Question

我正在尝试安装 library(caret)，但在 juypter 笔记本中不断收到此错误。我也试过 install.packages("ggplot2) 和 library(ggplot2) 但没有任何效果。也是 install.packages('caret', dependencies = TRUE) 但同样的错误

library(e1071)
library(caret)
library(kknn)
library(AUC)
library(MASS)


"package 'ggplot2' was built under R version 3.6.3"Error: package or namespace load failed for 'ggplot2' in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
 namespace 'rlang' 0.3.4 is already loaded, but >= 0.4.10 is required
Error: package 'ggplot2' could not be loaded
Traceback:

1. library(caret)
2. .getRequiredPackages2(pkgInfo, quietly = quietly)
3. stop(gettextf("package %s could not be loaded", sQuote(pkg)), 
 .     call. = FALSE, domain = NA)

Answer 1

操作。我以前在加载/安装包时见过这种类型的错误。密切注意错误的文本 - 特别是，这部分应该跳出来：

namespace 'rlang' 0.3.4 is already loaded, but >= 0.4.10 is required

从该行看来，您的 rlang 版本似乎需要先更新。请尝试以下操作：

install.packages('rlang')

# wait for install

install.packages('ggplot2')

无法在 juypter 笔记本中加载 ggplot2
