【问题描述】：
由于无法导入 ssl，我无法调试代码或运行 Python 控制台。我在使用我创建的两个 Anaconda 虚拟环境时会出现这种情况。
例如，当我尝试调试使用 boto3 的 Python 代码时，我看到以下错误：
C:\home\miniconda\envs\scw\python.exe "C:\Program Files\JetBrains\PyCharm Community Edition 2018.3.4\helpers\pydev\pydevd.py" --multiproc --qt-support=auto --client 127.0.0.1 --port 57111 --file C:/home/git/onvif_interact/onvif_interact/notifications.py --config C:\home\data\pullpoint\camera_desk.ini

当我尝试运行 Python 控制台时，我收到了类似的错误：

可能相关的是我在 PyCharm 中创建了一个新的虚拟环境，当我尝试更新 pip 模块时发生以下与 SSL 相关的错误：
Collecting pip==19.0.1
Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

顺便说一句，我已经用新安装的 Miniconda 替换了我的 Miniconda 安装，但我继续收到上述错误。我从 python.org 安装了 Python 3.7 并基于它创建了一个虚拟环境，但我没有收到上述错误，所以我的假设是这在某种程度上与 Miniconda 环境有关，尽管该环境直到今天都运行良好。接下来我将尝试安装一个完整的 Anaconda 环境，看看是否有什么不同。
