Ubuntu 22.04下无法安装http及request模块求助

环境信息 #

• Ubuntu 22.04
• Python 3.10.6
• pip 22.0.2

操作与错误详情 #

执行拼写错误的安装命令：

pip install htttp

实际触发安装PyPI上的http包，过程中报错：

Collecting http

Preparing metadata (setup.py) ... error
error: subprocess-exited-with-error

× python setup.py egg_info did not run successfully.

from request import Request
ModuleNotFoundError: No module named 'request'

随后尝试安装request模块，同样失败：

pip install request

错误信息：

ERROR: Could not find a version that satisfies the requirement request (from versions: none)
ERROR: No matching distribution found for request

解决方案 #

1. 无需安装http模块：Python标准库已内置http模块，直接在代码中import http即可使用，不必通过pip安装第三方的http包——该包本身存在依赖问题，且功能完全被标准库覆盖。
2. 正确的HTTP第三方库是requests：不存在名为request的PyPI包，若需使用第三方HTTP请求工具，安装requests（注意末尾有s）：

pip install requests

3. 修正命令拼写：最初的命令pip install htttp多打了一个t，即便要安装第三方包也应为pip install http，但不建议安装该包。
