Problems installing the devtools package

Question

I wish to use the devtools package. I've run the following commands:

> install.packages("devtools", dependencies = TRUE)
....
> library(devtools)
Error in library(devtools) : there is no package called ‘devtools’

What am I doing wrong?

Edit: Here are the results of re-running the install.packages command after restarting the session.

Very hard to say based on this information. did the installation appear to go successfully?? — Ben Bolker, Jan 04 '14 at 16:16
@BenBolker: I can't tell anymore. I was silly enough to log out of the session without noticing whether the installation was successful. I logged out thinking R needs to "restart" in order to pick up the newly installed package. Unfortunately, it didn't work as expected... Is there anything I can do about it now? — Evan Aad, Jan 04 '14 at 16:20
@damienfrancois: I've updated my original post with the relevant output. — Evan Aad, Jan 04 '14 at 16:38
Try installing `curl-dev` or `curl-devel` with your package manager, or search for `libcurl` — damienfrancois, Jan 04 '14 at 16:57

As per damienfrancois's suggestion, I installed libcurl4-gnutls-dev and the problem was solved.

I have tried your methods in Ubuntu and the instructions seem work well and installation of devtools seems also succeed. but when I try to use` library(devtools)` to load the library but I only get those message `Error in library(devtools) : there is no package called ‘devtools’` – sikisis Jul 24 '15 at 09:22

I don't think you need the build dependencies (`build-dep`) for `libcurl4-gnutls-dev`, since you're not going to build it yourself. Just installing the package should work fine. – Gerhard Burger Nov 06 '15 at 10:28
Is there any chance to get it working on Windows too? – Marian Klühspies Nov 25 '15 at 23:38
The build deps will pull libssl-dev which seems to be needed by git2r. – Lars Schillingmann Feb 26 '16 at 20:40

None of the above answers worked for me on Ubuntu 18.04.3 LTS using R version 3.6.1

Best solution to solve this. I was searching the same problem. I spent 1 day and then I got solution. Now, It is well.

Check your R version in bash terminal if you are on Ubuntu or Linux.

R --version

then use these commands

sudo apt-get update 
sudo apt-get upgrade

Now check the new version of R. Use this command

sudo apt-cache showpkg r-base

Now update the R only.

sudo apt-get install r-base

Now R will be updated and the error will be removed. Make sure to cd the library path where you want to install the new package. This way in bash terminal. Try to create the R directory at home folder or it will be at the default. Locate this location for package ~/R/lib/ .

R
.libPaths("~/R/lib")
install.packages("devtools")

OR

install.packages("devtools", lib="~/R/lib")

The downloaded source packages are in

look at bold libraries which are missing libssl-dev libxml2-dev

just you need to install these libraries in ubuntu terminal or

whatever operating system you are using you will find relative errors w r t operating system see errors in details.. R-studio mentioned relative library package name against operating system

for ubuntu i did this

sudo apt-get install libssl-dev

**sudo apt-get install libxml2-dev **

sudo apt-get install libcurl4-openssl-dev

On Ubuntu (20.04 focal), I needed to run this first:

apt-get update
apt-get install build-essential libcurl4-gnutls-dev libxml2-dev libssl-dev libfontconfig1-dev libharfbuzz-dev libfribidi-dev libfreetype6-dev libpng-dev libtiff5-dev libjpeg-dev -y

Then installation of devtools worked.

This might seem like overkill but all were necessary for me (well, I'm not totally sure if build-essential is necessary, but it didn't hurt - I got that from here).

The way I figured which system libraries to install was by looking at the error messages carefully whenever install.packages("devtools") failed, because often the error message would tell you which system library to install, it's just that it was buried in the middle of the error message so it was hard to spot.

score 1 · Answer 17 · edited Jan 28 '23 at 02:09

My personal experience:

I updated both R and RStudio. Then I installed devtools. As it gave me the same issues, I started installing the dependencies as appeared in the line:

`ERROR: dependencies ‘httr’, ‘RCurl’ are not available for package ‘devtools’ ` one by one.

When you install them (for example the xml2 as in my case),

install.packages("xmls2")

It says:

Configuration failed because libxml-2.0 was not found. Try installing:
 * deb: libxml2-dev (Debian, Ubuntu, etc)
 * rpm: libxml2-devel (Fedora, CentOS, RHEL)
 * csw: libxml2_dev (Solaris)

The answer is in the response. Here I went to the command prompt and used:

sudo apt install libxml2-dev

Then I reused the command:

install.packages("xmls2")

I used a similar procedure for all other packages. Then finally,

install.packages("devtools"))

Sometimes one package may block the installation of many other packages. So please start installation from the first dependency on the list.
