I’m currently getting the following error on a Windows machine:
> devtools::install_github("hadley/readr") Error in curl::curl_fetch_disk(url, x$path, handle = handle) : Peer certificate cannot be authenticated with given CA certificates
The machine in question is sitting behind a gnarly firewall and proxy, which I suspect are the source of the problem. I also need to use
--ignore-certificate-errors when running
chromium-browser, which points to the same issue.
This seems to resolve the issue:
