install_github fails when using devtools 1.12.0 on R 3.1 #1244
According to 1.12.0 description, R >= 3.0.2 is supported, however, when using devtools with R 3.1
We get the following error:
When I execute
With devtools 1.11.1 the same command works.
The text was updated successfully, but these errors were encountered:
I can confirm this issue for R 3.1.
Apparently this arises in older versions of R.
In R 3.3
The entry for libcurl is missing in older versions of R.
Furthermore, in https://cran.r-project.org/doc/manuals/r-release/NEWS.html it was announced
Hence, in file download-method.R one needs to check if the entry for "libcurl" exists at all, e.g.
any(names(capabilities()) == "libcurl")
