Devtools: Getting error messages when installing RStudio addins - Error in curl::curl_fetch_memory(url, handle = handle) : Problem with the SSL CA cert (path? access rights?)

[darny]

Hi. Darny here - an RStudio newbie.

It was recommended that I post my question here.

My current versions are: RStudio 0.99.878 & R 3.2.3 installed in a Windows 7 Professional – 64 bit laptop.

I have the latest versions of htmltools, shiny, and miniUI.

I followed the installation instructions from https://github.com/rstudio/addinexamples and http://rstudio.github.io/rstudioaddins/.

I tried using the Install button from the Packages Pane in RStudio, to no avail. (I used the keyword addin)

I entered this in the console and gave me error messages:

> if (!requireNamespace(“devtools”, quietly = TRUE))
+ install.packages(“devtools”)

How can I install the addins package successfully?

Thanks in advance.

Please restart R then install.packages(c("curl", "httr")) then try again.

[darny]

It worked ! Very much appreciated, @hadley !

I was having the same problem using install_from_swirl(...) in the swirl package that's used in the Coursera Data Science Specialization. Thanks for your help and inspiration, Dr. Wickham!

Hi,

R version 3.3.3 (2017-03-06)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 7 x64 (build 7601) Service Pack 1

when running these commands:

install.packages(c("curl", "httr"))
sc <- spark_connect(master = "my_cloud_url", method = "livy")

Following error comes:

Error in curl::curl_fetch_memory(url, handle = handle) :
Couldn't connect to server

I'm still getting the "SSL CA cert (path? access rights?)" after updating "curl" and "httr".
