pip3 安装在 mac os 上失败

Question

我正在尝试在 Mac OS 10.14 上使用 pip3 版本 20.2.1 安装 ssl 模块，这给了我以下错误：

命令：pip3 安装 ssl

ERROR: Command errored out with exit status 1:

这是ssl模块本身的问题吗？

Answer 1

您不需要为 Python 3 安装 SSL 包。它是一个 built-in module。

Pypi 上的 SSL package 解释了它的用途：

The old socket.ssl() support for TLS over sockets is being superseded in Python 2.6 by a new ‘ssl’ module. This package brings that module to older Python releases, 2.3.5 and up (it may also work on older versions of 2.3, but we haven’t tried it).
