尝试从终端安装 pip 时出错答案

【问题标题】：Errors while trying to install pip from terminal尝试从终端安装 pip 时出错
【发布时间】：2018-06-18 14:22:50
【问题描述】：

我正在尝试通过 bash 脚本/终端安装 pip3。我正在使用以下命令：

curl -O https://bootstrap.pypa.io/get-pip.py
/usr/local/bin/python3.6 get-pip.py

当我运行这两个命令时，我得到了一些我不理解的奇怪错误。有人可以解释这些错误的含义以及如何修复它们（或者让我知道是否有比 brew 更好的安装 pip3 的方法）？

【问题讨论】：

我认为您需要根据这一行在python中安装SSL模块：''pip配置了需要TLS / SSL的位置，但是Python中的ssl模块不可用。''跨度>
是的，但我不需要 pip 来安装模块吗？
我应该只使用easy_install 来获得我想要的pip 的适当版本吗？然后去那里用pip 安装东西？
我觉得你需要安装openssl这样的系统模块，我不知道在MacOS上怎么做
我认为是第一个命令产生的错误，在https中不带s试试

【解决方案1】：

此错误消息的原因是您的系统缺少 SSL 模块，您无法对HTTPS URL 执行任何请求，请尝试不使用“s”http 而不是 https

或最好的，安装 OpenSSL 可能使用 brew install openssl 查看官方文档以获取更多信息，祝你好运！
