Readr loading error HELP

[asafi17]

Hi - hoping someone can help with an error that I'm getting when I try to load the 'readr' package. The error message I'm getting looks like this:

library('readr')
Error: package or namespace load failed for ‘readr’:
.onLoad failed in loadNamespace() for 'readr', details:
call: loadNamespace(name)
error: object 'pkgInfo' not found
In addition: Warning messages:
1: package ‘readr’ was built under R version 4.0.5
2: In loadNamespace(name) : package ‘tzdb’ has no 'package.rds' in Meta/

Have you tried reinstalling it? install.packages("readr")

[asafi17]

hi, yep same problem

Error: package or namespace load failed for ‘readr’:
 .onLoad failed in loadNamespace() for 'readr', details:
  call: loadNamespace(name)
  error: object 'pkgInfo' not found
In addition: Warning messages:
1: package ‘readr’ was built under R version 4.0.5 
2: In loadNamespace(name) : package ‘tzdb’ has no 'package.rds' in Meta/

What version of R are you using?

[asafi17]

I am using version 4.0.2

It also looks like you may have a broken version of tzdb. You could also try install.packages(“tzdb”) then restart R

[asafi17]

yeah tried this too, but no luck

[davis]

So what does library(tzdb) do in a completely new R session?

[asafi17]

> library(tzdb)
Error in library(tzdb) : ‘tzdb’ is not a valid installed package

[davis]

Ok, I think you should try:

1. remove.packages("tzdb")
2. Restart R
3. Call install.packages("tzdb") and post the entire output of that for us to look at

Okay you seem to have a broken version of tzdb installed somehow that R can't delete. Can you try:

1. Close out of R / RStudio entirely
2. Go to C:\Users\\OneDrive - WBG\Documents\R\win-library\4.0 and delete the entire tzdb folder
3. Open RStudio
4. install.packages("tzdb")

[davis]

There are also reports here that OneDrive locks files incorrectly. So your problem is likely that your R package library is on your OneDrive, which is causing issues like this installing and removing odbc R package on Windows 10 - Stack Overflow

[asafi17]

so I tried to delete the tzdb folder directly, but am unable to. The folder has been "syncing" in the one drive for a suspicious amount of time

[davis]

Maybe you can force one drive to stop syncing temporarily, and delete it that way?

In general, if you are able to do so then I would recommend moving your R package library off of OneDrive and onto your computer's local storage, I think this will save you a lot of headache in the end if you use R a lot.

Within the last 24 hours (but not before) I also received errors relating to readr , for me it was crashing deployment of my Shiny app. Specifically it was at this step

building: Building package: readr

which did not occur before. I uninstall/re-installed it but no luck. The only success I had was to uninstall the version of R I was using, delete the old readr library (and I also removed several others) - then upgraded to R 4.1.2 and do a fresh install.packages("readr")

[davis]

A new version of readr just went to CRAN and the binaries haven't all been built yet, so your computer was trying to install it from source (which is sometimes harder / more prone to issues). It is possible the 4.1.2 binary was built, but the one for your older version of R wasn't, so that may be why updating helped. In a few days CRAN should have all of the binaries built so this won't be an issue anymore.
