Python 通过Anaconda Navigator安装R环境后，Jupyter笔记本死机内核和Anaconda Navigator无法启动

多年来，我在我的

Macbook（OS 10.15）

上安装了一个稳定版本的Anaconda发行版

我主要用Python 3编程，所以一切都很顺利

然而，今天我按照anacondo网站上的说明安装了

R

（）

一旦我在anacondo的网站上完成安装

R

的说明，我就尝试使用打开Jupyter笔记本选项

用R软件包打开环境。

如上面链接中所述

当我这样做时，会出现以下错误：

然后，我加载一个现有的python 3笔记本，并尝试运行第一个单元格，其中包含

import numpy as np

，我得到以下错误：

RStudio

应用程序怎么可能找不到刚刚安装的内容？奇怪

有人知道发生了什么事吗？我如何解决目前存在的各种问题

存档。我猜这是卡塔利纳特有的问题。同时，如果您确保base安装了

nb\u conda\u内核

包，并且R env安装了

R-irkernel

，那么env将在从shell启动的Jupyter中显示为可用内核（如中所示）。请看，我似乎也无法让RStudio成功启动-我刚刚安装并启动了它，但获得了一个

无法通过扫描标准位置定位R二进制文件
错误还向RStudio提交了一个问题您安装了R吗？这是一个单独的安装
