Question

I got the following error when trying to install Hadley’s HTTR package from Github in R.

Not sure what the issue is on my end. Here is my version info on Windows 7:

$os

UPDATE: It was suggested that try to install the dev version of devtools. I got this error:

Answer 1

Did you try the dev-version of devtools?

install_github("devtools")
install_github("httr")

Had the same problem recently and this was the fix…
