尝试在Rstudio中加载包时出错

Question

我正在尝试在新的macbook pro上安装CosmoPhotoz软件包。 我在R和Rstudio中从未遇到过安装软件包的问题，​​因此我不确定如何修复此错误。

    install.packages("CosmoPhotoz", repos="http://cran.rstudio.com/", 
    dependencies=TRUE)
    library(CosmoPhotoz)

这是错误消息：

 Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) : 
 namespace ‘htmltools’ 0.2.6 is being loaded, but >= 0.3 is required
 In addition: Warning messages:
 1: replacing previous import by ‘grid::arrow’ when loading ‘ggthemes’ 
 2: replacing previous import by ‘grid::unit’ when loading ‘ggthemes’ 
 3: replacing previous import by ‘scales::alpha’ when loading ‘ggthemes’ 
 Error: package or namespace load failed for ‘CosmoPhotoz’

Answer 1

我和另一个包（sqldf）有同样的问题。

尝试使用：

install.packages(htmltools)
install.packages("CosmoPhotoz")
