R install.packages - “curl”调用具有非零退出状态

Question

At the moment I am getting this error and don't really know how to fix it. I only get it while working on a Packrat R project.

install.packages("dplyr")

curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to cran.rstudio.com:443 Error in download.file(url, destfile, method, mode = "wb", ...): 'curl' call had nonzero exit status

I recently updated my MacOS version, as well as my R version.

I tried installing libressl/openssl via brew.

Answer 1

Here is the solution I found for this problem

1. Install or upgrade libressl, openssl, curl

2. Restart your computer (this is important)

On Mac terminal:

 brew install libressl
 brew install openssl
 brew install curl
