error: subprocess-exited-with-error

I uninstalled and reinstalled R and associated directories according to directions on another Stackoverflow post, and got the same error. I also tried installing a previous version of rpy2 and got the same error.

我按照另一篇Stackoverflow帖子上的说明卸载并重新安装了R和相关目录，但得到了相同的错误。我还尝试安装以前版本的rpy2，得到相同的错误。

If anyone has an idea how to resolve this error I'd be glad to get it.

Thanks.

如果有人知道如何解决这个错误，我将很高兴得到它。谢谢。

try

尝试

pip install wheel

or install rpy2 from github repo instead of PIP

或者从GitHub资源库安装rpy2，而不是PIP

Eventually I downloaded a zip file of rpy2 from rpy2's GitHub page, unzipped and placed it in the python project's site-packages, which enabled using the package.

最后，我从Rpy2的S GitHub页面下载了一个rpy2的压缩文件，将其解压并放入了python项目的站点包中，该包启用了该包。

I did this as some one said above ..
pip3 install wheel setuptools pip --upgrade

我是按照上面有人说的那样做的..PIP3安装轮安装工具PIP--升级

then it told me I had to install by specific use eg ..
pip3 install azure-identity
as pip install azure was deprecated .

然后它告诉我必须按特定用途安装。PIP3Install Azure-作为PIP Install Azure的身份被弃用。
