在conda环境（运行Python 3.8）中安装rpy2 3.3.2的最佳方法是什么？

我尝试在conda环境中的Mac上安装最新版本的rpy2，方法是进入conda Navigator中的环境，单击我的环境，然后搜索rpy2。但是，此最新版本未显示

我还尝试通过以下方式通过终端进行安装：

pip install rpy2

这将生成以下错误消息：

Could not fetch URL https://pypi.python.org/simple/rpy2/: There was a problem confirming  the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:661) - skipping
Could not find a version that satisfies the requirement rpy2 (from versions: )
No matching distribution found for rpy2

我还尝试：

conda install rpy2==3.3.2 

但出现以下错误：

Collecting package metadata (repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

安装此软件包并使其在anaconda环境中可用的最佳方法是什么？

如果您使用的是Windows，您可能需要查看rpy2的GitHub并尝试从源代码安装（最新版本不支持Windows，但最近有人提供了修复程序，使其具有潜在可用性）。或者只使用旧的rpy2版本。
