安装包不起作用：权限被拒绝

Question

我正在努力安装“psych”包。

我开始使用命令install.packages("psych")。下载开始，结果如下：

Installing package into ‘C:/Users/Username/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
also installing the dependency ‘mnormt’

trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.5/mnormt_1.5-5.zip'
Content type 'application/zip' length 373388 bytes (364 KB)
downloaded 364 KB

trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.5/psych_1.8.4.zip'
Content type 'application/zip' length 5741178 bytes (5.5 MB)
downloaded 5.5 MB

Error in install.packages : cannot open file 'C:/Users/Username/Documents/R/win-library/3.5/file41147bc27f90/mnormt/CITATION': Permission denied

之后我搜索了结果。我禁用了我的防火墙。我还以管理员权限启动了 RStudio。一个建议是在 R（不是 R Studio）中安装包

在那里我尝试再次安装它。结果如下：

Installing package into ‘C:/Users/Username/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)

also installing the dependency ‘mnormt’

您还有其他解决方法的想法吗？解压程序有问题吗？

Answer 1

你可以.libPaths()吗？

也许.libPaths() 没有映射正确的位置（如果您不是管理员）

试试.libPaths(.libPaths()[2])，然后再试试install.packages("psych")。
