在 PyCharm 2020.1 中安装 PyQt5 + qtpy 包时出错：SSL 模块不可用

Question

After installing Qt (5.14.2) in Win10 I have created a new project in PyCharm 2020.1. From the project settings dialog, I have tried to install the PyQt5 and the qtpy packages. I get the following error:

Collecting PyQt5
Could not fetch URL https://pypi.org/simple/pyqt5/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pyqt5/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

SSL module is not available. How can I install it? Could you please help? Many thanks!

Ok, I found a solution on GitHub . .dll files have to be copied from the bin into the DLLs file.
