r - 如何正确安装和加载dplyr？

Question

我目前正在通过Spiro包练习R编程。而且我在其中一门类(class)的安装步骤中遇到了以下错误。

| This lesson requires the ‘dplyr’ package. Would you like me to install it for
| you now?

1: Yes
2: No

Selection: 1

| Trying to install package ‘dplyr’ now...
package ‘dplyr’ successfully unpacked and MD5 sums checked

| Could not install package ‘dplyr’!

  |                                                                            
  |                                                                      |   0%Error in seq.default(0, 1, length.out = nrow(e$les)) : 
  argument 'length.out' must be of length 1

| Leaving swirl now. Type swirl() to resume.

即使我尝试手动安装它并成功完成，由于以下错误我也无法加载。

> library(dplyr)
Error: package or namespace load failed for ‘dplyr’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
 namespace ‘rlang’ 0.4.5 is already loaded, but >= 0.4.6 is required 

我试图删除，重新安装和更新软件包。似乎没有任何作用。请帮忙

Answer 1

要么

install.packages("dplyr", dependencies = TRUE)

还是先回去做

install.pacakges("rlang")

然后安装 dplyr。

欢迎来到Package Hell。这是您的类卓琴。昨晚我必须安装4个级别的软件包，然后才能加载所有 tidyverse。这很乏味但可行。
