安装 python 3 后，httpie 仍然使用 python 2.7

Question

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 python 2.7 导致错误。

http 命令错误

我可以确认 python 3 已安装，python shell 当我运行 python 命令

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

Answer 1

在不知道您的 OS 及其版本的情况下，这将是一个猜测答案:)

我打赌你是运行旧的 Fedora 版本或 CentOS?

如果是这样，HTTPie 版本很旧 (0.9.4)，当时它是使用 Python 2 捆绑的。所以当您执行 sudo yum install httpie 时，它将安装 http 和 https 可执行为 Python 2 个模块。

评论中提出的一个解决方案是使用 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。如果这样做，您必须先删除通过 yum.

安装的 HTTPie 版本

安装 python 3 后，httpie 仍然使用 python 2.7

httpie still use python 2.7 when python 3 is installed

python

httpie
