Library(tidyverse) does not work

[ChristineFA]

Hi,

I am trying to install Tidyverse and I encounter the following problem

library(tidyverse)
Registered S3 methods overwritten by 'broom':
method from
augment.rowwise_df
augment.tbl_df
glance.rowwise_df
glance.tbl_df
tidy.rowwise_df
tidy.tbl_df
Error: package or namespace load failed for ‘tidyverse’:
.onLoad failed in loadNamespace() for 'broom', details:
call: loadNamespace(name)
error: there is no package called ‘backports’

When I try to install the package backports, it get the following
Warning in install.packages :
installation of package ‘backports’ had non-zero exit status

What should I do ?
I have installed R and Rstudio 10 days ago. I have the version Version 1.2.5033

Thanks in advance,

Christine

@ChristineFA

error: there is no package called ‘backports’

It means there is an issue with the backports installation.
Is it installed already ? Do you see it in the package pane in RStudio ?

In a clean R session (maybe outside Rstudio in R GUI?), try to reinstalling backports

Can you show the whole message you get when you try to install this package? You are omitting the useful parts

Here is what I get / Thanks for your help

install.packages("backports")

There is a binary version available but the source version is
later:

backports 1.1.5 1.1.6 TRUE

Do you want to install from sources the package which needs compilation? (Yes/no/cancel) y

The easiest solution would be to answer "no" when asked to install from source, that way you would get a precompiled binary that is much easier to install but a little older.
If you need the latest version then you have to install it from source, for that you need to have
xcode installed in your system

xcode-select --install

And the recommended development tools for MacOS systems

Thanks a lot. It worked.

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] :information_s…
