ggplot2 无法加载，出现“rlang”包错误

Question

This is the error message:

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 >= 0.4.0 is required

In addition to a Warning message:

package 'ggplot2' was built under R version 3.6.1

Please help. Thanks a lot.

Answer 1

Just providing a more complete answer for people to follow.

Remove packages with

remove.packages("rlang")

That may not work as you may need to delete the package from your R library. To find where you R library is run

.libPaths()

Once you've deleted the rlang folder from there you can restart R and run

install.packages("https://cran.r-project.org/src/contrib/Archive/rlang/rlang_0.4.9.tar.gz", repo=NULL, type="source") # for specific rlang version, in this case 0.4.9. For latest version can run install.packages("rlang")
packageVersion("rlang") #to check you now have rlang version you want

Answer 2

Figured just a slight modification to the first answer worked best for me: restart R, then:

remove.packages("rlang") remove.packages("dplyr")

install.packages("rlang") install.packages("dplyr")

library(rlang) library(dplyr)

Answer 3

My solution is to restart R and then update all the packages.

update.packages(ask = FALSE)

The problem with just removing & installing rlang , and then your desired package (here ggplot2 ), you might find there are other packages you have remove and install. Best to update all and save time.

Answer 4

通过更新 R 和 Rstudio、删除“rlang”包并重新安装包、删除“ggplot2”包并重新安装包来解决问题。

Answer 5

只需更新你的 R 包，因为 ggplot2 包中有一个新的更新支持更高的 R 版本，它应该是 3.6.3 和更高版本！
