R语言部分包之前能加载，现在加载不了

求大神解决。

例如

>library(readxl)

错误: package or namespace load failed for ‘readxl’ in dyn.load(file, DLLpath = DLLpath, ...):  无法载入共享目标对象‘/Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so’：:   dlopen(/Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so, 6): Symbol not found: _EXTPTR_PTR   Referenced from: /Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so   Expected in: /Library/Frameworks/R.framework/Resources/lib/libR.dylib  in /Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so

还有

> library(reshape2)

错误: package or namespace load failed for ‘reshape2’ in dyn.load(file, DLLpath = DLLpath, ...):  无法载入共享目标对象‘/Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so’：:   dlopen(/Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so, 6): Symbol not found: _EXTPTR_PTR   Referenced from: /Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so   Expected in: /Library/Frameworks/R.framework/Resources/lib/libR.dylib  in /Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so 此外: Warning message: 程辑包‘reshape2’是用R版本4.0.2 来建造的

问题的出现是在运行了一下代码，

install.packages("BiocManager")

BiocManager::install("ggtree")

中间出现2次提示（具体记录找不到了），我都选择了all/yes, 后面发现没有安装上去，然后出现了以上问题。

在R 终端中运行以下行 

 

  1. update.packages(ask=FALSE,

  2. checkBuilt=TRUE,

  3. repos="https://cloud.r-project.org")

然后

 

  1. install.packages(c("Rcpp", "caret", "forecast", "ggplot2", "quadprog"),

  2. dependencies=TRUE,

  3. repos="https://cloud.r-project.org")

你好，我按照代码在terminal中运行了，提示有这个问题

(base) liuyawendeMacBook-Air:Adjust1 liuyawen$ update.packages(ask=FALSE,checkBuilt=TRUE,repos="https://cloud.r-project.org")
bash: syntax error near unexpected token `ask=FALSE,checkBuilt=TRUE,repos="https://cloud.r-project.org"'

你在解决解决
