Os X Could Not Be Installed No Packages

Posted on by

Hi,

I'm new to R, because we're using it at Uni, and I'm having problems installing Rcdmr.

I've downloaded R 3.5.1. as well as XQuarts and the other tools CRAN told me to download, and I've even followed the step-by-step instructions (https://socialsciences.mcmaster.ca/jfox/Misc/Rcmdr/installation-notes.html) written by John Fox himself, but I'm getting error an error message I don't understand:

OS X No Packages were eligible for install repaired “No packages were eligible for install” is a message that appears when attempting to install OS X El Capitan on older macs. MacBooks are a very popular purchase in Melbourne and around Australia so it is important to understand the reasoning behind why this message appears. May 31, 2021 Another method to fix OS X could not be installed on your computer is to update your macOS in Safe Mode. In Safe Mode, your Mac can run under a pure environment without the interruption of hardware failure and startup items. It can also solve some issues on your Mac. How to enter Safe Mode on Mac?

What does it mean?

I also tried installing the library after the step described above, but then I'm getting this message instead:

library(Rcmdr)
Loading required package: splines
Loading required package: RcmdrMisc
Loading required package: car
Loading required package: carData
Error: package or namespace load failed for ‘car’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘data.table’
Error: package ‘car’ could not be loaded

As far as I can surmise, in the first step, Rcmdr is put in some weird folder which then creates the error 'package 'car' could not be loaded'.

All of this is essentially me saying 'HELP'. And before you suggest I go to my professor, I've already done that, and he couldn't help me either. Just made comments about how Mac computers are stupid, essentially. So I need your help, Internet!

Sincerely,
A complete R newbie who just wants to use it for his statistics class

How Do You Fix No Packages Were Eligible For Install

  • Install Homebrew


    Paste that in a macOS Terminal or Linux shell prompt.

    The script explains what it will do and then pauses before it does it. Read about other installation options.

  • What Does Homebrew Do?


    Homebrew installs the stuff you need that Apple (or your Linux system) didn’t.

  • Homebrew installs packages to their own directory and then symlinks their files into /usr/local.

  • Homebrew won’t install files outside its prefix and you can place a Homebrew installation wherever you like.

  • It’s all Git and Ruby underneath, so hack away with the knowledge that you can easily revert your modifications and merge upstream updates. Beck hopelessness scale questionnaire.

  • Homebrew complements macOS (or your Linux system). Install your RubyGems with gem and their dependencies with brew.

  • “To install, drag this icon…” no more. Homebrew Cask installs macOS apps, fonts and plugins and other non-open source software.

  • Donate to Homebrew
