统及其版本的情况下，这将是一个猜测答案:)

我敢打赌你运行的是旧的 Fedora 版本或 CentOS？

如果是这种情况，HTTPie 版本非常旧（0.9.4），当时它是使用 Python 2 捆绑的。所以当你这样做时sudo yum install httpie，它将作为 Python 2 模块安装http和执行。https

评论中提出的一种解决方案是使用python3 -m pip install --upgrade httpie：它将确保您正在为 Python 3 安装 HTTPie。并且http&https可执行文件也将可用。如果你这样做，你必须首先删除你通过安装的 HTTPie 版本yum。
