Packages download to temp folder and are unable to load

[dsm.shen]

I seem to be able to download the devtool package just fine, though it downloads to a temp folder even though I've specified the library directory. Though, when I try to load it, it tells me that "usethis" is required, so I download "usethis," and when I go to load it, I get Error: package or namespace load failed for ‘usethis’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object

This is what I'm running:

install.packages("devtools", lib = "/Library/Frameworks/R.framework/Versions/3.6/Resources/library", repos = "http://cran.us.r-project.org")
library(devtools)
install.packages("usethis", lib = "/Library/Frameworks/R.framework/Versions/3.6/Resources/library")
library(usethis)

The output:

The binaries get downloaded to a temp folder not the package itself.

I download "usethis," and when I go to load it, I get Error: package or namespace load failed for ‘usethis’ in dyn.load(file, DLLpath = DLLpath, ...):

Try reinstalling fs package

Also, please do not post screenshots here, post formatted code instead, here is how to do it.

FAQ: How to format your code

Formatting Code: the Basics All code or console output you include in your posts should be formatted properly. Luckily, this is very easy to do! Just use the code formatting button at the top of the post editing box: [image] Select some code Click the </> button! The code formatting button automatically adds special Markdown formatting symbols to whatever you selected. If you check the preview pane to the right of your post, you'll see that the forum software now outputs nicely formatted code . [04] The code formatting button is pretty smart! It can tell the difference between snippets of code that are part of a sentence and blocks of code that stand alone. …

Thanks for the feedback andresrcs, I edited the original post with formatted code.

Also, I tried removing and reinstalling the fs package with the same results when I try to load. Do you have any other suggestions?
