无法在 PyCharm 上安装 PySimpleGUI

Question

我正在尝试在我的 Mac (MacOS 13.0.1) 上的 PyCharm 上安装 PySimpleGUI。两种推荐的安装方式都不起作用：

当我尝试通过设置 > Python 解释器 > + > PySimpleGUI > 安装包进行安装时

我收到这条消息：

Error occurred when installing package 'PySimpleGUI'.

然后建议尝试通过在终端中运行 pip 命令来安装。当我在终端中运行 pip 和 pip3 命令时，我收到以下消息：

WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:992)'))': /simple/pysimplegui/

如果有人能够确定问题，请告诉我

我试过观看 youtube 教程并阅读此处的帖子以获得此问题的答案，但我找不到任何专门为我回答此问题的内容。
