python - pip install ... 不起作用 : pip is configured with locations that require TLS/SSL, 但是 Python 中的 ssl 模块不可用

Question

我昨天安装了 Anaconda3 (2019)、Python 3.7、Windows 10，现在无法运行 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，我收到相同的错误消息:

D:\>pip install D:\ssl-1.16.tar.gz
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Processing d:\ssl-1.16.tar.gz

看起来pip不工作是因为没有安装ssl模块，但是当pip不工作时如何安装模块ssl？

运行后解决:

conda activate base
