Error installing ggplot2 in RStudio - MacOS - r

Question

I'd like to express my thanks in advance for your help. I have been attempting to install the package "ggplot2" for two weeks now in RStudio, and cannot figure out my non-zero exit status errors. I have posted the resulting error code at the end of this message. I have successfully installed some packages, but have failed to install ggplot2 and plotly. I have an assignment due using these packages tonight and would greatly appreciate any insight you can give.
> install.packages("ggplot2", dependencies = TRUE)
also installing the dependencies ‘cli’, ‘rlang’, ‘lifecycle’, ‘scales’
There are binary versions available but the source versions are later:
binary source needs_compilation
cli 3.2.0 3.4.1 TRUE
rlang 1.0.2 1.0.6 TRUE
lifecycle 1.0.1 1.0.3 FALSE
scales 1.1.1 1.2.1 FALSE
ggplot2 3.3.5 3.3.6 FALSE
Do you want to install from sources the packages which need compilation? (Yes/no/cancel) Yes
