python - .pip 配置了需要 TLS/SSL 的位置，但是 Python 中的 ssl 模块不可用。 (Windows 10)

Question

我正在尝试安装 quandl 以在 Jupyter 笔记本中使用。 py -m pip install quandl

但是我得到以下错误，Python 中的 SSL 模块不可用。

Collecting quandl

I tried using the following, but nothing worked

```py -m pip install --trusted-host=pypi.org --trusted-host=files.pythonhosted.org --user quandl```
