在 Anaconda 中安装 RStudio 时出错：`/opt/anaconda3/lib/R/bin/exec/R：加载共享库时出错：libreadline.so.6：

1

我目前正在尝试安装 Anacondas RStudio 版本。我已经通过 apt 包管理器和最新版本的 RStudio从官方CRAN 存储库安装了 R。我当前版本的 R 安装在中/usr/lib/R，路径变量设置在/usr/bin/R. 运行 Anaconda Navigator 的 RStudio 安装程序时，它会尝试在/opt/anaconda3/lib/R. 安装过程挂起，现在我无法在终端中键入 R 并打开“旧”R 版本。相反，我收到以下错误消息：

$ R
/opt/anaconda3/lib/R/bin/exec/R: error while loading shared libraries: libreadline.so.6: cannot open shared object file: No such file or directory

我尝试更新“旧”R 的路径变量，但由于在路径列表/opt/anaconda3/bin之前，usr/bin我仍然得到相同的错误：

$ export PATH=$PATH:/usr/bin/R
$ echo $PATH
/opt/anaconda3/bin:/opt/anaconda3/condabin:/home/username/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/opt/mplusdemo:/usr/bin/R

首先，我不确定这个错误意味着什么。是什么libreadline.so.6？我该如何解决这个问题？

其次，我是否需要，是否建议通过 Anaconda 安装 R？我当前的版本是从 CRAN 存储库更新的，这意味着我会在更新可用时获得更新。相反，Anacondas 版本的最新程度如何？或者，创建指向目录的符号链接是否usr/bin/R明智/opt/anaconda3/bin？

R没有找到anaconda安装

1

我正在尝试在我的 Ubuntu 系统上安装 R 包，但遇到了错误。（使用 PC 或 Mac 时我没有收到此错误）

$ R
> install.packages("leiden")

...

Error: package or namespace load failed for ‘leiden’:
 .onAttach failed in attachNamespace() for 'leiden', details:
  call: py_module_import(module, convert = convert)
  error: ModuleNotFoundError: No module named 'pandas'

我很困惑，因为我可以在我的 conda 包中看到熊猫。

$ conda list | grep pandas
pandas                    1.0.1            py37h0573a6f_0

还有哪个 python 似乎给了我我的 anaconda 安装：

/home/usrname/anaconda3/bin/python

任何建议表示赞赏。

在 Ubuntu 18.04 上安装 libmagick++-dev 的依赖问题

我正在尝试使用 install splashr，但遇到了一些依赖问题，似乎没有任何效果。我知道这与操作系统中的错误配置有关，而不是与软件包本身的问题有关，但也许你们可以提供一些指导。基本上在尝试安装 splashr 时，我得到以下日志：

它抱怨没有找到 Magick++ 并导致它所依赖的包 magick 的另一个失败安装。输出类似：

所以我进入终端安装缺少的包 libmagick++-dev，但它也没有走远，因为它一直在询问依赖项的依赖关系：

以下软件包具有未满足的依赖关系： libmagick++-dev ：依赖：libmagick++-6.q16-dev 但不会安装

依赖树还在继续：

                            libfontconfig1

由于错误，我无法安装它们中的任何一个：“......但它不会被安装”

我已经尝试多次卸载/安装 imagemagick 无济于事。

这些是有关环境变量的一些信息。

如何停止在 localhost:8787 上加载应用程序 rstudio

1

（欢迎标记建议，我不知道如何正确分类或标记我的问题）

Ubuntu 18.04。

我有一个谜。当我访问 localhost:8787 时，我被带到 rstudio 登录屏幕：

我不知道在 localhost:8787 托管 rstudio 应用程序的进程是什么。几周前，我确实为通过 localhost:8787 访问的 rstudio 运行了一个 docker 容器。但是，该容器已被停止、删除，事实上，我已经删除了所有 docker 镜像：

（这里没有容器）

docker container ls
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

甚至没有要运行的图像：

docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

在搜索“如何判断本地主机上托管的进程”后，我发现了一篇帖子。我不确定在这里使用什么搜索词。

经过一番搜索，我在终端中运行了这个命令：

netstat -aon | grep 8787

哪个返回了这个：

从 R 中的闪亮应用 runApp() 时连接到 firefox 失败

我正在做闪亮的教程，就像在https://shiny.rstudio.com/tutorial/written-tutorial/lesson1/上解释的那样

在某个时候，我必须运行示例应用程序。示例应用程序存储在文件夹/usr/local/lib/R/site-library/shiny/examples/01_hello 中，我想在终端中运行它。所以我输入

sudo -i R  # entering my password so that R is being started
library(shiny)
runApp("/usr/local/lib/R/site-library/shiny/examples/01_hello")

但它不起作用。

我的控制台给了我以下错误信息：

此处不支持在常规用户会话中以 root 身份运行 Firefox。（$XAUTHORITY 是 /run/user/1000/gdm/Xauthority，归基数所有。）我发现了 firefox 问题，但与 R 无关...

