Cant install psych package

I am new to R-studio and I am trying to install the psych package but I get the following error:

> Error: package or namespace load failed for ‘psych’ in loadNamespace(j
> <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):  there
> is no package called ‘mnormt’

So then I tried to install the mnormt package and I get the following message:

> package ‘mnormt’ successfully unpacked and MD5 sums checked Warning in
> install.packages :   cannot remove prior installation of package
> ‘mnormt’ Warning in install.packages :   restored ‘mnormt’

But when I then try to install the psych package it keeps saying that the mnormt package was not installed.

Solution

  • Another option would be first to deinstall the defect package and afterwards run a fresh install:

    remove.packages("mnormt")

    Reinstall mnormt with:

    install.packages("mnormt")

    Then install psych package:

    install.packages("psych")

    Could have happened some files were transferred incompletely/broken after your first installation of mnormt.
