I\'m trying to install devtools in a PowerPC with a R version 3.1.1 but failed at the end because the curl library:
...
** testing if installed package can be lo
For Curl use:
apt-get -y build-dep libcurl4-gnutls-dev
apt-get -y install libcurl4-gnutls-dev
And you should update the R version to R-3.1.2
wget http://cran.r-project.org/src/base/R-3/R-3.1.2.tar.gz
I m using Ubuntu 16.04 and this is how I solved this issue:
aptitude install libssl-dev
then aptitude packg manage will allow you to choose the right version which is required for installation of devtools. Repeat the same for
aptitude libcurl4-gnutls-dev
aptitude libxml2-dev
Finally, install this libgit2 lib
devtools::install_github('ropensci/git2r')
devtools::load_all()
R CMD INSTALL git2r
I could not solve it with apt-get packg manager. Thats all :) !
This error was happening when I was using 3.0.2. I updated the R, now It is fine. I also spent the one day to find the solution. I tried the all the solution. But, no effect. I updated the R using this solution. Now, devtools package is working.
The same problem happened to me when I was trying to install "devtools" package on a new machine with Ubuntu 16.04 system.
I tried many answers including the adopted one above, but I still couldn't solve the problem until I noticed another warning information "(as ‘lib’ is unspecified)". Then I realized that I was running R as a normal user while the R base is installed by root. It means the package "devtools" couldn't be installed into the default R library folder and possibly couldn't use some dependent packages. Then the solution became very easy: run R as root user and then install "devtools".
Following the instructions of Dean Attali (https://www.digitalocean.com/community/tutorials/how-to-set-up-r-on-ubuntu-14-04), I summarize the steps below. Just run them in a terminal.
$ sudo apt-get -y install libcurl4-gnutls-dev libxml2-dev libssl-dev
$ sudo su
$ R
> install.packages('devtools', repos='http://cran.rstudio.com/')
That's it. Since the package is installed by root, it can be used by all users of the system.
