Problems installing the devtools package

问题:

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.

> install.packages("devtools", dependencies = TRUE)

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

EDIT (@dardisco)

In your shell:

apt-get -y build-dep libcurl4-gnutls-dev
apt-get -y install libcurl4-gnutls-dev

回答2:

If you are using Ubuntu/Linux:

sudo apt-get install libcurl4-openssl-dev libssl-dev

回答3:

In case if you are using CentOS:

Try:

sudo yum -y install libcurl libcurl-devel

回答4:

For ubuntu users, run this command in your terminal [Tested in UBUNTU 16.04]

sudo apt-get -y install libcurl4-openssl-dev

post this install libraries the way you usually do in R using

install.packages("package name")

回答5:

Nowadays (ubuntu 14.04) I need both:

 $ sudo apt-get -y install libcurl4-gnutls-dev
 $ sudo apt-get -y install libssl-dev

回答6:

For my Debian Jessie box, I also included:

sudo apt-get build-dep libxml2-dev

Hint: The r-tool console output is pretty verbose so I would check for any other dependencies.

Then, I finally got it:

> find_rtools()
[1] TRUE

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")

CentOS 7: I had the libcurl and gnutls development packages installed already, but still got the "cannot load git2r.so" error when installing devtools in R. I had to "reinstall" them for it to work:

sudo yum reinstall gnutls-devel.x86_64

回答9:

I hit this issue with Ubuntu 18.04 and none of the previous answers solved it. Eventually I succeeded by installing devtools with the package manager itself:

sudo apt install r-cran-devtools

回答10:

Centos 6.8

this work like charm for me

1. install libcurl $yum -y install libcurl libcurl-devel
2. restart R Software $rstudio-server verify-installation