我的目标是在输入runApp()Firefox 后分别打开一个新选项卡并显示闪亮的应用程序，以便我可以与之交互。

另外我不得不说，我是 ubuntu 的新手——所以在回答我的问题时请记住这一点。提前谢谢了！

有时命令在升级到 R 4.0 和 Ubuntu 20.04 后不会终止

1

几天前我已经将 R（从 3.6 升级到 4.0）和 RStudio（从 1.1 升级到 1.2.5），昨天将 Ubuntu 从 18.04 升级到 20.04。

从那时起，R有时在执行某些命令时永远不会终止：（ivreg来自 package AER）、summary（来自 logit 回归）和logitmfx（来自 package mfx）。有时这些命令运行良好，但大多数时候我必须终止进程（killall rstudio），因为 R 不会终止执行，即使按下 RStudio 中的红色停止按钮也是如此。

当我尝试example('AER')时，它工作得很好。然后我重新安装了包AER。In readLines(file, skipNul = TRUE) : cannot open compressed file '/usr/lib/R/site-library/[package]/DESCRIPTION', probable reason 'No such file or directory'它抛出了 10 个where [package]is abind, colorspace, ...类型的警告dichromat（但不是AER）。

此后example('AER')引发警告：no help found for ‘AER’.

我已经删除并重新安装了 R 4.0：它没有帮助。此外，apt purge r-base* r-recommended r-cran-*抛出警告：dpkg: warning: while removing r-base-core, directory '/usr/lib/R/site-library' not empty so not removed. 此外，还有一堆Package [package] is not installed, so not removed，包括 for [package]equal tor-cran-abind和上面列出的另一个（这purge也返回了一堆Note, selecting [package] for glob 'r-cran-*'）。

我没有尝试在没有 RStudio 的情况下使用 R。在升级到 Ubuntu 20.04 期间，我可能正在使用 RStudio。另外，我不记得这个问题是在我升级 R 和 RStudio（这是我最好的猜测）之后还是在我升级 Ubuntu 之后（一两天后）开始的。

我希望有人能帮帮忙。

在 Ubuntu 18.04 中安装 R 版本 3.6.3 - “make”问题

我已经卸载了旧的 R 版本，我正在尝试重新安装（我的操作系统是 Ubuntu 18.04）。我正在使用这些命令：

cd Downloads
tar -zxvf R-3.6.3.tar.gz
cd R-3.6.3
./configure --enable-R-shlib

之后，我尝试使用这些：

make
sudo make install

但是，当我键入 make 时，我收到以下消息：

make: *** No target indicated and no make file found. Stop.

我该如何处理？

无法在 GNU R 和 Ubuntu 20.04 中使用 solve() 函数

3

昨天我将我的 Kubuntu 19.10 机器更新到了 20.04，到目前为止我对升级感到满意。但是我发现更新后我的 GNU R 安装存在一个严重问题，并寻求您的帮助。

问题是，我不能在 GNU R 中使用 solve() 函数。具体来说，每当我尝试使用上述函数反转矩阵时，控制台就会挂起。下面我详细解释一下这种情况。

考虑代码

D = matrix(
data = c(1, 2, 3, 4),
nrow = 2,
ncol = 2,
byrow = TRUE
)
solve(D)

如果我在 R 中启动从终端调用的代码，比如 Konsole，会话将冻结。
- 我知道系统冻结的确切时间是我执行solve()函数的时候。
- 根据 htop，当这种情况发生时，我的一个 CPU 内核被 100% 使用。
如果我在 RStudio 的控制台中启动相同的代码，代码会按预期工作。但是，如果我使用 RStudio 中的终端调用它，会话就会挂起。
使用 --vanilla 启动 R 并不能解决问题。
重新启动 PC，使用我的外部显卡，在 apt 中重新安装 r-base-core 包，并尝试使用不同的终端仿真器都没有帮助。
从 R 中solve( ) 函数的文档可以看出，solve(A, B) 实际上有两个参数：A 是矩阵，B 是向量或矩阵。如果 B 是向量，则求解线性系统 Ax = B。如果 B 是矩阵，则求解 AX = B 并返回 X。如果在第二个参数中没有给出任何内容，它会自动将适当大小的单位矩阵假定为 B。求解线性系统的第一个函数起作用。但是，如果我将矩阵指定为第二个参数，则会发生同样的问题。
使用 qr.solve(A) 的 QR 分解仍然可以很好地工作。

以下是我的问题：

有没有人和我一样的问题？
我还寻求有关如何解决此问题的建议。

供您参考，我使用的是从默认 apt 存储库安装的 R 版本 3.6.3。

感谢您的阅读，并保持安全！

ps 我在这个 Ubuntu 社区提出这个问题，因为我认为这是一个特定于 Ubuntu（或者实际上是我的特定机器的问题）的问题，因为我在 R 相关网站中没有找到相关信息或错误报告。

从可执行的 bash 脚本文件执行 N0rbert 的代码，会话在solve(D) 处挂起。
