【问题描述】：

我昨天安装了 Anaconda3 (2019)、Python 3.7、Windows 10，现在我无法运行 pip install <package>。

当我运行 pip install 时，我收到以下消息：pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

当我尝试安装 ssl 模块时，我收到了相同的错误消息：

D:\>pip install D:\ssl-1.16.tar.gz

pip好像没有安装ssl模块，pip不工作时怎么安装ssl模块？

【问题讨论】：

标签： python windows pip anaconda

【解决方案1】：

运行后解决：

conda activate base

【讨论】：

【解决方案2】：

看来你的包不适合python3，它写的语法是python2的语法。你需要python3的ssl安装包

【讨论】：

在哪里可以找到它？ pip install ssl 似乎只安装了一个 ssl 包。
查看文档发现python3已经自带ssl模块，不需要安装。您可以使用 import ssl 直接导入它
