Question

我正在尝试在数据分析项目上使用pipenv，并且需要使用R中的Twitter Anomaly Detection package。

尝试pipenv install rpy2时出现错误

下面是我的代码，创建了pipenv文件夹并尝试将rpy2安装到其中。

Error:  An error occurred while installing rpy2!
Command "python setup.py egg_info" failed with error code 1 in C:\Users\amaguire\AppData\Local\Temp\pip-install-8h23my82\rpy2\

This is likely caused by a bug in rpy2. Report this to its maintainers.

我看了一下，但是通过在virtualenv或pipenv中使用rpy2的人的例子却找不到很多。

我对我是否可以使virtualenv中的rpy2知道R的居住位置感到好奇（如果那是怎么回事）。

任何非常感谢的建议，我想尝试解决这个问题也可能对其他人有用。

更新

我已经在Windows的Path变量中添加了R，现在出现如下所示的新错误。因此，希望我下载Visual C ++后能解决此问题
