问题描述
我最近使用 conda install -c r r-irkernel 安装了 Anaconda 并启用了 r 内核，我参考了：https://kyleake.medium.com/how-to-install-r-in-jupyter-with-irkernel-in-3-steps-917519326e41。
现在从 jupyter notebook 开始，当我尝试安装 tidyverse 软件包时，我收到有关 jsonlite 的错误：
Warning message:
"package 'tidyverse' was built under R version 3.6.3"
Error: package or namespace load failed for 'tidyverse' in loadNamespace(j <- i[[1L]],c(lib.loc,.libPaths()),versionCheck = vI[[j]]):
namespace 'jsonlite' 1.6 is already loaded,but >= 1.7.2 is required
Traceback:
1. library("tidyverse")
2. tryCatch({
. attr(package,"LibPath") <- which.lib.loc
. ns <- loadNamespace(package,lib.loc)
. env <- attachNamespace(ns,pos = pos,deps,exclude,include.only)
. },error = function(e) {
. P <- if (!is.null(cc <- conditionCall(e)))
. paste(" in",deparse(cc)[1L])
. else ""
. msg <- gettextf("package or namespace load failed for %s%s:\n %s",. sQuote(package),P,conditionMessage(e))
. if (logical.return)
. message(paste("Error:",msg),domain = NA)
. else stop(msg,call. = FALSE,domain = NA)
. })
3. tryCatchList(expr,classes,parentenv,handlers)
4. tryCatchOne(expr,names,handlers[[1L]])
5. value[[3L]](cond)
6. stop(msg,domain = NA)
似乎 jsonlite' 1.6 is already loaded,but >= 1.7.2 is required 是问题所在，所以当我尝试手动安装 jsonlite 时，我遇到了这个问题：
install.packages("jsonlite")
package 'jsonlite' successfully unpacked and MD5 sums checked
Warning message:
"cannot remove prior installation of package 'jsonlite'"Warning message in file.copy(savedcopy,lib,recursive = TRUE):
"problem copying C:\ProgramData\Anaconda3\Lib\R\library\00LOCK\jsonlite\libs\x64\jsonlite.dll to C:\ProgramData\Anaconda3\Lib\R\library\jsonlite\libs\x64\jsonlite.dll: Permission denied"Warning message:
"restored 'jsonlite'"
The downloaded binary packages are in
C:\Users\viny\AppData\Local\Temp\RtmpADyCWE\downloaded_packages
那么我如何在 tidyverse package 中安装 jupyter notebook？
